This religion has it's roots in the travelers who first set foot on Craphis, back when it was known by a different name. It has subsequently evolved to be the backbone of the Craphishian Monarchy.

Castism teaches to follow Casieo (God) and submit and die for the leader he blessed to have the divine right to lead Craphis. It also teaches Nationalism and teaches people to realize that Craphishians are the superior race and must colonize and conquer every other planet and exterminate inferior races and species who get in the way. Other teachings are themes of self-pride and believing that you are the best, tradition first, expansion over environment, only invest in yourself and your best interests, use power to control others, etc.

Worship happens in a state-approved Royal Castist Church.

February 5th celebrates the day that the KOC led the final strike on the DCU army, defeating them and taking out their leader the very same day. This holiday is remembered greatly as the DCU was the last opposition to KOC rule.
