Codex Cryptica is an AI-assisted worldbuilding and campaign management tool built around a living knowledge graph instead of a folder of loose documents. Every character, faction, location, and event you create becomes a linked entity, so your world stays connected and explorable as it grows. Genre-agnostic across fantasy, sci-fi, cyberpunk, horror, post-apocalyptic, western, steampunk, and more.

StarCar is a permanently free linear star systems cartography tool. It enables GMs running sci-fi campaigns to visualize and share star maps with their players easily. It allows a lot of different customizations for orbital bodies, like planets, secondary stars, Ringworlds, Dyson Spheres, and more. GMs can add notes to individual orbital bodies, stars, and moons. The notes can be totally customizable, or use either Traveller or Stars Without Number rules. If they want, the GM can even export a stylized PDF report that details all the notes in an easy-to-follow format. And if the GM just needs something right away? StarCar will roll the dice and generate a totally randomized system: random stars, planets, and even randomized plot hooks. Once the GM is finished, they can export it in a number of different formats: PNG, WebP, or JPG, or with settings like Printer Friendly or Transparent Background. Anything exported is licensed under Creative Commons 4.0, which means the person who makes it owns it. They can even use it in any products they sell, with attribution.

Nav-Fi³ is a web-based campaign companion for the Traveller RPG, covering both the classic Third Imperium setting and Mongoose's 2300AD. Run your ship like a real operation: a time-aware financial ledger tracks income, costs, mortgages, and crew payroll against each vessel's account, with automatic PENDING/POSTED transitions synced to your campaign's calendar. Plot jump routes on an interactive TravellerMap-integrated navigator, manage cargo holds and speculative trade, and let The Cube (or 2300AD's The Link) generate freight, passenger, mail, salvage, and prize contracts on demand. Multi-user by design: a Referee can grant players granular access to piloting, cargo, or finance on a per-ship basis, suspend and reinstate them without touching the roster, and everyone logs in with Google or Discord (2FA supported). Crew records track status over time — active, MIA, deceased — and every session's changes surface in an automatic "Since Last Session" recap. Two settings, one interface: pick Traveller (with full Milieu/era support) or 2300AD (Gregorian calendar, Stutterwarp drives, colonial nations) from the sidebar — same tool, faithfully adapted rules underneath.

Hail Adventurer well met! Stockholm D&D is an 18+ community arranging recurring D&D sessions at one of the friendly local gaming stores in Stockholm. We have been arranging sessions in a persistent shared universe using D&D 5e since 2019. We are transitioning to D&D 5.5e in 2026. Whether you are a complete beginner or a seasoned veteran, players and Dungeon Masters are welcome to join “The Guild” and adventure across the worlds of D&D. The thread that ties all the characters together is “The Guild”, a trans-planar organisation offering the service of adventuring parties to those in need. “The Guild” allows player characters from any plane to team up and do the good work of “The Guild” in whatever world the Dungeon Master wishes to run the adventure in. Play begins at level 3 with each session played earning you half a level, meaning you'll level up every other session. We administer our events, sessions and characters through a Discord server where detailed rules about supported sources for character creation etc. are presented. Links facebook.com - Facebook page
