Note well: the map will be redrawn using the seed above if you alter any UWP digit. You can change this setting to prevent this by going to View > Your Preferences. If you switch automatic redrawing off, the map may not match how you have changed the UWP (e.g. size or hydrographics may be wrong).

Orbit Details

Orbital Distance:

Adjust orbit with first up and down arrows; adjust the decimal place with the second:

Orbital Period:

World is Tidally Locked to its star

The world's rotational period is the same as its orbital period and cannot be changed. The Axial Tilt is zero and cannot be changed. One side is always facing towards the star and is permanently day, the other is permanently night. The 'day' and 'night' sides are set to the upper and lower temperature limits which is based on the atmosphere.

World is a satellite Tidally Locked to its planet

The world's rotational period is the same as its orbital period and cannot be changed. The Axial Tilt represents the inclination of its orbit around the planet relative to the planet's orbit around the star and so there can be seasonal influences. One side is always facing towards the planet, leading to long days and nights relative to the parent star. Note: The T5 rules specify that satellite orbits 'em' and closer will be locked to their planet. If a randomly generated satellite rotation or user entered result is greater than the orbital period, it will be reduced to the orbital period and regarded as tidally locked.

API Documentation

You can encode a link for a particular star system by using a URL. For example:

http://travellerworlds.com/?name=Junidy&uwp=B434ABD-B

This example will put the world name 'Junidy' in the World Name field, the UWP 'B434ABD-B' in the UWP field, and then randomly generate all remaining details before generating a world map and the star system.

Note that when a system is generated, the main world map and details are generated and displayed; you can then navigate to each world via the Full Star System View and go to another world by pressing the "Details" button next to that world.

All world variables relevant to a world map can be used. Note that the URI needs to be encoded to ensure it works correctly. The following is a comprehensive list of variables used and how they are handled.

hex - the four-digit sector co-ordinate of the system (e.g. hex=3202 - Junidy is 3202 in the Spinward Marches). Default value: empty string.

sector - the name of the sector (e.g. sector=Spinward%20Marches). Default value: empty string.

name - the name of the world (e.g. name=Junidy). Default value: empty string.

system - the name of the system; Default value: the name of the world followed by the hex location and sector in parentheses, e.g. "Junidy (3202 Spinward Marches)". This is used by the map to make the location of the world meaningful when it is a non-main world.

uwp - the uwp in the format SSAHPGL-T where S is the port (letters A-H, X, Y) and the remaining digits are extended hexademical. Default value: randomly generated.

tc - relevant two-letter trade classification, Can be specified as many times as there are relevant Trade Classifications, e.g. "tc=In&tc=Hi". Default Value: generated TCs from UWP, whether the UWP is randomly generated or provided. Use this to specify TCs that cannot be derived from the UWP (e.g. Twilight Zone).

iX - the Importance rating of the world, e.g. iX=4. Default value: generated by UWP, bases and TC values using T5 rules.

eX - the Economic extension for the world including the parenthesis, e.g. eX=(D9E+4). Default value: randomly generated using T5 rules.

cX - the Cultural extension for the world including the brackets, e.g. cX=[5E86]. Default value: randomly generated using T5 rules.

pbg - the PBG 3-digits (Population Multiplier, Belts, Gas Giants). If no pbg parameter is specified, the script looks for the belts, gas_giants, and popMulti parameters and uses their defaults if they are not found.

popMulti - the Population Multiplier (first digit of the PBG), e.g. popMulti=2. Default value: randomly generated even chance 1 to 9.

belts - the number of Planetoid Belts (second digit of the PBG), e.g. belts=1. Default value: randomly generated using T5 rules.

gas_giants - the number of Gas Giants (third digit of the PBG), e.g. gas_giants=0. Default value: randomly generated using T5 rules.

worlds - the total number of other worlds in the system, including gas giants, belts, the main world and other planets. If this value is less than gas giants plus belts plus the main world, it will be raised to that value. Default value: randomly generated using T5 rules.

bases - a string containing all bases present, e.g. bases=NS or bases=W. Possible bases read are N, S, W, and D. Default value: test for bases randomly using Starport and T5 rules. Specify bases= to force bases to be nothing.

nobz - a string specifying all Nobles for this world, e.g. nobz=BcC. Default value: generated from TCs.

allegiance - a string specifying the allegiance of the system, e.g. allegiance=Im. Default value: blank.

seed - the seed used to randomly generate the map. Default value: the hex of the system concatenated to itself. If the hex is not specified, 'undefined' is used.

3 October 2023

New Host: TravellerWorlds has switched to travellerworlds.com instead of an obscure amateur URL. Ahhhh. Professional looking URL.

Bug fix: When a world's atmosphere is 9, atmospheric pressure was using the "very dense" table, which is reserved for extreme Venus-like cases. Was leading to odd results. Many thanks to a sharp-eyed user for pointing this out!

Bug fix: Importance was not reading correctly when passed in via GET data, e.g. from TravellerMap. Allowing reading of the Importance instead of only generating it allows for custom mods to standard Importance values.

11 June 2023

Layout Changes: Working on planet detail layout changes to make it more compact and pleasing to the eye. Paragraph explanations (apart from Government) changed to tables of information.

Bug Fix: Export to CSV was not working; fixed.

31 May 2023

Bug Fix: If 'allegiance' was not provided in the URL, then the world and system were prevented from generating by a fatal error. Now fixed.

Beast Armour: Beast Armour generation added to "View > Beasts (experimental)".

Bug Fix: Half-terrain from Twilight Zones appearing in key for that World Hex Map. Now fixed.

Bug Fix: Beasts of Size 4 did not have Strength modifier applied in Beasts (experimental).

Bug Fix: Locomotion of Beasts in Beasts (experimental) had combinations not intended (e.g. Flyphibians in Clear terrain).

Bug Fix: Download buttons for World, Terrain and Local hexes were not working. Fixed.

Bug Fix: Cropped Map image had incorrect file extension of "svg" instead of "png". Fixed.

Experimental Beasts: Beast tables generated through a modified rule set. Thus, "View > Beasts (demo)" is RAW, "View > Beast (experimental)" is modified rules.

18 April 2023

Beast Maker demo: For any world you can choose View > Beasts (demo) to generate beast tables for each of 11 terrain types. This feature will be improved in future to fully edit the beasts including all T5 details and save the data with the system.

8 April 2023

10 september 2022.

Bug Fix: Belts could not be placed by using "System Actions > Add a celestial object to the system" due to an error caused by the new Belt Details release. Now fixed.

24 July 2022

Bug Fix: The fix for the different results for seeds had knock-on errors that slipped through my testing, and affected nearly any world one would attempt to generate by navigating from TravellerMap. Now fixed.

17 July 2022

Bug Fix: This was a misconception on my part. The "number of worlds" statistic for a system indicates the total number of gas giants, belts, and other worlds in the system. I was getting it to generate other worlds ON TOP OF gas giants, belts and the main world. Systems will look smaller from now on.

Bug Fix: Saving and loading systems was changing the position of stars and messing with other objects as a consequence. This was due to the seed for the system not being read correctly.

Bug Fix: The system generation was giving a different result almost every time, whether data was coming in from Traveller Map, the user was entering their own data, or the user was regenerating with the "current seed". This error was due to me not being careful with when and where I initiated the RNG with the correct seed.

9 July 2022

Belt Details and map: Planetoid and Asteroid Belts now have details generated - their zones, and the total belt width, and the predominate and maximum sizes of objects in the belt. The Belt now has a map indicating the relative size of each zone. All belt details are fully editable and saveable with the system.

Twilight Zone alteration: Ice cap terrain is now removed from Twilight Zone worlds.

Habitable Zone reset: The Habitable Zone value for each star has now been refined to a decimal orbit (where each 0.1 is 10% of the distance from the inner orbit to the next orbit). If the Main World is to be placed in the precise Habitable Zone (i.e. not HZ+1 or HZ-1) then TravellerWorlds now places it in this new refined value. The new HZ value has been calculated by the distance that a planet with Greenhouse of +10% and Albedo of 0.3 would need to be from that star for an average temperature of 288 K / 15°C. Note that due to varying Albedo and Greenhouse effect this will not always be the exact temperature. This more exact placement is to help world builders obtain more Earth-like conditions more easily; many results quite frankly created extreme worlds even if they were Ag Ri Ga worlds.

4 July 2022

Bug Fix: Fixed an introduced bug stopping Local Hexes from completing correctly.

Bug Fix: When Cultural Extension and Economic Extension data was not passed to TravellerWorlds it would freeze.

Importance: Importance is now imported from data rather than only generated. It can also be edited by the user. Its default value is to generate the Importance rating using T5 rules, but it can be edited by the user (e.g. when establishing capitals).

Star Details: When editing star details, calculated values (luminosity, mass, diameter, jump point) are displayed and updated as you edit.

Gas Giant Details: Gas giant details can now be edited, and details such as mass and jump points are displayed and updated as you edit.

3 January 2022

Bug Fix: In the background, the map was generating a random map before loading the data because this was required for the setup before data was loaded. Set up and generation are now separate procedures.

Bug Fix: In map editing mode, certain hexes were incorrectly creating a World Hex Map when clicked. Now fixed.

27 December 2021

Map Editing: There is now a (very basic!) map editor. This is an EARLY version and is still buggy, but the basics work. Navigate to the world you wish to edit, and then choose Map Actions > Edit the Current Map. Then click on one of the types of terrain at the top. Clicking the hex will add the terrain. You can remove symbols (e.g. rural, cities, etc.) by clicking again. Base terrain (e.g. clear, oceans) cannot be removed but can be replace with other terrain.

Bug Fix: Atmospheres of types exotic, corrosive and insidious had a bug where the atmospheric pressure table was not saving correctly, leading to all sorts of loading and saving problems. Some of your older systems might still not be able to save or load correctly, many apologies.

23 December 2021

Background mapping change: new political border terrain added in anticipation of being able to edit maps. Users can edit the downloaded JSON of worlds to add these codes in. Users can also change the default colour for these borders.

22 December 2021

All UWP details explained: Each digit of the UWP for each world is now fully explained - the last to be added were law level and technology level.

Add objects: The user may now add objects to the system - stars, gas giants, planets and satellites

28 November 2021

Bug fix: When changing orbits of worlds, Trade Classifications and Remarks (in particular: Ho, Co, Tu and Tz) were not updating correctly. The drawback is only that 'custom' remarks such as Ownership codes (e.g. O:2355) will be removed if you change orbits.

Bug fix: Orbits of satellites could be changed and the change of the name would save, but the orbital distance, rotation period and locking status would not change. Now fixed - changing any satellite's orbit updates the orbital distance, orbital period, and recalculates whether the satellite is locked to its planet and if not randomly generates a rotation period.

Bug fix: When loading a system from a JSON file, TravellerWorlds was regenerating the map using the seed instead of loading the map data. In theory, a user can edit the JSON file directly and upload the file to show terrain the user has put in such as extra cities, a second starport or other features. At present, this editing can only be done by the user directly editing the JSON file using a text editor.

Bug fix: If you change a digit of a UWP, the map will now automatically be redrawn. In anticipation of users being able to edit their own maps, this can be turned off so that users can make minor adjustments if they have edited the map and prevent their work being overwritten.

25 November 2021

Bug fix: Map data was not saving and importing correctly when using expanded noble estates

Bug fix: When regenerating the whole system, the main world details were displaying incorrectly in the table showing symbols for each celestial object.

Edit Star Details: You may now edit the Spectral Class and Spectral Size of the star, and vary its luminosity, size and mass using a multiplier for the base values. At present, this still allows you to put in unrealistic values, so no warranties provided as to realism.

18 May 2021

Generate missing data: upload a CSV file of names and UWPs, and get back a CSV file with all T5 details generated.

16 May 2021

Bug Fix: Travel times to jump points were calculating incorrectly because I had forgotten to convert units properly. Thanks to BasicPassage on Citizens of the Imperium for bringing it to my attention!

15 May 2021

Map Data download: Terrain data for a world map (only) can be downloaded as a JSON file. I will be posting a help page to explain how the data works so you can use it in your own projects. In the background, when you save a system, the actual terrain data is saved and loaded, so you can generate maps until you get one you like before you save the system or download it as a JSON file. JSON files of the whole system now include generated maps. The ability to save the actual terrain data is a pre-requisite to being able to edit the data. Yes, you read that right. Watch this space, O Patient Users.

16 April 2021

Matt Stevens government detail: I use Matt Stevens wonderful series of articles to fill in a text giving more detail about the government for each world. You can read more from him about how to give more detail for dictators , bureaucracies , democracies , balkanisation , religious governments , and feudal technocracies .

26 December 2020

TravellerWorlds launches - I put all of the application onto one page, fixing multiple bugs. This vastly simplified the code.

Twilight Zone removal - so many worlds end up being a 'Twilight Zone' because of system generation rules. The user can now just remove the Twilight Zone from the map so that it is a help utility rather than imposing unexpected outcomes on a world builder. You can always elect to keep the TZ, of course. Rob Serling would be proud

Hex map generation - when World, Terrain and Local hexes are created, they appear on top of the world map rather than appended to the bottom. They can still be downloaded onto a user's computer.

User Preferences - you can now save a profile of your preferences - various system and map generation options INCLUDING choice of colours for the map!

25 May 2019

Change of Name: Instead of "T5 World Builder" the website is now called "Traveller Worlds". The URL is still the same, but ... watch this space. Also layout changes.

System Symbol Map download: the System Symbol Map is now downloaded with the HTML file

Scroll down to Hex Maps: when you click on world, terrain or local hexes, the browser now scrolls down to the map for you.

23 May 2019

System layout change: The system symbol map is now automatically generated when the system is generated. Both the system table and the symbol map are updated when any world details are changed.

Details enhancement: For main worlds only, the cultural extension and economic extension can be edited or recalculated in the World Details in the system editor.

Bug Fix: Resources now working correctly in the world details.

Bug Fix: Satellite orbit selection box now appears only for satellite details and correctly alters the satellite orbit to the user's choice.

Bug Fix: "Wasteland" incorrectly spelled as "Waste land".

8 April 2019

Bug Fix: Download buttons for system data not working correctly, now fixed.

Native Life: Native Life simplified. Now simply a roll of Average (2D) < 2, Mod -3 if Atmosphere 0; Mod +4 if Atmosphere 4-9; Mod -2 if Hydrographics 0; Mod +1 if Hydrographics 2-8.

Native Intelligent Life: Implemented a 'house rule': two variations on T5; a "no sign of intelligent life" for vacuum rock balls that are otherwise skipped in the NIL rules. And 'Established Transplants' and 'Established Exotic Transplants' which are worlds with population 7+ without Native Life that otherwise meet the requirements for Natives and Exotic Natives.

10 February 2019

Bug Fix: Fixed Blank Map feature - it works again.

Bug Fix: System was not generating any minor worlds - this was due to code that was intended to cap the number of minor worlds plus gas giants plus belts plus the main world to fit in 20 available orbits. Some legacy data in Traveller Map has more system objects than 20, enough to break the script.

2 January 2019

Bug Fix: When the main world is a satellite, the planet it is orbiting (whether a Gas Giant or a Big World) now has other satellites generated correctly. Previously the main world would be the only satellite of the planet.

1 January 2019

Save and reload your work: When on the System page, you can save your modified system and re-load it at a later date. The data is stored within your browser. This allows you to manually alter any aspect of your star system, taking advantage of the calculators built into T5 World builder, and work on it over time before exporting it to your favourite format.

Import and Export systems: In addition to saving your work within your browser, you can export it as a JSON file and also import saved JSON files.

Native Intelligent Life and Native Life: if the T5 rules generate native intelligent life, the world now automatically has native life.

Bug Fix: When the number of worlds in a system was not specified by Traveller Map data, the number was not being generated randomly. Now fixed.

Data interpretation: Many worlds in the OTU have a 'worlds' statistic of more than 12. This has the potential to break the system generator if worlds plus gas giants plus belts plus the mainworld exceeds 20 orbit 'slots'. For now, if the 'worlds' statistic is more than 12, it is reduced to 12.

Bug Fix: Native Intelligent Life was not generating correctly.

18 November 2018

Edit World Details: All planet and satellite details can now be edited when you press on the Details button next to them. This allows all values including the UWP to be adjusted. All details are automatically recalculated if needed in real time.

Jump Points: As part of the new Edit World Details feature, every world's Jump Point is calculated in kilometres, including accounting for the parent star and parent planet (if the world is a satellite). Also included is a table of travel times to the Jump Point from 1G to 6G.

New Satellite Option: Under System Options, you can select an option that prevents tidally locked worlds having any satellites. This comes from my own experimenting with Universe Sandbox - satellites of almost any Traveller size are torn apart if the world is close enough to the star.

Download World Details: When the system is generated, there is a check-box to indicate you want all details of each world downloaded with the system data. It is checked by default. So I'm generally assuming you want more detail rather than less.

Small worlds: The system generator now distinguishes between Asteroid and Planetoid belts and worlds that end up size 0 through modifiers or size limiting (typically satellites). You can now generate and edit the details for these particular objects. The diameter is randomly generated, ranging from about 260km - 700km.

New Barren Option: Under System Options, you can indicate that if the main world population is zero, all minor worlds will be generated as barren (i.e. population, government, law level and TL will be zero). If left unchecked, the T5 rules will be used, which can result in notional populations of less than 10.

Bug Fix: When the size of the world is less than five and hydrographics more than seven, oceans were not being placed. This is now fixed.

Bug Fix: System orbit based Trade Classifications (e.g. Hot, Cold, Twilight Zone) now automatically update when orbit is adjusted.

Bug Fix: Map was placing cities in every hex in Size 1 worlds regardless of population. Now fixed to operate according to T5 rules.

28 July 2018 - second release

Layout: changes to the home page to take advantage of a wider space for "Enter, Review and Change World Details".

Noble Estates: option added to allow noble estates to be placed on ocean or sea hexes.

Multiple world maps: option added to allow up to 10 maps to be generated at once. This helps users hunt through several maps at once to find a suitable one.

28 July 2018

Code Optimization: when the code needs to fetch individual hexes, it uses an associative array to look up the hex instead of iterating through all the hexes in a map to find the correct one. Hopefully this gives a significant speed increase for future development where we want to do more complex stuff.

Minor bug fix: map key for world maps was oddly offset off the map for smaller sizes (1, 2 and 3) and spilled over the right edge for larger sizes.

Bug fix: black and white map and noble state flags were not being read correctly.

Bug fix: for Terrain Hex and Local Hex maps, the 'shore line' now works as intended - "creeping" ocean or ice cap from neighbours onto the current hex.

24 July 2018

GET Data parameters: added a 'pbg' parameter for more conveniently specifying the 'Population Multipler, Belts, Gas Giants' in a star system.

23 July 2018

Bug Fixes: Fixed information about the random seed, system name and sector names in the URL passed to both the system and map generators.

Bug Fix: Updated the API documentation to reflect developments in the code.

Layout change: Changed the layout of the main T5 World Builder page to put map and system flags at the bottom, in anticipation of more options being added.

21 July 2018

Bug Fix: The various 'download' buttons (HTML, Plain Text and CSV) downloaded the actual javascript functions instead of their function results. Also, having changed from "energy absorption" to "albedo" for worlds, I had forgot to update the information in these downloads and so it would have included Energy Absorption (which is one minus albedo) instead of albedo, leading to confusing figures if you wanted to play with them yourself.

15 July 2018

Bug Fix: The trade classification "Lk" (i.e. satellite is tidally locked to its planet) was not being correctly applied to satellites. This had the consequence of the rotational period formula generating rotations much larger than the orbital period because the formula takes into account the planet's mass and distance from it.

Display change: Star data (mass, luminosity and radii) is now spread over several columns, making the table look a bit better.

14 July 2018

1) All stars in the format "M9 D", "F6 D" etc. are converted to the identical class with size "V" instead.

2) F0 - F4 VI are converted to F5 VI

3) K0 - K5 IV are converted to K6 IV

4) M0 - M9 IV are converted to the identical class with size "V" instead.

In addition, the code was falling over when it did not find any star data. In these cases a pre-fill of the star is not attempted but other data is filled out.

If you find a sector is not loading any worlds and is not leaving the message "No World Data available" it is generally because there is something in the legacy data the code does not like. Please bring these cases to my attention! A sector name is enough.

13 July 2018

Bug Fix: Noble Estates will no longer be placed in open ocean.

Equator Line: All world maps now have a dashed line at the equator.

Blank Maps: Under the Options on the main page you can generate a blank world map of sizes 1 to 19. I invented this to help with analysis, and thought others might want it too.

13 April 2018

System maps. When a star system is generated, there is a new 'Create system symbol map'. It creates a symbolic map of the system in the style of Joshua Bell's prototype code found here: https://travellermap.com/tmp/sys.html .

Place Several Noble Estates option added. This will place a number of World Hex level Noble Estates based on the Nobles field. One Noble Estate World Hex will be placed for each of Knight, Baronet, Baron, Marquis, Viscount, or Count. Two estates will be placed for Dukes, and Four for Capital Dukes. When the World Hex Map is generated, the number of Terrain Hexes placed as Noble Estates varies based on the type of nobility of the estate. For a Knight Estate, one Terrain Hex will be placed; Baronet is two; Baron is four; Marquis is eight; Viscount is sixteen; and Count or Duke is thirty-two. Thus, the correct number of Terrain Hexes is placed for each noble, bearing in mind for that Dukes there is more than one World Hex of estates.

Names of celestial objects can be edited. In the system generator, the user can add names to all objects and they will form part of any download of the system.

World name on maps. The world name as edited in the system generator is now added to the map. The system name (i.e. the main world name plus hex and sector) is also added; some modifications to map layout as a consequence.

Layout. Generate buttons are now at the top of the layout rather than the bottom.

Coding rationalisation. This will make it easier to expand in future, BUT there may be bugs. I have tried many combinations successfully for all options but it is difficult to test for all options. Please report bugs!

7 April 2018

Minor fixes and enhancements this time around: the Main World is now placed according to the T5 rules: if it is an asteroid belt, it is placed randomly without considering the habitable zone. Otherwise it is placed according to a roll that can place it in the orbit just inside the HZ, in the HZ orbit, or the next orbit outside. Similarly, the main world will be rolled for a random chance to be a satellite.

To help placing the main world where Referees feel it must be a planet or must be a satellite, I have added options to force this choice. I also added back the option for a black and white map (sorry, Marc, it was taken away by accident!). I have also added an option to stop the placement of a Nobel Estate if desired.

Satellites are now placed in different orbits - except for Ring Systems (fix to come).

The BIG change: the system generation table. Energy Absorption (i.e. one minus Albedo), Greenhouse effect and Average Temperature are now calculated for each world.

You can now adjust the orbit or decimal orbit up or down using the arrows. This allows 'fine tuning' of planets positions to suit the temperature you envision is average for that world. The values are recalculated for you.

The download formats have changed. You can download the system in HTML format - it is a plain unstyled format of the data (no functioning buttons. Additionally, the data can be downloaded as plain text, or as CSV which can be opened by spreadsheet programs.

28 March 2018

Marc Miller's requested feature was an interesting challenge and I dropped working on other code to make it work.

Each map now has a " " button above it. They slide all of the terrain left or right over the world map. This allows slight adjustments to get important hexes (e.g. the starport and main town or a noble estate) into the centre of a map or triangle.

The initial attempt simply got each hex to grab its west or east neighour's terrain to rotate the terrain around the globe. The intriguing problem was that the polar regions ended up distorted because of the way that hexes north of the pentagons move west or east - because suddenly, relative to the middle part of the map, the hexes are 'moving faster'.

The solution I implemented simply moves the top and bottom regions more slowly than the middle region. This does not remove the distortion, but minimises it so that the polar regions keep the rough shapes of the terrain they have relative to the rest of the globe. Moving back and forth an arbitrary amount will still distort the shape. But it should be robust enough to make a minor adjustment without completely changing the map.

To understand this problem, I had to print out a larger world (I chose a Size 9 world) with 50% hydrographics to give some interesting shapes, and then cut it out and fold it into the duodecahedron to visualise the problem. It was fun!

17 March 2018

This release contains two updates. I have re-worked the Sector list - and unfortunately I have had to do away with multiple milieux of the same sector.

HOWEVER, what I have added is that the last sector selected by the user is now automatically saved. When the page is loaded again, the name of that sector is selected by default, and the worlds of that sector are loaded into the 'Select a world:' list.

Marc Miller has requested a feature whereby we can move the rendering of the hexes east and west so that the main town with the starport or the city with the starport can be shifted towards the middle of a world triangle. This is possible but will take some time. It will be extremely awesome when I get it done. Even if I do say so myself. As a first step, I have simply stopped the starport being placed in the half-triangles the current east and west edges of the map. This can still leave the starport positioned awkwardly on a half-hex between two triangles.

I am proud to announce that the system generation table now includes a link to map any world in the generated star system. At the touch of a button, you can generate a map for any planet in Chartered Space, or your own Traveller Universe.

The next step will be to make the names of objects in the system editable so that you can download more meaningful data. I will also be working on downloading and uploading your own data into the system generation table so that you can save it and keep working on it. This is an important precursor to being able to edit and generate details for each world such as gravity, temperature and so on.

24 February 2018

Download As HTML and Download as Plain Text buttons added to the generated systems page. The plain text file is a fixed-width data file - each systme entry is padded with spaces. The HTML is an HTML file that includes the style sheet used by the T5 World Builder pages. This means you can open it in your favourite word processor to edit it and save it.

Future formats to be added for the system are tab-delimited and CSV. CSV format allows the results to be imported into spreadsheet programs.

If the sector you select from travellermap.com has no world data, the world selector will now say so. All data from travellermap.com is now available to play with. Where a sector does not have names for its worlds, the sector hex coordinate for each world is displayed in the world selection list.

18 February 2018

Bug fixes to get World Hex, Terrain Hex, Local Hex maps working correctly. Also fixed the Download Map buttons that stopped working. System data table cleaned up slightly.

All travellermap.com sector data - Official OTU or not - is now accessible from the Select Sector drop-down box.

22 January 2018

Published a draft Traveller5 extended star system generator. At present it is little more than a proof-of-concept leveraging the code created for the Map generator.

It is published as a separate web page because I'm lazy and I developed it as a separate page in my sandbox. However, it will be integrated into one page in the near future with a title something like 'Traveller5 World Builder' with buttons for either generating a map or a system.

Then the real fun starts: after developing the system format more and clarifying naming conventions for unnamed objects, put a link next to each world (not Gas Giants or Planetoid Belts to generate a map.

Any UWP listed as "???????-?" in travellermap.com data (see especially Corridor Sector Data is not added to the World List for selection.

The main world is always placed in the first available Habitable Zone. This will change in future and the table on p. 408 of the T5.09 rules will be used. I did this to simplify things while I worked out how to determine system zones and other system related conventions.

Determining whether a given Satellite is Close or Far is done using the Book 6: Scouts throw (roll 2D: 7- = close, 8+ = far), and then rolling on the relevant column of table 2c on p. 408 of the T5.09 rules.

Size zero is allowed for objects other than Planetoid Belts. This is especially important for satellites because where a satellite's size is equal to or bigger than its planet, I have implemented the original T5 core rule that it is reduced to the planet's size minus 3 (p. 437 of the T5.0 core rules). In these circumstances, it should be interpreted in a similar way to Size 'S' of the original Book 6 extended system generator.

Ring system orbits are rolled for using the 1D table found in Book 6: Scouts on page 28.

7 November 2017

Implemented a polyfill for URLParameters to ensure links to particular maps are more robust and the code is simplified.

Layout and style changes to make the user interface more logical and with a clear order.

5 November 2017

The main noticeable change is the random number generator. A new smaller generator by Rob Eaglestone and converted to javascript by Joshua Bell is now in use. That means the nature of the seed has changed. Instead of a 256-character string, it is an integer between 0 and 4,294,967,295. If you have saved bookmarks to your favourite maps using links previously, many apologies.

The new random number generator is faster, and the app can cope with up to size 20 worlds ... but you may have to tell the script to 'continue' if asked because it will take time. My aim of being able to generate Size 33 ('Z') worlds is still unfulfilled.

Layout has been modified to include tool tips and adjusted so that the 'Generate Map' button is more prominent and at the top of the screen.

There have been many backend coding changes to make the app more robust into the future. There will be a few more changes to the user experience and background code into the future.

The rules interpretations will be better documented at some point in the future and circulated for discussion.

21 October 2017

Many thanks to Joshua Bell of travellermap.com fame for casting a professional eye over the website. He raised a host of issues which I am working through.

The first change is a to the general user experience. So there have been major changes to layout. Navigation bar to explanatory and background text introduced. User input now gathered at the top with less scrolling down to buttons to get the action going.

For now, functionality is the same. There will be changes to the random number generator coming to speed up generation - this matters for larger world sizes. There will also be various background changes to the code based on inexorabletash 's feedback. But one thing at a time!

As always, feedback is welcome. Just e-mail me - I have a gmail account - jonathan dot a dot sherlock.

7 October 2017

You can now drill down to the World Hex, Terrain Hex and Local Hex levels. Click on an individual hex in any hex map to drill down to the next level. All maps include a key and a scale.

I have roughly documented my interpretations of the rules in this PDF file. As always, feedback is welcome - I have a gmail account - jonathan dot a dot sherlock. I would very much like feedback on interpretations of the rules, but also on website layout and, of course, any bugs.

1 October 2017

You now have the option to generate a map in black & white. This makes it easier to photocopy.

29 September 2017

The API is now open in a similar way to travellermap.com .

The "API Documentation" help button under the "Select A World" heading gives more information about how to use it.

Every map generated also has a URL posted beneath it to enable a direct recreation of that map using the world data just used.

I have changed the random number generator to a faster algorithm with the seed still exposed. If you have saved seeds, many apologies, they will no longer produce the same map.

It is now much faster. Although trying to generate a Size 20 world will give the 'script is taking too long ... continue or stop script' message, if you continue, it will generate the world. Try it, it's fun (just substitute "L" for the size digit in any UWP).

I have not managed to successfully generate a Size 33 ("Z") world yet. That's too much for my browser. Post photos at CoTI or the Traveller RPG Facebook group if your computer can do it.

26 September 2017

This release fixes issues with World Hex maps and contains many background updates to rationalise the code.

If you click on a Frozen Lands hex next to an Ice Field hex, the Ice Field now "creeps" onto the Frozen Land in a similar way that ocean "creeps" onto land to give wriggly coast lines.

Half-hexes for Twilight Zones are now imposed on World Hexes and are a bit wriggly.

Ice-caps now "creep" onto neighbouring hexes World Hex maps.

Overall, the World Map provides an abstracted collection of world hexes, while each individual World Hex map provides more of the "crinkly bits" so beloved by Slartibartfast.

18 September 2017

In this partial release, precipices and the two precipice lines for chasms are now traced onto World Hex Maps. I am not completely satisfied with the results.

The generator picks a random hex edge for the start, a random non-adjacent hex edge for the end, and picks a start and end hex from those edges. Then it traces a random path from one to the other.

The script does lock up occasionally because of a do..while loop that becomes infinite somehow when generating a World Hex Map with a chasm. But it happens so rarely I thought it worth a release.

The two precipice lines of a chasm are in different colours so you can see what the generator has attempted to do even if the line turns out to be a funny shape.

10 September 2017

This is a partial new release. World Names with UWPs are now bigger and at the top of the world map. The Download as PNG button now renders the SVG graphics at a higher resolution.

In future I plan to implement letting the user choose the resolution of the PNG button. At present a typical size 5 world is about 300kb - 400kb with the new resolution. The trade-off will be better resolution for a larger file size.

But most exciting for me, click on the background (not the terrain symbol!) of any hex on the world map and you get a map of that world hex. I acknowledge this may cause issues with touch-screen devices.

World Hex Maps are only in draft form. I am still to implement Chasms and Precipice lines; the rules simply state "draw a precipice line through the hex" and I need to decide how this will work to be suitable squiggly and work in with shorelines and other terrain.

At present, World Hex Maps do not take into account half-hexes in Twilight Zones. I also want Frozen Lands and Ice Fields in Twlight Zone and Frozen worlds to have "shorelines" that are squiggly in a similar way to normal oceans and lands operate now.

So check out a favourite world map, then generate a variety of World Hex maps. You can download them in SVG or PNG format.

26 August 2017

Instead of over-writing the world map when the "Generate Map" button is pressed, a new map is added. The map download buttons are now produced for each individual map. This allows users to generate multiple world maps for different worlds without starting again and still having access to previous maps generated in a particular session. It also allows for using different random seeds until a satisfactory result is produced.

Marc Miller has e-mailed in some great suggestions. I will be working on them next, but for now I want to implement World Hex maps. I will work on Marc's suggestions after that, before getting back to Terrain Hexes and Local Hexes.

I also had a request to implement a 'Seed Me!' button. This quickly creates a new random seed. This means you can load or enter a world, generate a map, and if you don't like it, press the "Seed Me!" button and generate another map. You can compare all the maps you have generated before downloading your preferred one.

16 July 2017

The seed for random numbers is now exposed. Enter any string upto 256 characters in length, or leave blank for a random seed. If you wish to save a seed, copy and paste the seed for yourself. I may add a "saved seed" library for individual users using cookies or an equivalent.

This now uses a custom script that modifies the javascript random function. The penalty is a cost in speed. I have found when generating larger worlds (e.g. Size 18+) the script now takes 10-12 seconds.

15 July 2017

Ocean placement is now randomised, not just world triangles marked off as oceans. Maps are now looking heaps better.

This meant I had to change the definition of a 'continent' for the purpose of placing features that the rules require placement of 'one per continent'. A continent is simply all the land hexes in a particular world triangle, regardless of whether they are separated by ocean or not.

To get around world of lower size (less than 5) and higher oceans (more than 7 for hydrographics), the program now simply selects a certain percentage of hexes overall as ocean hexes instead of trying to place separate oceans in neater shapes. The randomly placed hexes on these kinds of worlds generally work out to a reasonably pleasing shape given there are few land hexes left.

To simplify placement of settled areas, all settled areas must now be placed on land or islands.

I will be working on exposing the random seed generator next.

11 July 2017

Twilight Zone now works except for Size 1 worlds. For now, all settled areas (cities, towns, arcologies, starports, cropland and rural areas) are still placed randomly, ignoring the Twilight Zone.

Users will have the option, in future, to control where settled areas are placed. But I need to change the way that oceans are placed which will change assumptions about what constitutes an 'ocean' and what a 'continent' is.

9 July 2017

Map key added.

Rendering of world details with neat black outline added. Open to feedback on design.

Map can now be downloaded in either PNG or SVG formats.

7 July 2017

Option added to select a world from OTU sectors using travellermap.com data.

Users now enter comprehensive T5 data, or modify what was loaded before generating and / or downloading a map.

BUG FIX: to enable worlds to load in Chrome.

5 July 2017

Map generator first published. User input a name and UWP and number of resources, and the generator calculated Trade Codes and generated the map.

Best contact is e-mail: jonathan dot a dot sherlock at gmail.com.

I can also be contacted at Citizens of the Imperium . My username is OjnoTheRed .

Please report bugs! I test the code myself but there are always combinations I could not foresee.

I also love suggestions for future development. If it's not on my to-do list, you can put it on my to-do list.

Lastly, do you have your own application and wish you could take data from here? E-mail me and I will probably be able to get the data supplied in a format you want.

Edit star positions so that Close Companions can be changed to other orbits, and stars can be made Close Companions. I may reconfigure how orbits are edited completely.

Better layout for the world details

Traditional World map size - option to have traditional one-size maps based on Classic Traveller.

BeastMaker - either a bunch of tables for the world, or generate an encounter table for particular terrain hexes

Weather and seismic events listed next to every Terrain Hex based on Grand Survey.

Generate Sophonts for relevant NIL values

Cargo calculator - including saving calculated cargoes to a list for recall to sell cargoes on a particular world.

Plant Maker for colour and description

Variations for World Hex, Terrain Hex and Local Hex maps - greater random variations to layout.

Edit World Hex, Terrain Hex and Local Hex maps - they will save with the star system.

Maps and data, library data and astrography.

This library data section is not alphabetically ordered. Instead it is location ordered, so that You easier can find what is relevant for a specific planet.

GypsyComet, Dylan Lee and I have mapped the Foreven Sector . Foreven Sector is directly spinward (left) of the Spinward Marches .

The Space Atlas:

• The Classic Galaxy ( dotmap )
• The TNE Galaxy
• The T20 Galaxy

WARNING, Horizontal scrolling ahead!

Making your own subsector:

Check out the Random Subsector Generator . Make as many Subsectors as you want…

If you make your own Subsector, Have a look at this post: What makes a Subsector popular?

For the TML Landgrab , I have grabbed Cipango (Chronor 0705)

Four very good mapping programs are:

• Traveller Universe
• Galactic 2.4 (Yahoo Group)
• Heaven & Earth
• sec2pdf (Makes pdf from sector files)

Some ATU Subsectors:

• Merry X-Mas
• A Vargr Subsector
• Origo Point Subsector (Tutorial)

4 thoughts on “Maps and Data”

Excellent new look and the Striker Video is killer. Thank you for all the great work you do to keep Traveller alive.

I can’t see any jump-6 images…

Any idea how to get Universe these days? Not getting any response from BITS.

Peter Trevor made Traveller Universe . You can also find him at facebook .

A database of all the worlds in Traveller space?

• Thread starter Agrikk
• Start date Jun 28, 2007
• Jun 28, 2007

I've seen web sites that have star maps that you can drill down through to see the individual stats of a single world. My favorite hase to be this one: http://www.rossmack.com/ab/RPG/traveller/ChartedSpace/ChartedSpaceLoaded.asp It lists the information about a bunch of worlds with their UWP stats and text descriptions about the mainworld. I expect this site and many other sites like it are run off of a database of all the planets that have been collected from all of the different sourcebooks and materials collected. I am trying to build my own database for my players to reference using these stats as well as custom information I have added for my game. Does anyone know where I can get my hands on a master list of all of the planets that have UWPs associated with them from the Canon? I don't care what format it is in. I'll take what I can get.  

inexorabletash

My map site lists the data sources I've used: http://www.travellermap.com/info.htm And I highly recommend this for vetting the sources against "canon": http://winterwar.prairienet.org/dmckinne/sector.html Nearly all of the data is available online, but there tend to be multiple variations and additions.

My own stuff I have a bunch of components I've written using TCL/TK. These are not what I'd call production software, as they completely lack documentation, but if folks are interested I can dust them off and provide them. They'll run on nearly any machine as the stuff is OS independant. The tools I have are: GUI subsecor browser -- Missing a couple of features still Mass SS generator -- Takes a picture which uses grayscale as density map and makes 1-hex-per-pixel SS to HTML -- Makes a pure HTML subsector grid map. Anyway... let me know if there is some interest.

tarball them, and put it up in the files.

Traveller Cheatsheets

In my How to Learn a New System post, I said that I like to make cheatsheets before embarking on a full campaign, and I gave a cheatsheet I’d made for Traveller as an example.

This post has an updated version of that sheet, and all my other Traveller sheets. I’ve been using these for a few months now (except for the space piracy one, which is fairly new), and these are the first things I get out when sitting down to run a session.

These sheets are for Mongoose Traveller 2e, using the pre-2022-update rulebook. I don’t think the 2022 core rulebook update significantly changed anything, but if you have that you should double-check before using these.

Basics , covering:

• Checks (with the optional luck rule from the Traveller Companion)
• Common weapon traits
• My house rules for healing and rumour gathering

I know this more or less off by heart now, I don’t need to look at it much. But it’s handy to have open just in case.

And here is a version without the house rules .

Spacecraft , covering:

• Common skill checks
• Skimming fuel from gas giants
• Running costs
• Jump travel and misjumps
• Damage and repairs
• Common travel times
• The challenges of being in space: zero-G, life support, and exposure to vacuum and radiation
• Space combat (including the critical hits table and examples)

This one is three pages. Not ideal, but I refer to it all frequently.

Universal World Profile (UWP) , covering:

• How to read a UWP
• Starport qualities, berthing and fuel costs, and facilities
• Trade codes
• Travel zones

I mostly use this for the list of berthing costs. I’m using the official Traveller setting in my campaign, so I can use the excellent travellermap.com , rather than needing to decode UWPs myself.

Piracy , a recent addition based on the Pirates of Drinax books, covering:

• Lists of random ships by type
• Attacking other ships: distress signals, morale, and looting times
• Piracy response from local world governments
• Piracy response from the Third Imperium and Aslan Hierate
• Refuelling times
• Stealing ships
• Transferring cargo in zero-G
• NPC crew: salaries, morale, and dividing the spoils

Also a three-pager, but the third page just covers NPC crew, and which I don’t expect to need to refer to very frequently.

The Traveller Map

Traveller is a role-playing game set against a background drawn from adventure oriented science fiction.

In the distant future, interstellar travel is as common as international travel is today. The tremendous distances involved in travel between the stars dictate that such voyages take weeks, months, and even years. A situation similar to Earth in the eighteenth century is created, where communication is limited to the speed of travel, and the stage is set for adventure in a grand fashion, with all the trappings of classic science fiction: giant, star-spanning empires (good, evil, or both), huge starfleets, wily interstellar merchants (or pirates, depending on your point of view), complex diplomatic maneuvers, larger-than-life heroes, heroines, and villains.

— The Traveller Book

The Traveller Universe

The Official Traveller Universe (OTU) is the primary setting for various editions of the Traveller game, owned by Mongoose Publishing. This is the universe described by publications from Game Designers' Workshop (GDW), Far Future Enterprises (FFE) and Mongoose Publishing, and by past licensees such as Digest Group, FASA, Imperium Games and others. The setting includes the Third Imperium, Zhodani Consulate and Solomani Confederation, alien species such as the Aslan, K'kree, Vargr, Hivers and Droyne, and a history from the Ancients through the New Era.

Under the Fair Use Policy , the Traveller Map presents an interactive view into the OTU, making use of official data approved and provided by FFE — as well as apocryphal and unofficial data.

Official and Unofficial Data

The status of a sector's data is called out when the sector is clicked or centered in the map view. Official data has no annotation - this is data supplied by FFE's Traveller 5 Second Survey (T5SS) project. Some data is still In Review and further refinements are expected - corrections and feedback is appreciated. Unreviewed data was officially published data for one of the many prior revisions of Traveller but has not yet been reviewed by the T5SS; it is expected that this data will become official eventually.

In contrast, Apocryphal data was formerly supplied by Traveller licensees but is no longer considered official; all, none, or some elements of this data may be retained when analyzed by the T5SS. Unofficial data was created by the Traveller community, including organizations such as HIWG and individuals. Mixing official and unofficial data within the same map may be concerning to those who want an authoritative, unassailable and pure source of truth. Those who are familiar with the lore of Traveller will recognize that truth is a rare commodity and slippery substance, and often contains contradictions and unsettling gaps. Even the official data is intentionally incomplete, and may contain mistakes, secrets, lies and deliberate omissions.

Tips and Tricks

Search tips.

Use the search field to look up worlds, subsectors, sectors, and regions by name. By default, searches use "prefix" search. So reg will find the Regina system and the Regina subsector, among others.

You can use * and ? as wildcards. * matches zero or more characters, so *ward will find the Spinward Marches sector. ? matches exactly one character, so t?rra will find the Terra system. You can also use character ranges like [8-C] or [89A] .

Specify uwp: to search UWPs. For example, uwp:*-g will find tech level 16 worlds. uwp:B[5-7][6-7][3-9][4-8]?[4-7]-[B-D] will find all starport B, medium size, standard atmosphere, wet, moderate poulation and law-level words with average stellar tech level.

Specify pbg: to search PBG. For example, pbg:??0 will find systems without gas giants.

Specify zone: to search travel zones, using G for "green" or no zone. For example, zone:A will find Amber Zone worlds.

Specify alleg: to search allegiances. For example, alleg:Im* will find Imperial worlds (in any domain).

Specify stellar: to search stellar data. For example, stellar:"M? I*" stellar:D will find red giant stars with white dwarf companions. (The question mark matches any spectral digit, the asterisk finds any luminosity class starting with I, and quotes are needed because of the space between the spectral class and the luminosity class.)

Specify ix: , ex: , or cx: to search T5 Importance, Economic, or Cultural extensions. For example, ix:5 will find worlds with Importance 5, cx:[8-F]??? will find worlds with Heterogeneity 8 or higher.

Specify remark: to search for remarks/codes. For example, remark:Hi will find high-population worlds.

Specify in: to restrict search to workds in a sector. For example, uwp:*-f in:Deneb will find tech level 15 worlds in Deneb sector.

Specify like: to find similar-sounding words. For example, like:caboodle will find Capital.

Specify exact: to find exact matches. For example, exact:sol will find Sol subsector, but not the Solomani Rim sector. You can also surround a word or multiple words in quotes like "Nova Terra" to require an exact match.

Specify world , subsector or sector to restrict searches to just that type of result. For example solo sector will find only the Solomani Rim sector.

Multiple words form an "and" search. For example, sol ri will find the Solomani Rim sector, but not the Sol subsector. c* uwp:*-f will find all worlds starting with C that are tech level 15.

As a special case, searching for sector hex will find a specific world if present, e.g. Vland 1717 or SPIN 1910 .

Keyboard Controls

How it works.

The map page is a Web application built using HTML, CSS and JavaScript. The page uses script to request image tiles from the server. As the map is moved, more tiles are fetched from the server, filling in the edges of the map.

The server providing the map tiles is running Microsoft's IIS with a custom image generation service implemented in C# using ASP.NET and GDI+ to render the tiles as bitmaps. Maps can also be generated in PDF format (via PDFsharp ) or SVG for print-quality use.

The full source code to the site - both client and server - is available on GitHub and is released under the Apache open source license .

The map data comes from two sources. The macro-scale data - comprising the governmental borders and rifts is based on classic publications such as the Imperium Map poster released by GDW in the early 1980s. The micro-scale data is derived from sector data in ".sec" format . Official data from the Traveller 5 Second Survey effort is used where available.

Most of the data that allows the site to function is exposed by various APIs over HTTP and can be used by other sites and applications. See the API Documentation for more details.

Design Notes

The aspect ratio of the map follows the Classic Traveller convention of hexagonal parsecs, so parsecs are cos(30°):1 rather than square. This means that the map on this site matches the Classic Traveller resources such as the Imperium Map, maps in the Alien Modules, the Spinward Marches and Solomani Rim modules, and hexagonal subsector maps. Maps that use squares for parsecs, such as the Atlas of the Imperium or MegaTraveller -era publications, may appear distorted in comparison.

When zoomed out to larger scales, the stars are rendered pseudo-randomly rather than trying to display the actual system data. This maintains the appearance of the Imperium Map poster. Rifts are simply left empty. Zooming out further, rifts details from Mike Mikesh from Security Leak fanzine are used, and at extremely large scales the structure of Milky Way galaxy is represented using an illustration by Robert Hurt ( SSC ), JPL-Caltech , NASA , circa 2005.

History and More

This site was inspired by many sources, most prominently some of the treasured posessions from my childhood: the Imperium Map poster which provided an overview of Charted Space in the Classic Traveller era; the Spinward Marches poster included with Deluxe Traveller ; and the Atlas of the Imperium , which provided cursory maps of all sectors of the Third Imperium. In the early 1980's, using these and the classic Alien Modules, I carefully pieced together a map of known space on paper . I also dutifully entered the Sector Generator BASIC program into my Apple II and spent endless hours trying to coax a decent map from a dot-matrix printer .

In early 2005, after a hiatus from Traveller of nearly 20 years, I purchased a copy of the GURPS Traveller rulebook, which includes a map of charted space within the frame of an imaginary computer-based map viewer . I first saw this within weeks of Google Maps appearing, and was inspired to create a functional version of the map viewer using contemporary Web technologies. I was also inspired by the many other online Traveller map resources and desktop applications such as Jim Vassilakos' venerable Galactic .

Starting in 2013, this site began hosting the official data files of the Traveller 5 Second Survey effort, as well as older published data and unofficial fan submissions.

Information on the traveller rpg and its official setting, the third imperium..

We’re not the only ship on the mains!  Since its introduction in 1977, the Traveller universe has been developed in RPGs, computer games, novels and board games.  There are a lot of great resources for learning more about the Third Imperium.  Here’s just a few:

Far Future Enterprises is run by Marc Miller, the original author and creator of Traveller.

The Citizens of the Imperium is the largest Traveller community on the internet, and a great place to learn more about the game and its official setting, The Third Imperium

An excellent resource compiled and maintained by Joshua Bell, the Traveller Map is the easiest way to navigate the Third Imperium. There's no better way to appreciate the scale of Traveller.

Mongoose Publishing produces a flexible and popular version of the Traveller rules set, and their "Third Imperium" product line further expands the official universe.

The Imperial Encyclopedia is a wiki-style compilation of Traveller information. Articles are submitted and maintained by individual users, and cover both the official canonical universe as well as alternate setting or unofficial materials.

The Freelance Traveller Magazine is a long running, bi-monthly fanzine. Each issue features excellent articles on a wide variety of subjects, alternate rules, new settings and product reviews.

Looking at all the different versions of Traveller

I’m writing this article to help players and Referees new to the game who are looking for a bit of clarity and wayfinding. When I came back to Traveller to play, the GURPS version was live and detail-heavy supplements were hitting the shelves every month. Even then it was difficult for me to parse through the different versions of what had come before. So. Many. Versions. And now there are a handful more. That’s a lot of material out there. 

There are nine distinct published versions of Traveller out there in the wild that have come to us over time. Each one reflects a different riff on some fundamental ideas, a different interpretation of the game and setting by the authors. Perhaps details the Third Imperium setting in a different region of\r point in time, or maps to a different system of mechanics. Each version has a core rulebook and supplements that go with it to detail its particular universe.

Throughout the versions and over time, some aspects remain the same – characters developed with career terms, the idea of jump drives and that Age of Sail feel, the relative lack of transhumanism, the presence of various “mini-games” such as character/world/ship creation within the rules that are playable by a single person are all aspects common to all versions.

Let’s survey the different versions:

Classic Traveller ( CT )

This was the first edition developed in 1977 by a small outfit in Normal, IL called Game Designers Workshop, and it was the first sci-fi roleplaying game and a contemporary of the first version of Dungeons & Dragons. Classic Traveller was published in the characteristic “Little Black Books” ( LBBs ) and first detailed a “sandbox” style rules system as a toolset for Referees to create their own settings and subsections. Not long after the initial offering the system was expanded in every way, and the default setting of the Third Imperium in the game-year of 1105 was developed. CT continued to be published, revised, and expanded for nine years. A profound amount of supplemental expansion material was published for CT. This version has many active fans to this day, a reflection of perhaps the well-designed rules or the idea of legacy; we tend to stick with the version of the game we were introduced to.

MegaTraveller ( MT )

Almost ten years after the initial offering, the first truly new version ( there had been several incremental upgrades to CT before this ) came along with a new task system, expanded setting materials, and an advancement on the default setting timeline. The game mechanics were now very much interwoven with the Third Imperium setting, where it was now 1116 and the Emperor had been assassinated. Principal play and supplements all detailed a collapsing Third Imperium rife with Rebellion. MegaTraveller was set in an expansive area; most of the Third Imperium as it collapsed, and ran as a published game for five years.

Traveller: A New Era ( TNE )

In 1992, just five years after it’s predecessor MT, Traveller: The New Era hit the shelves. This game featured an entirely new mechanics system and was also strongly interwoven with the default setting, which had been advanced more than a hundred game-years to 1200. These mechanics are for the most part incompatible with other editions of Traveller. In TNE the Third Imperium is gone, shattered, to be replaced by chaos and barely-forming order within Charted Space. TNE also introduces the existential threat of “The Virus,” a digital phage-like AI that threatens to wipe out an civilization it comes into contact with. The default region of play is the former Domain of Deneb. TNE published materials and expansions for three years.

Marc Miller’s Traveller ( T4 )

Four years after the introduction of TNE, the original publishing company had folded and the original creator Marc Miller published a new version of the game from Imperium Games. This version uses an updated version of the mechanics featured in MegaTraveller. As a default setting, the clock is dialed backwards now to the first years of the Third Imperium, where the Sylea Federation gave birth to the new empire. Players participate in the expansion of the new Third Imperium, re-connecting with various “pocket empires” after The Long Night after the collapse of the Second Imperium. The default sector of play was Core, and this version ran for two years.

GURPS Traveller ( GT )

Published by Steve Jackson Games in 1998 and based on the GURPS mechanics and ruleset, this version was imagined and driven by GDW alum Loren Wiseman. The setting was a re-imagined Third Imperium in the year 1116, but in this version Emperor Strephon was not assassinated and the Rebellion never happened; the “original” CT timeline was simply advanced and The Rebellion and The Virus never occurred. The GT default setting within the Third Imperium was the Spinward Marches sector, although additional materials also developed the Solomani Rim. GURPS Traveller published new material until its license expired after 6 years. SJG supported its version with a wealth of supplemental material and although the GURPS  system certainly has its advocates, in Traveller circles more people seem to be fan of the GURPS books as source material, supporting their game based on non-GURPS mechanics.

Traveller D20 ( T20 )

In 2002 a Traveller version with game system mechanics compatible with the extremely popular d20 system was published by QuikLink Interactive. The default setting detailed Gateway Domain near the Solomani Rim of the Third Imperium at the game-year 1000, a little more than 100 years before the events comprising the CT setting. T20 was the first version concurrently “live” with another Traveller system ( GT ) and was published for six years. T20 supplements were written to be compatible with CT material and settings, and an extensive amount of works were published.

Traveller Hero ( TH )

In 2006 ( and concurrent with T20 ) a version of Traveller utilizing the mechanics from Hero Games Star Hero was published by ComStar Games. A distinction is the use of a pool of points with which to build characters, roughly similar to GURPS. All of the various settings/times covered in prior versions of Traveller with the exception of the CT milieu were embraced by HT. This version was published for two years.

Mongoose Traveller ( MgT )

Live version – In 2008 Mongoose Publishing produced a “reboot” version largely informed by Classic Traveller. The default setting was the Third Imperium in 1105, though the mechanics were intentionally set apart and offered as a way to portray play in various non-Third Imperium scoff settings. MgT is published today ( in 2017 ) though now in its second edition after eight years, and features an expansive portfolio of supplements and supporting material.

Traveller5 ( T5 )

Live version – In 2013 Marc Miller ( through Far Future Enterprises ) published the “ultimate” version, comprised completely of a profoundly expanded mechanics/ruleset without a core default milieu but comparable with all prior published Traveller milieus. T5 is also a “live” version. At present there is a single seriously-dense 700+pp volume, and no supplements or expansions. Both fans and detractors cite the incredible complexity of the material as a reason for their fervor.

Traveller generators: worlds, systems, sectors, subsectors, and Mongoose 2e characters

I’ve posted about Traveller generators before here on Yore, but I’ve also used one or two I’ve never posted about — and recently found a great Reddit list of even more generators that were new to me. Time for a round-up!

My brain is in Mongoose Traveller 2e [ paid link ] mode at the moment, but given the broad compatibility of the various editions of Traveller — especially in terms of setting creation — these generators should be useful no matter which flavor/fork appeals to you. The only exception is the last one on the list, which specifically creates Mongoose 2e NPCs.

Sectors and subsectors you can revisit, with maps

The inimitable Alex Schroeder offers a triple threat for Traveller GMs , with some really cool features. The main Traveller generator page features links to generate random sectors and subsectors; those output on a new page, with a unique URL. (To generate a new one, you have to hit the link on the main page. Refreshing your generated page, logically enough, changes nothing.)

You can also paste in your own list of UWPs (and the list the page itself generates is preformatted to work perfectly here), or the URL of a page you just generated, and then hit the “Submit” button, and the site will also generate your subsector or sector map. (The map needs to be saved locally for future use.)

Systems, sectors, and subsectors, with options (rift, spiral arm, etc.)

If you want some options when it comes to type of sector/subsector, neuzd’s awesome Mongoose 1e generator is a one-stop shop, and includes options for rift, sparse, spiral arm, and densely populated sectors and subsectors. Those options are what make this one so cool. Do note that you can’t bookmark the results; you’ll need to export or paste them for future use.

Best of all, you can select the type of sector/subsector with this generator, copy the resulting list, paste it into Alex Schroeder’s generator (above), and the latter will create your map for you. The best of both worlds!

Systems and worlds with bells and whistles

One of my go-to sites for generators of all stripes, donjon , offers an amazing system generator that includes planetary images, a breakdown of the system, and a full work-up of the core world that includes a randomly generated world map. For a new system, just hit refresh. The simplest way I’ve found to preserve its output is to take a screenshot.

Worlds you can revisit

The PBE Games world generator is fantastic. It will spit out random worlds, of course, but you can also provide your own UWPs and it will expand them into full write-ups. Best of all, the generator provides a seed for every world it creates — just save that seed (a short string of characters), and you can plug it back into the generator anytime to re-create that world.

Worlds based on milieu, with extras

Not only can you specify the milieu and other details before generation, Traveller Tools will also tell you fun stats like refuel time, travel times and distances, and available trade goods. This one appears to be Mongoose 2e-specific (to the extent that that matters). A permalink is available for every world you create.

Mongoose 2e Traveller character generator

Traveller Tools also features a great Mongoose 2e Traveller character generator, and there’s a permalink for any character you create. You can specify age and careers or just let the randomizer do its work; either way, it’s intended for NPCs and, as the page notes, takes a few liberties with the rules to enable random generation.

Mongoose 2e characters aren’t quite as simple as OG Trav characters (which generally fit into a line or two of text), so I was thrilled to find this one.

The Zhodani Base offers a beefy list of Traveller generators covering everything from sectors to counters to magazine covers. There’s plenty here that should be handy for any Trav GM.

Thanks for posting Its nice to see a synopsis of useful Traveller materials and website

You’re welcome! There’s so much cool Trav stuff out there.
