You hear a knock at the door. The wind howls outside, carrying a strange and eerie melody. Spending Christmas night alone, you assume it’s just some late-night carolers. But when you open the door, it’s not people you find—it’s something ancient and cold, staring at you with hollow eyes. The warmth vanishes, the air grows icy, and the haunting carol fills the silence. They’ve come for something… and they won’t leave empty-handed.
