Daiyehism

Daiyehism is the religion worshiping Daiyeh, the God of Death, though his degree of true sentience is debated between branches of the religion. Although Daiyeh himself originates from the San-Tsi mythology, Daiyehism has a significantly different interpretation of the god.

Origins
Daiyehism was founded by Ma Yu during the reign of Emperor Huanzong. Ma Yu was originally a slave, but freed by her master, the philosopher Chongyang, who sensed her potential. She taught that, because the gods were immortal, only the god that dealt with mortality was important to mankind was the God of Death-- Daieyh.
