well, I know that there are a few select religions, but I myself have not been apart of many :- the one that I know the most about is Lumenari group, a religious cult, for lack of a better word, that worships the sun.
ummm.....I know that there were, at one time, more religious groups but I'm not entirely farmiliar with them....Rhi would probably know a lot more about the subject matter than me!
