The Delgeth is a flesh-eating monster from Navajo mythology. One of the anaye, or alien spirits, it resembles an antelope or elk. It is sometimes said to have no head, but a huge maw filled with razor-sharp teeth.
The legend says that the heroic Nayanezgani slew the beast with the assistance of some of the land’s native animals.
A very strange legend to be sure.
Improbable, to say the least, but keep in mind that outside of our arrogance we basically know diiddly squat about nearly everything… so… yeah.
