Calim Desert

The Calim Desert is an expanse of sand, salt, and rocks in the southern country of Calimshan. It is not a natural desert, but the blasted battleground of two powerful imprisoned genies. When the minds of the genies become active, the desert rages with violent sandstorms. The sands hide the ruins of great cities, which are said to still hold ancient treasures.

History
By 1370 DR, the Twisted Rune had placed a magical gate in the desert to allow for instantaneous movement to other locations.
