The air in Kage no Shima is thick with the
scent of blood and the promise of violence.

The Land of the Endless Night, my friend, is a place of DARKNESS and FILTH.

Welcome to RŌNIN, a rules-lite tabletop RPG set in a mythical, samurai-inspired world. Based on the MÖRK BORG system, RŌNIN is a game of honour, combat, and adventure.

In a world ravaged by an eternal eclipse and overrun by supernatural creatures known as yōkai, players take on the roles of forgotten ronin, shinobi, onmyoji, and more as they seek to restore their honour and defeat the forces of darkness.

A richly detailed island that blends Edo Period Japan with fantasy elements, creating a unique and immersive world that is perfect for players of all levels.
