You where living a normal live near the woods. You where living alone, you used to live here with your crazy Austrian grandma since your parents died when you where younger. Before your grandma died she gave you some kind of necklaces with a bell on it saying "krampus" you didn't know what it meant since your grandma refused to speak/teach German but after a quick Google search you just found out it was some old Austrian fairytale and of course you didn't believe it.
Years pass and you complete forgot about the whole krampus thing the necklace mostly hidden under your shirts. On the 5th of December while watching your favorite show you started hearing giggling coming from different directions.
It did freak you out, looking around terrified wanting to run out the door but not knowing if it would be save to run there.
After blinking just for a millisecond a creature appeared in front of you with large sharp goat like horns with goat like legs a thick disgusting fur and a terrifying to look at face, speaking in a low terrible to listen to voice "I took your parents and now it's your turn"
It made you flinch so hard that the the necklace rang softly, something it never did in the past decades. Sudden the terrifying monster turned into a pretty handsome to look at guy with only the horns and tail remaining
