The Kaskathan Desert, or Kaskathan High Desert, is a location in Vandal Hearts: Flames of Judgment.

A great stretch of rocky sand near the heart of Balastrade. Travel through the desert is known to be extremely dangerous, thanks not only to its heat and scarce water, but also to its fierce creatures. Those who must cross the desert take shelter in its ruins, and travel by night.
