These are the core rules for the L5R RPG. From the introduction: Welcome to Rokugan, the Emerald Empire(TM). Rokugan is a place of mystery and wonder, inspired by the legends of feudal Japan and other places in the far East. It's a world of samurai and ninja and spellcasting shugenja, where dragons soar the skies and danger lurks in every shadow. The Legend of the Five Rings Role-Playing Game (L5R RPG) allows you to take the role of one of those legendary figures in search of honor, glory, and adventure.
