Nice! Just a few things to fix about the backstory: Berber society is semi-nomadic in nature, so there's no unified kingdom of Mauretania, and the "inheriting land" thing doesn't make too much sense, as there are no "lands", just clans and tribal chiefdoms. Also, Berbers are either pagans or Marbouti Muslims, as there are no other currents of Islam which are widespread among them. Some basic level magic is fine.
