Mohrgs are the animated corpses of mass murderers or similar villains who die without atoning for their crimes. Tortured by all-consuming hatred of living things, they long to live again.

A mohrg looks like a gaunt, nearly skeletal corpse and is easily mistaken for a zombie or ghoul. The creature's tongue is its most noteworthy feature - long, cartilaginous and clawed.
