Also known as an "ondine", this is beautiful, ghostly female spirit which haunts stretches of water in many European countries. The spirit type is believed to be comprised of young women who have died by drowning, usually having committed suicide as the result of a broken love affair. Although the undine is regarded as a tragic figure, traditions hold that this spirit means no harm to the living, although heartless or unfaithful lovers may become haunted and tormented by these ghosts.
