The Irish Morrigan, Goddess of Death and Guardian of the Dead.
Appearing before great battles as the goddess of war, death, and fate, the Morrígan offered prophecy and favor to heroes and gods alike. She was often depicted circling the battlefield in the form of a raven to carry away and eat carrion, though she could also appear as a beautiful woman to seduce powerful men. She was a cunning shapeshifter and a terrifying omen of death to the characters of Irish mythology.
