The Arabs who live out of Arabia are called Mahjaris, and the Arabs who came to Mars, the Qahiran Mahjaris. When they arrived on Mars a good number of them began to wander Vastitas Borealis (”The Northern Badia") and the Great Escarpment. These wanderers were mostly Bedouin Arabs, and they traveled in caravans, in a deliberate recreation of a life that had disappeared on Earth. People who had lived in cities all their lives went to Mars and moved around in rovers and tents. The excuses for their ceaseless travel included the hunt for metals, areology, and trade, but it seemed clear that the important thing was the travel, the life itself.

In practical terms Al-Qahira was the pan-Arab dream come alive, as all the arab nations had contributed money and people to the Mahjaris. The mix of Arab nationalities on Mars was complete, but in the individual caravsn it seperated out a bit. Still, they mixed; and whether they came from the oil-rich nations or the oil-poor ones didn't seem to matter. Here among the foreigners they were all cousins. Syrians and Iraqis, Egyptians and Saudis, Gulf Staters and Palestinians, Lybians and Bedouins. All cousins here.
