Sigmism

Sigmism is a syncretic religion that centers around the worship of a Supreme Demonic God named SIGMA. It combines elements of Hermetic Philosophy with the study of ancient demonology.

Warner Sigmism
The occult philosopher and spiritualist Thomas Warner developed a slightly altered version of Sigmism in his latter days. As opposed to the traditional view of SIGMA as an entity with human characteristics, he instead viewed SIGMA as an energy-like force that imparted power and knowledge to chosen followers of his cause. Warner believed that in order to become a candidate for selection, one would have to undergo a ritualistic cleansing rite known as Salkfe, which would impart "true wisdom and peace" upon those who underwent the rite. The subject of the ritual would be forced to give up their soul in exchange, creating an Exanimus.
