Established by a half-elf named Aun and her group of followers in 20 CE. The founding belief is that there is no set of divine beings and that the lands were shaped by ancient creatures of both water and land. After investigating the historical and archeological evidence of the lands, Aun came to conclusion that many of the stories from the other religions had inconsistencies with physical evidence. She made it her mission to travel the lands and spread the word about her discovery and gained a lot of support from those who felt abandoned by those that they served and dedicated their lives to.
As a non-theistic religion, those with a strong sense of faith typically just see followers of Aun as lost or naïve.
