The Assyrians are semi nomadic people that live along the south eastern coast in the Great Desert. They have also settled the islands off the south eastern coast. Establishing port cities that are major trading posts.
The Assyrians are great horsemen riding the desert wastes looking for water or oasis. What semi permanent settlements they have in the desert are all located around major oases. Unlike the Nubians and Akkadians they have no warrior culture or standing army. Since falling to Pellans they have been under constant occupation. And unlike Adena, Nubian and Akkadian, who were aloud to oversee themselves, the regional governor has always been a Pellan.
The Pellan Legions have permanent outposts and strongholds all along the Assyrian land.
DM note the Assyrians are loosely based on Arabs(no particular nationality)
