In Norse mythology, Odin was a one-eyed god, the wisest of the Aesirs and their leader, displacing Thor. Odin was also a god of the dead. He helped to slay Ymir.
Odin was accompanied by two ravens who informed him of the doings of the gods, giants, dwarves, and men. He lost his eye in exchange for a drink from a sacred well full of knowledge and learned songs and runes by hanging onto Yggdrasil for nine days. At Ragnarok, Odin dies while fighting Fenrir. Odin is also known as Woden among the Teutons.
