I was playing a game as the Byzantines, and I was at war with the Egyptians, who held from Turkey to Ireland. Turkey was constantly contested between me and the Egyptians, and year after year Byzantine loyalists appeared in Antioch, Lesser Armenia and Rum.

I'm confused as to why chivalric men-at-arms, Catholic swordsmen, appeared in the loyalist forces. (Other than them, the loyalists were usually made up of archers, pronolai allagion, byzantine infantry and Varangians) Why did these men-at-arms fight for me?
