[Knai]

As far as I know, there are next to no nations based on the region (Arabian peninsula, northern Africa, al-Andalus, the remnants of the Sassanian Empire) at all. The few that are are extremely ancient, and based on Jewish myth (e.g. Ashdod), or are based on nations that conquered the region but aren't centered there (Ermor, Arcocephale). Actual Persians, let alone nations based on the Ummayad or Abbasid Caliphates. I might just be spacing something.
