@Bunsen @Eiregoat @Angel1313 @Dagnar @RichardKuklinskisIcyGlare @freddie_the_fed Zoroastrianism is an old Aryan religion (Not a Skyfather (What we'd call Pagan) one though), mainly in Persia IIRC, It's where Dualism comes from with Zoroaster and Angra-Mainyuu/Ahriman (that's Fate's version of him there), being the 2 dualistic gods, one of the funnier bits is there's a bit in there about Alexander burning their big goat hide Holy Book when he took the place over, so they deem him Alexander the Cursed lol. I'm not the most knowledgeable on it, and Neo-Platonism I don't know at all.
EDIT: So Wikipedia tells me it split off what essentially is the Vedic faith, If you don't know that's pre jeet-bastarization Hinduism.
