🌍 Town & World Simulation
Configurable rates for birth, death, conflict, and relationship formation. Run 0–24 months per pass; preview changes before applying.
EON WEAVER
Your setting keeps moving—even when the table is quiet.
Months roll forward across towns: demographics, drama, and macro-scale change—tied to an in-game calendar and real geography on your world map (pins, travel—not just a relationship chart).

HOW IT WORKS
From empty world to living campaign in four steps.
-
1
Build your towns & world
Add settlements, set demographics & rules per town, upload your world map, and drop pins on the locations that matter to your party.
-
2
Run a month between sessions
Simulate one town or every settlement in a single pass. Births, arrivals, departures, relationships, drama, and the occasional disaster—all configurable.
-
3
Anchor everything to the calendar
Every event lands on a real campaign date. Hook plots to specific moons, festivals, or seasons your players already recognize.
-
4
Keep the lore current
The AI scribe writes wiki entries from the events that just happened, so your codex grows with the campaign instead of after it.
FEATURES
A campaign manager, a world simulator, and a lore engine.
🗺️ Geographic World Maps
Upload your own map, place pins for towns and landmarks, and estimate travel distance and duration between any two points.
📅 In-Game Calendar
Custom calendar config. Advance days, weeks, or months. Sims and plot hooks tie back to campaign dates automatically.
📜 AI Scribe & Wiki
Auto-generate town histories, NPC bios, and recap entries. Searchable, editable wiki you can share with your table.
🧙 Characters & Level-Up
Full character sheets plus a guided level-up wizard (3.5e most complete). Roster import from statblocks.
⚔️ Encounters
Build encounters from your roster and the SRD; track combat state in a dedicated view.
🎮 VTT Export
Export rosters and characters in formats your virtual tabletop can read.
👥 Player Portal
Optional read-only view your players can bookmark—just the lore and campaign info you choose to share.
💬 Discord Integration
Deploy notices, scribe pings, and bug reports route to your Discord. Optional and configurable.
EDITIONS
Built around 3.5e. Friendly to the rest.
Eon Weaver's roster, sim, calendar, and scribe are edition-agnostic. The character sheet and level-up wizard go deepest on 3.5e today; other editions are usable now and growing.

Built for the DM running long campaigns.
“Your setting keeps moving—even when the table is quiet.”
- You run a campaign that's been going for years and you're tired of the world standing still between sessions.
- You want demographics, drama, and macro-scale change without writing every NPC's life by hand.
- You care about real geography—where places are and how long it takes to get between them—not just a relationship chart.
- You have more lore in your head than time to write down, and you want an AI scribe that catches up for you.
