Nicholas
All hail the jolly fat man. Santa Claus, also known as Father Christmas, Saint Nicholas, Saint Nick, Kris Kringle, or simply Santa, brings gifts on Christmas Eve of toys and candy to well-behaved children, and either coal or nothing to naughty children. He is said to accomplish this with the aid of Christmas elves, who make the toys in his workshop at the North Pole, and flying reindeer who pull his sleigh through the air. Santa is a mystical creature tied to Christmas/Yule itself. If Christmas is introduced in a new world and enough believe in it, he is able to shift into that dimension to deliver presents, which in turn gets him more believers, which keeps him alive and strong. When Havens guild master attempts to recreate Christmas in his new home world Santa gains access to it. He visits Haven to learn more about this new place, since its celebration is what allowed him access. He quickly amazes and befriends every one Havens members, even eventually Zelda the shoggoth. For reasons known only to her and seemingly him, she initially seemed incredibly fearful of Mr. Claus. As stated however, she now treats him as one of the most revered guests when he visits.
