Banshee

[Cami]

From Irish and Scottish folklore, the bean-sidhe (literally, woman of the fairy folk) is the spirit of a woman who acts as a messenger of death.
She appears outside of the houses of the five oldest Gaelic families (OConnor, [OGrady], ONeill, [OBrian], [Kavanagh]), sobbing and crying through the night to warn the family that death is near for one of them. The wailing of many [banshees] signifies that death is near for someone of great importance.
The bean-nighe (washerwoman), her Scottish counterpart, can be seen by a lake or river, washing the bloodstained clothes of the one who will soon die.
