Cosmic Horror Worldbuilding & Setting Management
Codex Cryptica for Cosmic Horror
Keep occult orders, research archives, expedition logs, and incomprehensible entities connected in one local-first workspace.
Why worlds get complicated
Cosmic horror mysteries rarely reveal themselves in a straight line. A symbol found in session two turns out to belong to the research group mentioned six sessions later; an expedition log contradicts an official report; an NPC who seemed like a footnote is the only living person who has seen the same phenomenon. Codex Cryptica keeps those connections visible as the mystery grows so you always know what has been uncovered — and what is still waiting in the dark.
