Two turns, no account
This is the actual play screen in miniature, running the same dice engine as a live saga. Nothing here is scripted to succeed — roll badly and you'll feel it on the track.

The sheet updates itself from the roll — you never bookkeep.
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.
Rolls use the same engine as real play
Living Codex
Empty. Make a move — anything the story names gets written here, and stays there for the rest of the saga.
The Narrator can't contradict the Codex. That's why it doesn't forget.

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
Available nowNo 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.
Every Ironsworn oracle at your fingertips. Tap, roll — the answer drops straight into your journal, timestamped and sourced.
Momentum, tracks, conditions, vows — every roll and every choice writes back to the sheet. No bookkeeping.
Narration, dice and scene transitions stitched into one chronicle. Export as Markdown or a bound PDF.
The edge
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.
Rolled in code with crypto-grade randomness, in your browser. The narrator describes the outcome the dice already produced — it never decides one.
Every NPC, item, location and threat is tracked in a structured ledger across every turn. The narrator can't forget who died last session.
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.
Zero NPC or setting contradictions across 137 turns of independently judged play. Personality drift cut 7× vs the prior baseline.
Plain talk
You can. We did, for a long time. Then we built this.
The dice are honest. The story is yours.
