How It Works
SOJEN helps you build comprehensive dungeon lore through structured world-building. Create entities for dungeon denizens, ancient artifacts, and forgotten deities. Develop canon entries that explain the dungeon's creation, fall, and current state. Organize your underground mysteries into timelines that track the rise and fall of civilizations. Generate detailed codex documents that serve as dungeon master references, complete with images of key locations and creatures. Connect dungeon entities to canon events to show how ancient curses, magical catastrophes, or political intrigue shaped each level. Your dungeon becomes a living story world with depth that players can discover layer by layer.
