In contrast to the vast architectural design of Arcadia, Souhonzan is primarily made up of small buildings and earthen caves, while many of the priests wear clothing reminiscent of Shintoist garb. The population consists primarily of Gaian Priests. Doukan resides in a massive castle found at the back of the city, located at the top of a small mountain.
