Odin

While exploring the Halls of Lost Legends, enters a room marked "Asgard", there, he sees a petrified, seated Odin. Searching for answers, he holds up a shield marked with a turtle design, and sees Odin's reflection with tears running down his face. He then deduces to hold the shield up to the Halls' mysterious "curator" Locke, which reveals him to actually be the trickster god Loki.
