Wendigo
In Algonquian folklore, the wendigo () or windigo is a mythical man-eating monster or evil spirit native to the northern forests of the Atlantic Coast and Great Lakes Region of the United States and Canada. The wendigo may appear as a monster with some characteristics of a human or as a spirit who has possessed a human being and made them become monstrous. It is historically associated with murder, insatiable greed, and the cultural taboos against such behaviours.
Jack Fiddler
Like his father before him, Jack Fiddler became a famous shaman for his alleged ability to conjure animals and protect his people from spells. Most importantly to the people of the region, he could allegedly successfully defeat the wendigo, a cannibalistic spirit that would possess people during all-too-frequent bouts of famine and disease. In his life, Jack Fiddler claimed to have defeated fourteen wendigos. Apparently some were sent against his people by enemy shamans, and others were members of his own band who were taken with an insatiable, incurable desire to eat human flesh. In the latter case, Fiddler was usually asked by family members to kill a very sick loved one before they turned wendigo. In some cases, the "Wendigo" him or herself would ask to be euthanized according to the necessary rites. Fiddler's own brother, Peter Flett, was killed after turning wendigo when the food ran out on a trading expedition.
