Tbh, I think he doesn't actually even have the required provinces in Persia, southern Georgia and the QK provinces at the Caspian Sea. But it is not up to me to judge
I think you're talking about my campaign.
I see that I do not have the proper provinces. I certianly can retry! I have 9 years left when I decided to just have some fun conquering a bunch of provinces of the timiruds, I didn't look that well at the eeastern borders to be honest.
ABTKING, too have things clear about the eastern borders, you mentioned Fars, Ajam and a "M" province (its called: Mazandaran), do you need to conquer eastwards up too these provinces?
Also I looked at the northern borders of the bonus region 2 in your challenge post. It runs straight through the province Imireti and makes it unclear what you need to conquer for that region. Do you mean the black line or white line?
