Kaidan—whose very name means "ghost story" in Japanese—is a mist-shrouded realm of exotic races, oni demons, and yurei ghosts, ruled by an undying imperial court enforced by ruthless samurai with all social castes bound to an endless cycle of twisted reincarnation. The empire of Kaidan is, by definition, haunted. Included in this tome are 30 haunts and several unique and horrifying undead variants, all inspired by classic Japanese ghost stories.
This volume is organized in nine creepy storylines to help you envision the horrors that await your adventuring party in the dark realm of Kaidan. Brought to you by T.H. Gulliver, the same designer that brought you the award-winning #30 Haunts for Objects (DieHard GameFan's best supplement for 2011). This product brings something to the game it has never had before, haunts that are embeded in the very nature of the realm.
I enthusiastically agree with everything Endzeitgeist said in his review. The whole Haunts series is very well done, but this is the very best of the lot with its story thread of creeping horror running through it all. It also serves as a nice reminder of how even the weakest fiends can be used to cause a ton of trouble. And it just feels so 'Kaidan'.
