Space Opera Worldbuilding
Codex Cryptica for Space Opera
Keep star systems, worlds, governments, factions, crews, and trade routes connected across your galaxy.
Why fantasy worlds get complicated
Space opera campaigns span dozens of systems, rival governments, criminal syndicates, and a crew's tangled web of contacts and enemies. When your players reach a new sector, you shouldn't have to reconstruct who controls it, who they owe favours to, and what's already gone wrong there.
Why Codex Cryptica?
Star Systems, Worlds & Orbital Locations
Map star systems down to individual worlds, moons, stations, and orbital hazards, all linked to the sectors they sit in.
Governments, Factions & Rival Powers
Track empires, republics, corporations, rebel movements, and criminal organisations competing across your setting.
Crews, Contacts & Adversaries
Connect your crew, patrons, informants, rivals, and bounty hunters using a visual relationship graph.
Routes, Borders & Conflict
Chart major routes, contested systems, blockades, and the political relationships that shape travel across your setting.
