The People of Ourgadun are the oldest known inhabitants of the area. Divided into five large tribes, their territory extends from the south-east of the Ourgadun river to the Cite de Sables province of Matidja-Al Chalef. The People of Ourgadun do not trade or associate with the rest of Mundus, except near the Darganof peninsula where some trade posts exist. There was a time when the Dourdun tribe occupied a vast territory north of the river, but they gradually abandoned it in the face of deeper and deeper incursions by the tribes of Felfel, Aswad and Sokkar. These last tribes are at the origin of the province Kazarun. During the following history, some attempts were made by the founding tribes of Kazarun to push their incursion south beyond the river, but they were met with fierce resistance from the people of Ourgadun and the attempts ended in failure.
