Wendigo

Ancient Amnian tales tell of a vicious, bloodthirsty creature, Stygian in nature, that are the incarnation of a deceased person's evil doings. They are rare, causing many to believe them to be but myths, but many of the old Amnian sages say otherwise. Legend has it that the wendigos live reclusive lives in the forest, and they only come out every hundred years on a full moon, where they go on a 3 day long spree of murder and bloodshed, turning those they don't turn to bloody ribbons into more wendigos.

Origin
Like many other Stygian creatures, the origin of the wendigo is unclear. Lost to history, some speculate that it was a product of an evil wizard's experiments, much like the owlbear, though this is unlikely. Several Amnian sages and priests agree that the wendigo was simply a curse set upon mortals by the Amnian gods, though we have yet to discover why.

Though whatever their purpose and origin, wendigos have played a large roll in Amnian culture and history. Such instances include the formation if the Vigil of Phola.

Physiology
Wendigos have a likeliness to be mistaken for undead, as they have rotted flesh and protruding bones like an ordinary zombie. Resembling hunched, anthropomorphic deer with ripped flesh and glowing red eyes that seem to stare into one's soul, wendigos are infamous for their abnormally long forearms and crooked teeth. Being just slightly taller than the average person, wendigo stand around 7 feet in height, and weigh an astonishing amount compared to their size. They are extremely fast and strong, capable of separating a humanoid's limbs without having to use any form of cutting tool.
