Dantism

Dantism is a belief that focuses on Cosmic Pathology or the manipulation of Death through various means.

Etymology
Dantism comes from the name of the Embodiment of Hell, Daniel, and the Latin suffix isme.

Some translators believed Dantism to be related to the spirit Dantalion who possessed the great magician Brinno, but it was quickly debunked as said Magician claimed to have no connection to Dantism.
