"One player. One world. Vows that cannot be broken."
Ironsworn is THE dark fantasy solo RPG. Free, complete, uncompromising. Play alone, co-op with a GM, or fully GM-less — the same rules support all three modes. Inspired by Powered by the Apocalypse: moves, not rules — narrative always first. Oracles generate the world, threats, and unexpected twists right at the table. Zero prep. Just vows, stakes, and iron.
The Ironlands — a grim, hostile north. Not heroic fantasy with dragons and taverns — here people cling to survival at the edge of a scorched world. Clans, feuds, dark forests, forgotten ruins. Inspiration: Norse myth, Celtic melancholy, and the feeling of a besieged frontier. Every quest isn't 'save the world' — it's 'survive. Fulfill the vow. Die with honor.'
Iron Vows
Every quest begins with a sworn vow on iron. A progress track shows how far you've come. Breaking a vow means losing part of yourself.
Three play modes
Full solo (you and the oracles), co-op GM-less (everyone shapes the narrative together), or classic with a GM. One ruleset — three distinct experiences.
Oracles & the Fates
Tables for random events, NPCs, threats, and places stand in for a GM. Ask a question — roll the dice — interpret. The world builds itself.
PbtA-style moves
No rule for every situation — only moves. Face danger, undertake an expedition, aid an ally. Failures earn experience. Successes raise the stakes.
