IIRC after the Muslim conquest of Persia, there were some Zoroastrian remains in the north that held out until the 9th century or so. Now, is it possible for this Zoroastrian kingdoms to not only survive but invade southwards Asturias-style?
I'm thinking primarily about the Anarchy of Samarra, which I think the Caliphate was at its weakest point; is in that precise moment possible? When did the northern kingdoms loose the opportunity to take back Persia?
