The largest and most organized religion in Telgard is the Church of Telgard, who worship the Dargotten pantheon. They have a foothold in every kingdom save for Tahnn, while versions of the religion are followed by at least 55% of the population of Garr and 95% of the populations of Lirynn and Korresh.

All other beliefs are deemed heretical by the Church of Telgard, with each belief resting on a varying scale ranging from "Not so bad, barely tolerable" to "Mighty Dargotten, strengthen my arm so that I might smite thine enemies!"
