Novarrium for Game Masters
Your Campaign World, Kept Straight Between Sessions
Map it, people it, lock the lore. Then write handouts, histories and recaps that never contradict what your players already know.

Every game master has lived it: an NPC whose eye color changed between sessions, a town that moved across the river, a rule you improvised in week three that nobody wrote down. Novarrium keeps your world in one place and treats what you have decided as law. The map, the cast and the lore are the source of truth, and anything a language model drafts for you is checked against them before you see it.
The consistency problem
NPCs Drift
The innkeeper was a half-orc with a scar in session two. By session nine your notes, and your memory, disagree.
Lore Lives in Ten Places
A wiki, a notebook, three documents and a Discord thread. Nobody, including you, knows which one is current.
Things Change and the Notes Do Not
The duke died in session twelve. Half your prep still treats him as alive.
What Novarrium does about it
A Map You Draw
Hand-drawn ink map themes, a land tool that raises coastlines from a stroke, stamps for mountains, forests and lakes, your own custom stamps, and labels that follow a path.
NPCs With Locked Traits
Pick hair, build, face, outfit and more when you create a character. Those picks become fixed facts that anything written in your world must respect.
Facts That Change on Schedule
Record that something changed at a given point: the duke dies, the bridge falls. Anything written for earlier in the story keeps the old truth, anything later gets the new one.
World Rules That Hold
Write the rules of your setting once ("no resurrection magic"). Generated writing is checked against them, and a violation is repaired or flagged for you.
Straight answers
Is this a virtual tabletop?
No. There are no dice, tokens or initiative trackers. Novarrium is where your world lives between sessions: the map, the cast, the lore, and writing that stays consistent with all three.
What can I write with it?
Anything that reads as prose: session recaps, in-world histories, legends, letters and handouts. The writing is organized in chapters, and every one is checked against your locked facts and world rules.
Can I bring in lore I already wrote?
Yes, if it is written as prose. Import it and Novarrium extracts the characters, places and facts into your Story Bible, where you can review and lock them.
