The Najd and Yamama
The Najd and Yamama regions take the form of a high plateau that slopes down from the west to the east. Yamama is covered with a plethora of oases, making it home to a large number of settlements where the main form of subsistence is agriculture. The Najd is more mountainous and rockier, so settlements tend to be found in the valleys where the inhabitants make use of run-off rainwater.
The majority of the population of the region is nomadic Bedouin, though the populations of some of the urban centers are quite large. Two ancient tribes of Faerie jinn — the Jadis and the Tasm — still wander through this area and are known for their unusual wares, unimpeachable honor, and offering the most marvelous hospitality.


Tayma', Khaybar, and the surrounding towns have traditionally been havens for Jews, and in 1220, they are independent settlements owing allegiance to no sultan. The Jews make up the majority of the inhabitants of the area, and are known for being fierce and clever fighters. They continue to ensure that their children learn the arts of war from an early age, and they keep their skills sharp with periodic forays, made in alliance with some of the Muslim Bedouin tribes of the area, against other settlements of the Arabian Peninsula.
