Imfene
The Imfene are monstrous creatures from the myths of South Africa. They are described as a unique breed of large, vicious, and powerful baboons. They are unnaturally smart and vicious and are known to kill humans both for food and for sport. Some believe they are witches taking the form of apes, while other stories suggest witches ride on top of Imfene as mounts. They can be killed by normal weapons but have been known to set traps in case humans attempt to hunt them.
