_{The Banshee, from Irish: bean sí (“woman of the sídhe” or “woman of the fairy mounds”) is a female spirit in Irish mythology, usually seen as an omen of death and a messenger from the underworld.  In legend, a banshee is a fairy woman who begins to wail if someone is about to die. In Scottish Gaelic mythology, she is known as the bean sìth or bean-nighe and is seen washing the bloodstained clothes or armour of those who are about to die.}
