Yoma are beings that shapeshift from human to an infinitude of gargoyle like forms. Similar to humans, Yoma vary in shape, from skeletal to muscular with distorted humanoid bodies.

Yoma suffer from an almost constant hunger for the entrails of living humans, and often rip open their prey and begin feasting while their victim is still alive. Feeding on a human's guts grants the Yoma the memories and life of their victim. They love to use their shapshifting ability to assume the form of the last person they have consumed, and infiltrate their way into human settlements.

A few Yoma gain a mutation after feeding on at least a dozen humans to sprout wings and fly. These winged variants have a flying speed equal to twice their normal movement speed, and will often use their power of flight to either ambush isolated humans in the wilderness, or to escape if they feel a battle is not going their way.
