The funky nose is courtesy of the last patches , but the "Mongol" holding pics ( actually horsemen cultures pics ) mean that Constantinople somehow was converted from the Greek culture to a horsemen one ( I would bet in a mongol invasion, but without more context ...).It gets worse. these are the Knights of Santiago. Their neighbours were the Knights of Calavatra. Two Spanish orders inhabiting Greece. Don't know how they managed to pick up the Mongol holding pictures or funky nose though!
