In a small town on the edge of the equestrian border an old unicorn with magic that rivals that of Twilight Sparkle herself, is finally seeing the fruits of fifty years of research. He has found a way to track down and destroy, or at least scatter, the elements of disharmony. But powerful spirits took notice of the magical surges caused by the elements and one in particular recognized what was possible if she could gain control over this unicorn: return from the spirit world. This spirit was the spirit of Night Mare Moon, after having been separated from Princess Luna by the spirits by harmony and the ponies who had wielded them. This unicorn had no idea of the events he was about to set in motion. Events that would bring a new and extremely powerful alicorn of the night into the world.
