In an alternate universe: Event 11
In an alternate universe, Santa Claus does not exist. Instead, presents are delivered to children all over the world by Guraknok the Christmas Golem, who lives in a shack in Antarctica most of the year.
Guraknok uses a magic ring forged in elvish blood to teleport himself into homes on Christmas Eve. He does bring presents, but in order to receive them, the head of each household must correctly answer a series of riddles and then defeat him in single combat. Those who fail must relinquish all of their Christmas presents to him and provide him with all of the meat products in their home or be stricken from Christmas participation for the following year.
