Congrats for the release !
I went to see some intriguiing starts in the Iranian world... Which brings some comments / questions (or more "wishlist items" you may just disregard

)
Is the fact that the city Siraf (province Irahistan) is the province capital but the holder is feudal? Should not this be a "Republic"? I know, we don't have much information about the governance of Siraf, just that it was an important trading city connected to the Indian subcontinent so I understand that you may have decided so
A Siraf Republic game with Zoroastrian and Indian "Patricians" would be so neat, even if getting dangerously close to fantasy...
The other question relates to an Afshin start in Ohrusana. Nice set up!

But a small comment or question. When looking at a possible Soghdian revival game, I immediately became Tajik. Well, again, in 867 I recognize that the Soghdian culture is disappearing... But still, I wish a player could decide to retain it. After all, the Yagnubi language spoken in the Zarafshan valley today just next to the in-game province of Ohrusana is considered a "survival" of the Sogdian language.
Then, let me continue on my Afshin dream and make a suggestion. What about including
these guys (the Sajid) related to the Ohrusana Afshin? Encoding them as (still) Afshin dynasty, but probably not Soghdian anymore could generate nice alliance possibilities
--- Edit: sorry I found the Sajid, encoded as Al-abi'l-Saj but still Soghdian and a claim on the Ohrusana region

nice start idea
