Also known as Morrighan, Morrigu, or Morgan, she was a Celtic goddess of strife, battle and fertility. Because she could appear as a single goddess or as a trio of goddesses (the members of the trio vary in different myths), she is called The Morrigan. She can take the form of a crow flying above warriors, although she has also been described as taking the form of a wolf, cow, or eel. Although the reference to the cow implies she is a goddess of fertility, she is more often described in ways that make her comparable to the German Valkyries.
