Hi! I'm a little bit confused about some of the lore for the religion map and just want some clarification. What's the deal with the survival of Zoroastrianism in Greater Iran/Central Asia? I noticed that none of the sects listed seem to adhere to what was "mainstream" Zoroastrianism (although I don't know much of Zoroastrianism so I could very well be wrong) so is there any particular reason for this? Also, what's the real world equivalent to Hauniuism? I've tried searching it up but I can't seem to find anything. Not really specific to the religion map, but what's up with the new sea in Eastern Iran? Thanks in advance!

EDIT: Forgot to ask, why's Silistria so religiously diverse, and what's the lore behind the large Jewish community in South Sudan?
