The Coils of Ydersius is an organization dedicated to the serpentfolk demigod Ydersius. Although some believe that the god is dead, members of the cult are aware that he is not, although it is generally believed that he is divided into two sections: a skull-like head, and a still living body. They try to bring about his and the race of the serpentfolk's triumphant return onto the surface of Golarion. Some human followers believe that they are the reincarnated spirits of ancient serpentfolk, although it is unknown whether this is actually the case.[1]
