Tainted land

Tainted Lands or Diametric stains are regions characterized by their hard but invisible borders past which the nature of reality changes dramatically from the norms of the realm. Their sizes may vary substantially and the nature of some may be quite pleasant.

The term Diametric stian refers to a trend that some Schollar's thought they observed wherein Stains seemed to be opposite to the realm they were on.

Diametric stains are not natural. They have to be created. Most of them are scares from a long past conflict.
