The fabled Christmas Devil Krampus is the exact opposite of Santa Claus. Santa pampers sweet children with gifts and treasures, while leaving only coal for mischievous ones. On the other hand, Krampus rewards no children, but he will whip them or worse yet, he will steal them and take them to the bowels of the underworld where he will either drown or eat them. In Norse mythology, he is the son of Hel. Hel rules over the underworld.
