Wendigo walks in the woods and sometimes unholy grounds. Nobody knows what they look like up close because people go mad if they cross one. Afar they are bigger and taller than a grown man, they are covered in hair, and wear ragged clothes or none at all, and walk on two feet. No good can arise of them, if you cross their tracks you will wander forever. Any ground they touch is defiled, and will remain so for a very long time. They can catch you in dreams (If you dream of one you will become one,) you will dream of eating human flesh, and develop a taste of human flesh even when food is in plentitude. During your infrequent lucid moments you will beg for death. Sometimes they will lead a child off to an unquiet death (E.G. Oliver Larch), and the footprints of one who has become Wendigo will be bloody, and they will suffer from the heat.

This is from a close friend (I think soon to be fiancee`) of my cousin's, who is three-quarters Native North American, she grew up in the Canadian Rockies- I have no clue where her familyy was from before then, though.

FWIW
