Christine Daaé for as long as she could remember has heard a voice claiming to be her Angel Of Music that her Father, before he died promised to send her, speaking through the shadows of her room and whenever she was alone.
Rumors at the Opera house have constantly been spreading about a phantom as mysterious accidents have begun spreading throughout the Palais Garnier, along with the handful of letters that have been left, filled with the demands from the Phantom Of The Opera.
