Unreal Desert

From Mondarth Codex

A tract of the Prukath desert belt that was warped during the Magic Wars leaving the landscape scarred by regions where the barriers between Spheres of Existence are weakened. These regions are in constant flux, unwary travellers can find themselves (or worse, part of themselves) carried to another sphere of existence only for the region to shift and the bond between spheres be broken. Best case, you end up transported to the other sphere, worst case only part of you is transported and things can then get messy.
