Hello,
Just started making my third map and this is the first look of the development.
I did some research on the coat of arms and the position of the mega bonuses. The most likely possibilities are Latin Empire, Byzantian Empire, Kingdom of Jerusalem, Sultanate of Rum, Armenian Kingdom of Cilicia, Abbasid Caliphate, and the Fatimid Caliphate. There is also some space for incorporating the military orders of the Teutonic Knights, Knights Hospitaller, Templar Knight and the Hassasins.
Your comments and views are as always very welcome :)
