Gullveig

Norse Mythology: A Vanir goddess. The Aesir's attempt to kill her brought about the first war in the world (the Vanir against the Aesir) which the Vanir won. The two tribes exchanged gods and then ruled together. Gullveig [Power of Gold] has been identified by some as the Triple Goddess, which was prevalent throughout the old world. Also called Heid [witch]. According to some she is Freya.
