NOTE 1: The idea of "in every culture" is a bit of a misnomer. They might be know, but they don't always mattee. Dunmer are a perfect example of this. They recognize the existence of the Aka and Lorkhan aspects, as we see them in the Sermons, but they aren't worshipped. Similarly, in Bosmer culture, Lorkhan exists but doesn't really matter. They don't believe he created Nirn.
NOTE 2: Hist, and by extention Argonian, should not be included in this as Hist are not native to Nirn.
NOTE 3: They are all of the same soul but are not the same being.
