|Part of||New Argive|
|Formerly part of||Great Desert|
It received its name because it lay west of west from Argive and Korlis. It was divided from the Great Desert in the interior of Terisiare by the Kher Ridges. This was once the center of the forgotten Thran Empire and would become part of the Western desert. During the Brothers' War, giant rocs were found throughout the region, preying on the adventurers searching for Thran relics.
