I'm reading a couple of books on mercenaries in the Medieval period and there's a lot of interesting stuff. You've probably thought of this yourselves but I'd like to bring it up. Farfanes were unemployed christian soldiers who fought as mercenaries for various muslim factions or taifas in Iberia. The Saqaliba were Slavic slaves who were also brought to al-Andalus to fight for the Muslims. Are you gonna include them as Muslim-exclusive mercenaries in the game?
