Hello

I'm playing Fallout 2 and trying to RP. I need to know, what sort of religious beliefs do Tribals in the Fallout universe adhere to? I'm guessing they differ, but most importantly what do the Tribals in Fallout 2 from which your pc (player character) comes believe in? I see references to Sky Spirits or something but no explanation on what they believe, if anything. Do they worship the Vault Dweller as a deity? If so, what does that worship entail?

Any explanation around?
