The worldbuilding engine authors trust, now with tools built for Game Masters. Session prep, continuity tracking, and world management that scales from a one-shot to a multi-year epic campaign. Not a VTT -- the best prep tool you've ever used.
Foundry, Roll20, and Fantasy Grounds own the live-play space. Edda owns prep, continuity, and recap. They complement each other perfectly.
Campaign Mode uses the same deep worldbuilding tools that novelists use to manage continuity across 100,000-word series. Your campaign gets that same level of organizational power.
Define recurring world events with configurable intervals and variance. Highstorms every 4.5 days with 1-day variance? A full moon every 28 days? A Desolation that returns across ages? Cycles handle it all, linked to your custom calendar.
Nest eras within eras. The Third Age contains the War of the Ring contains the Quest of Erebor. Each era can have its own calendar, its own cycles, and its own scoped events. Timeline views group events by era with visual boundaries.
Set a scene 50 years before a character was born? Reference a city that hasn't been founded yet? Edda flags it automatically. No more flipping through notebooks to verify your timeline. The continuity engine checks character birthdays, lifespans, and location founding dates against every scene.
Give a scene an in-world date and Edda tells you what's happening: which era is active, which cycles are firing, what conditions apply, and how old each character is. Context you'd normally look up in three different places, delivered automatically.
Full character profiles with 30+ fields, relationship maps, character arcs, family trees, and gallery support. Track every NPC your party has ever met -- their motivations, secrets, connections, and the scenes where they appeared.
Build calendar systems with any number of months, weekdays, and holidays. Track moons, define leap year rules, and place events against a timeline that belongs to your world. Add cycles for weather patterns, magical phenomena, or political events that recur on a schedule.
Nested location hierarchies (continent > kingdom > city > district > building > room), interactive map pins, encyclopedia articles for lore, and everything cross-linked. Your world bible is always one search away.
Use Ollama for completely private, offline AI assistance -- generate NPC descriptions, brainstorm plot hooks, check consistency, or expand session notes. Or connect OpenAI/Claude for cloud-powered assistance. Your choice, your data.
