Thanatii

A classification of creatures that exist on Ur. A title designated by the great scholars of the land. Roughly translates to "children of death", each creature is classified by curse that created it. A curse is a spell that changes the fundamental nature of a creature.

They are further classified by how they sustain themselves from the Erosi. They are typically long lived or immortal. They often reproduce using the material remains of the Erosi or by converting living Erosi.
