AN: This first chapter will be kinda short, but don't worry it will soon pick up. This chapter is just a way to be mysterious throughout the story. I hope you enjoy reading it and please review with your thoughts on what you think of it.

Prologue
During the beginning of the summer holidays, when all of the students and teachers left for their homes, they believed that no one, other than the school's ghosts, would be in Hogwarts. But they were wrong.
Every year during summer for the past one thousand years, a beautiful woman would walk the halls, she would be smiling and humming a tune to herself. Nobody knew that she existed, but Albus Dumbledore suspected that a greater power was protecting the school.
This woman kept The Dark Lord and his Death Eaters out, with her own special protection charms. She stopped people from Apparating in and out of the Hogwarts castle and it's grounds. Everyone who had ever entered the school and had heard of the enchantments surrounding it, believed that they had been put up by the school's founders, Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw and Salazar Slytherin.
Every year she would watch the students going about their business, unaware that they were being watched. But out of all the students over the years that she had kept her eyes on, three people in particular had caught her attention. Severus Snape, Hermione Granger and Harry Potter.
For the first time in a thousand years, she was planning to meddle in another's life. She felt that she no longer had a choice. She would make them see reason, and to show them that being nice to each other wasn't considered a sin.
Even being who she was, she did not believe that you were born evil. Only Tom Riddle had managed to defy that knowledge. It sickened her to know that she was related to someone so vile and evil. But she was good and pure, even though she is the first born daughter of Salazar Slytherin.
