Pantheon of Jung
The largest religion in the Cosmos is the polytheistic faith of the Pantheon of Jung. Several similar polytheistic faiths developed on homeworlds thousands of years before the development of spaceflight. As the sentient species discovered each other, they found that they had remarkably similar myths and deities; this was taken as a sign of divine truth. The human philosopher Jung theorized that the faiths of various species were all reflections of the same deities, and organized the Pantheon using the traditional human names. It is taught that before the current Deities came to power, before Creation itself, there were eight extremely powerful Primordials who were overthrown by their servants.
The Pantheon consists of 24 major deities and 32 minor deities. Each major deity rules over a domain at the border of two Arcane Realms, and each minor deity rules a subdomain at the overlap of three Realms. Most people worship the entire pantheon, praying to specific deities as appropriate to their domain, but priests are typically devoted to a single deity. The more popular deities have large priesthoods and many temples throughout the cosmos, while most of the Death deities are served only by small cults. The churches (and deities) are usually closely allied with others that share two of the same Realms, and friendly with those that share one, and are unfriendly or enemies with those whose domains stem from opposing realms. Although the priesthoods of each deity are organized independently, there are regular councils and meetings between worshipers of the entire Pantheon.
Although belief in the Pantheon, or at least lip service to it, is the most common religion, it is not the only belief system in the Cosmos. Other faiths have small but devoted followings, and either proselytize or otherwise try to serve their faith throughout the Cosmos.
Atheists and Agnostics
Since some priests can clearly wield divine magical power, there are few who outright deny the existence of all deities. But there are some who claim that such beings are simply powerful spirits and not truly divine, and are not responsible for Creation. Apathy is a much more common attitude. Some people simply never think about religious matters, and don’t know or care to know the truth behind the beings worshipped as deities.
