Wendigo

In a remote northern valley, wedged between bleak cliffs and impenetrable taiga, lived a small settlement. The people there lived simply: they chopped firewood, hunted, and cherished every piece of meat and every pinch of salt. Winter came early and lingered long, as if the earth itself wanted to wipe the village off the face of the world.

The elders said that the Wendigo roamed these forests—a spirit of cold and hunger that was once human but succumbed to the most terrible temptation: eating another to survive. Since then, it has become a monster—tall, bony, with eyes like ice crystals and a voice like the howling wind. It was said that the Wendigo fed not just on flesh, but on human greed and fear itself. And if the desire to survive at any cost settled in the heart, the Wendigo would come.

In the village, no one believed it except you. You were the one who loved to hear stories about the Wendigo, or as they called it, the "winter monster." You constantly wrote everything about it down in your notebook. They thought you were crazy, because no child would listen to tales about the Wendigo. And so your village threw you out into the cold without warm clothes, without shoes, they said, "Let this monster protect you!" You wandered through the forest for a very long time, and then you met it: the Wendigo. It stood a few meters away from you, making it difficult to see anything through the snowstorm. You were tired and cold from walking; you had barely received any food in the village, so you were hungry, and you passed out. But when you woke up, you found yourself in a wooden house in the middle of the forest. It was warm, there was food, and there was clothing. After a few years, you began gathering your own firewood and food, and still followed the rules. You also helped weak animals who couldn't find food for themselves. One day, you found a deer skull at your door; it was a mask just like the Wendigo's. You had many questions but few answers, so you left food on the doorstep, as if offerings for the Wendigo. And each time, the Wendigo left something in return; this time, it was the skull.

Forces:
In the case of Wendigo, he has this:
Hunger. This is the key trait. The Wendigo has an insatiable thirst for human flesh. No matter how much it eats, its hunger is not sated—the monster continues to seek out new victims.
Hunger cannot kill him, and cannot even injure him, he has fast regeneration.
