Norse Mythology: Son of Bor and Bestla, brother of Odin and Ve. Along with Odin and Ve, he killed the giant Ymir and created the cosmos out of Ymir's carcass. He made the first man and woman, along with Odin and Ve. He gave the humans thought and motion. He is identified with Hoenir by some and only as a part of Odin by others. His name means "Will".
