The spirit is the protector and punisher of the Wendigo.(with a connection)

The Guardian Spirit of the Wendigo.

When the native tribe is pursued by enemies and the family is in mortal danger, the best warrior of the Indian tribe voluntarily agrees to a terrible sacrifice: he gives his soul to the spirits of the forest and becomes a wendigo. Turning into this creature, he helps the tribe to win, but then, when the threat is eliminated, the warrior can not become a human again. His sacrifice is accepted – and he goes forever to the forest, where he finally turns into a wendigo.
These wendigos are different and some even do not mind eating you, but this is a good wendigo, if you can say so about it at all.) He will protect you to the last drop of Vendhya blood, rest assured.)
When he finds an enemy, he can sneak along the trail for hours. Usually, sooner or later, a person begins to suspect something, begins to listen, look around, but it is not so easy to notice the wendigo. Then he begins to frighten his victim: sometimes the enemy hears strange sounds, it seems to him that someone's silhouette flashes, he begins to suspect that there is someone else here besides him, and this "someone" is moving so fast that the human eye can not notice it. Sometimes the victim hears a whistle that resembles the rustle of the wind. At the level of ultrasound, it chills to the bone.
All this makes even a man with strong nerves panic and run, and that's when the wendigo gives chase.
Without need, the wendigo does not attack and sits quietly in the forest, but woe now to the one who offends you.
The work is very serious, the wendigo is really scary, believe me.)
