Player's Guide to Kaidan
A Pathfinder roleplaying setting inspired by Japanese history and folklore, Kaidan is a cursed archipelago where restless dead, powerful undead rulers, oppressive samurai, demons, and shapeshifting creatures shape everyday life. The guide presents the region’s history, people, religions, and cycle of death and rebirth, along with player options including humans, yokai, koropokkuru, kappa, and kitsune. It also introduces the Necrotic Warrior class, which channels negative energy in combat, and provides the setting details needed for adventures involving dark magic and horror.
