The basic faith of Celestialism is a faith in the 15 gods of the pantheon. The worship practices for these gods – their holy days, rites, and prayer services – is standardized in the Holy Episcopate’s capital of Silverstream. These forms of worship are used throughout Orthon.
According to Celestialist dogma, these deities are the only true gods. There are no beings above them, and there are no other beings worthy of worship. This is not to deny the demonstrable fact that there are clerics who profess the faiths of non-Celestial gods. However, according to Celestialism, these faiths are mere cults, following false idols that do not have true universal power.
This is the official belief of Celestialism according to the Archbishops. However, outside the Holy Episcopate’s territory, people generally don’t see anything wrong with venerating other gods outside the Celestial pantheon, as long as they aren’t evil gods. People in the Empire of Gard and Dragonfall often worship the Ascendants right along with the Celestial gods, for example.
The leader of Celestialism is the Celestial Archbishop. He is also the head of state in the Holy Episcopate. This dual role as both religious and secular leader causes great tension between the Holy Episcopate and the Empire of Gard.
