Odin, the Norse god of wisdom. war and magic, is called Allfather for he is indeed Father of the Gods and he played a central role in myths about the creation and destruction of the world. In the beginning, he killed the primal frost giant Ymir and from his bones formed our universe. He arranged the heavens for the gods, the middle world for humans and dwarfs, and the underworld for the dead. Finally he created the first man and woman from an ash tree and an elm tree.
