Tracks change when the dice land.
Journal
The Havens are three days behind you. Rain has been falling since the pass, and the track you were following gave out an hour ago against a wall of black spruce. Somewhere ahead, past the treeline, a bell is ringing — slow, uneven, the way a bell rings when nobody is pulling the rope on purpose.
The sound comes from a steading you were told had been empty for two winters. Smoke, thin and grey, threads up through the rain. You can go in past the gate like a guest, or you can go around and see what the gate is hiding.
What do you do?
Rolls use the same engine as real play
Living Codex
Names, places, and consequences are written here as the story unfolds.
The Narrator can't contradict the Codex. That's why it doesn't forget.
Your next choice changes the sheet, the journal, and what the narrator is allowed to say.
How it plays

No prep, no GM, no waiting. Open a Free Adventure and the Ironlands write themselves around you — grounded in honest dice and a sheet that updates itself.
Free Adventure

No script. Swear your own oaths and let the oracles, the dice and an AI narrator carry the saga wherever it goes. Truths are seeded at the start, scenes follow your moves, and every twist is written into the journal.
- AI narration grounded in your sheet & dice
- Multi-session campaigns with persistent memory
- Begin in minutes — no prep required
Oracles, instant
Every Ironsworn oracle at your fingertips. Tap, roll — the answer drops straight into your journal, timestamped and sourced.
A sheet that updates itself
Momentum, tracks, conditions, vows — every roll and every choice writes back to the sheet. No bookkeeping.
Your saga, preserved
Narration, dice and scene transitions stitched into one chronicle. Export as Markdown or a bound PDF.
The edge
Engineered, not prompted.
Anyone can slap a system prompt on the strongest LLM. Markbound is a TTRPG engine the narrator runs inside — dice in code, memory in the database, canon sealed before play begins. The price covers that engineering, not just the API call.
Honest dice
Rolled in code with crypto-grade randomness, in your browser. The narrator describes the outcome the dice already produced — it never decides one.
Living Codex
Every NPC, item, location and threat is tracked in a structured ledger across every turn. The narrator can't forget who died last session.
Bible-as-canon
Your saga's setting, NPCs and vows are sealed before play. If the player names something that isn't canon, the narrator redirects — it can't quietly invent a sister you never had.
Length-validated
Zero NPC or setting contradictions across 137 turns of independently judged play. Personality drift cut 7× vs the prior baseline.
Plain talk
Why not just use ChatGPT?
You can. We did, for a long time. Then we built this.
The dice are honest. The story is yours.
