Banshee

Banshee, also called beann'shie, is a female spirit who cries on Saovine night, wailing a warning of those who will die.

Banshee is not a malicious spirit, though meeting one is considered to be an omen of the worst kind.

Their appearance varies, though most often they're pale, thin women vested in grey raiments, with burning red eyes.

Trivia
