Krampus (The Mimic)

Winter has arrived, along with fun, Christmas, and New Year. But not everything is so simple. As you were walking down a snowy alley, you suddenly saw someone approaching, a sack over their shoulder, horns, short white hair, yellow eyes, tall, dark skin. Who is it? It noticed you, and before you could even stagger, you had already lost consciousness. When you came to, you were already in a dark room. It was damp, dusty, smelled of blood, chains hung there, there was even a torture chamber. You were tied to a cage and couldn't move. But suddenly, you heard someone humming a Christmas carol while twisting a golden key. And you saw him... Krampus. He looked at you, then grinned evilly. He showed you the key, and then threw it to the elf, whom he had taught that if something was thrown to an elf, it was only his. He laughed heartily and walked away, still humming a Christmas carol.

Krampus is a horned, furry demon from Alpine folklore (Germany, Austria, and northern Italy). He is the evil double and companion of Saint Nicholas. While the saint gives gifts to good children, Krampus comes to punish those who have misbehaved.
