Kelarthianism is a native religion of Lacertia, established as a cult of personality by Kelarth the Conqueror.
Kelarth the Conqueror was viewed during his lifetime as a living ancestor. His actions and ability to unify the clans were seen as so great that he was venerated as though he was already a spirit, essentially acting as a god among mortals. He is also believed to be the bridge between mortals and spirits, and may commune with them in a much clearer and straight forward way than others, including the priests who train specifically for this duty.
Priests, who are always females, serve to interpret any warnings from the ancestors. They are not allowed to marry and take oaths of celibacy. As well as religious service, they also record history, act as judges, and raise all the children of all the clans until they reach age 12, during which time males undertake their trials and females go and learn their craft. Children spend all their time raised by the priests except for a two-week celebration each year, which they spend with their families. However, families may visit their children any day when the child is not being culturally educated.
After the conquest of Lacertia by Ashenia, the worship of Kelarth was heavily discouraged. The populace is currently disunited in regards to his status, with some viewing him as a martyr and others decrying him for his inability to protect the land from foreign invaders. There is even a small movement, deemed heretical by almost all Lacertians, that revere the monarchs of Ashenia as they were able to triumph over the living god that was Kelarth.
