System generation, charting, and campaign management for Traveller Referees.
My Traveller Universe is for Traveller Referees running homebrew campaigns, exploration campaigns, or campaigns set on the uncharted fringes of Charted Space. Generate star systems, map subsectors and sectors, maintain survey records, and export campaign data for use in external applications like Obsidian and Foundry Virtual Tabletop.
Generate systems from configurable rules.
Create single systems or entire subsectors from a build configuration. You can create systems by hand or leverage My Traveller Universe to generate systems using the rules in the World Builder's Handbook from Mongoose Publishing.
- World Builder’s Handbook based generation
- Build configurations for density, stars, worlds, and rogue objects
- Optionally derive a build from existing survey data
- Edit UWP, trade codes, populations, governments, tech levels, and Bases
Start simple with the subsector density and who has settled it.

Map systems, subsectors, and sectors.
Maps are generated from the campaign data itself. A system map, subsector map, sector map, and print-ready poster can all describe the same underlying survey records.
- System, subsector, sector, and poster maps
- Jump routes, travel planning, regions, and route networks
- Allegiance territories, travel zones, system names, hex codes, and UWP strings
- Export maps as SVG, PNG, WebP, or PDF
Imported star system, with both referee and player pages.

Use the data outside the web app.
Campaign data can be exported as Markdown for Obsidian, or used in Foundry VTT through the My Travller Universe Foundry module. The web app can remain the system of record while other tools receive the records needed for prep and play.
- Markdown exports
- Foundry VTT integration through the MTU module
- Separate player and GM views
- Campaign data remains editable in one place
Exploration campaigns.
Subsector data can be imported directly from travellermap.com, or generated from predefined build configurations based on the Deepnight Revelation campaign books. As the revelation travels, system details can be revealed to the players.
