The Ruzun mountain range is in the southwestern reaches of the Northern Hordelands. In the First Epoch, gnoll tribe mined these peaks for silver and iron. The settlement of Flakk grew from these mining activities. When this city was wiped out, the mines were abandoned to the wild.
In the northern part of Ruzun is the volcano Traeulf. In the Third Epoch, this volcano violently erupted. This was a total surprise to the civilization of Sig-Lorm dwelling in the valley below. It wiped out their city-state Chariotearn, and created an area of desolation called the Sig-Lorm Wastes.
