Wendols

From Multiversal Omnipedia

The Wendols were primitive, sub-human warriors who were rather neanderthal-esque in appearance and nature. They fed on their dead victims, and acted in a way that convinced their foes that they were supernatural monsters. The Wendols attacked a Viking settlement in the year 992, but, with the help of 13 specially selected warriors, their leader was slain and the Wendols defeated.
