Morrighan, in Irish mythology, was one of the three war goddessess who symbolized the death aspect of the Triple Goddess. She possess the ability to appear as one or three beings and could shape-shift into raven form.
Ravens are birds of omen - the distinctive harsh voice of a raven prophesied the future and the outcome of battles.
Morrighan fell in love with Cu Chulain, the son of Lug, and he rejected her. Legends state Morrighan continued to harass Cu Chulain on the battlefield in anger but it is also written she tried in vain to save his life.
Cu Chulain slept in the open wilderness after a long battle. He abruptly awoke to a high-pitched raven cry. He eyed a woman dressed in a rich, ruby cape and hood. Her fiery hair blew wild with the wind. Morrighan stood in a chariot drawn by a red colored steed, holding a long wooden spear in her grip. She portrayed herself as a lustful being and offered him a liason. Cu Chulain insulted her, choosing unkind words to refuse her request. In an overbearing tone, he told her he would rather nap than be bothered with the likes of her.
Morrighan possessed many magical skills she tried to share with him on how to win his next battle. He refused to give consideration to her heart felt advice. She became motivated by her anger. The friendship she had once offered was no more. Morrighan changed her form, swiftly shape-shifted into a raven, then flew away.
A short time passed when, still shaped as a raven, viewed Cu Chulain mortally wounded and bound to a standing stone. She witnessed his enemies behead him, and the passing from earth his spirit. ******
The two individuals could not communicate on an equal level of respect or allow the failure of the romantic expectation that brought disappointment be, so they could become stable friends.
