Armed with the knowledge of the Spirit Realms, you’ll be ready to embark on the Wheel of Judgment adventure—a Legend of the Five Rings Roleplaying adventure designed specifically for deceased PCs. From Meido, the Realm of Waiting, you and your fellow samurai face a journey unlike any other, leading you across the realms to hunt down the corrupting influence of Jigoku… and perhaps, if you’re lucky, to return alive to Ningen-dō.
