Traveller Companion

The Traveller Companion is the ultimate expansion for the Traveller science-fiction role-playing game, packed with optional rules, new systems, and powerful tools that let you customize your campaigns exactly the way you want. Designed to work seamlessly with the Traveller Core Rulebook, this supplement broadens every aspect of play: from character creation to starship operations and planetary exploration.

Inside you’ll find alternative lifepath rules, new backgrounds, expanded careers, additional combat options, and modular systems that let you fine-tune the game’s tone and level of detail. The book also includes guidelines for running harsher survival campaigns, political or espionage-focused adventures, and sandbox exploration across newly generated star systems.

Perfect for both referees and players, the Traveller Companion offers deeper customization, richer worldbuilding, and flexible mechanics that enhance any long-term campaign. An essential addition for anyone who wants more control, flavor, and variety in their Traveller universe.
