FIND THE RING OF THE SEA WIZARD'S BRIDE. STOP THE RITUAL. SAVE THE KNOWN WORLD!

Twelve Years at Sea is the long-awaited epic seafaring expansion for Twelve Years, drawing inspiration from the weird fiction masters, ancient mythology, and the monster-filled spectacles of Ray Harryhausen's legendary films. This is maritime adventure at its most fantastical—where crews battle krakens beneath new stars, explore strange islands, and face the thrill of endless, uncharted waters.

Twelve Years is a GM-less 'solo+' RPG system, designed to be played solo or with other players. It blends prompts, emergent storytelling, and striking visuals into a rich narrative experience that can be replayed again and again and again.
