A male Austrian faerie called Krampus is said to be very ill-tempered. He is a bit like an elf of Christmastime, but unlike the "Santa's elves" type who love children, this one specifically exists to punish children who have been bad, or just ones that he sees fit to punish. Offering it kindness will simply make it leave without harming you; trying to fight it will only bring on misfortune.
