Priesthood in whatever form and religion is prohibited in Quran. Priests, Capitalists, Kings they are warned, for they hold influence over common people and don't let them exercise their free thinking and will.
I didn't get your question I guess, are you looking for a mention of anything related to Zoroastrian in Quran?
Yes. Obviously.
It's as if the Quran came up in an Abrahamic vacuum.
Highly suspect no?
