Headless Knight

A monster with no physical form that wanders the grounds of the Academy of Music. It despises the living and kills them by inflicting curses upon them with the power of darkness. This vengeful spirit did not receive a body of flesh upon its resurrection, and thus detests those who comfortably live the life it so desperately desires. Holding its head under its arm, it often takes the form of a headless knight on a horse, but it is ultimately transient, disappearing like mist over time.
