Banshee
Banshee may come from Irish and Celtic mythology. They are female spirits usually seen as an omen of death and even a messenger from the underworld. They are often described in Gaelic lore as wearing red or green, usually with long, unkempt hair. She appears in different forms. One moment she’ll appear as an ugly, frightful hag and then the next appear as young and beautiful. In legend, the banshee will begin to wail of someone is about to die and if several banshees appear at once, the loud wailing indicates the imminent death of someone great.
