A thousand years of powerful magic still lingered within the abandoned castle of the two sisters. This magic had begun to slowly manifest itself, creating a powerful being that would become a living nightmare. This manifestation had chosen the form of an innocent filly. Some odd years later, the filly gains a will of its own, and became mischievous. She had caused the old castle to appear haunted, so as to prevent trespassers from further investigating the wreckage and taking anything that was of importance to her. One day, she had figured out a plan of her own. One that would terrify all of Equestria.
