The Will of Valar
Disclaimer: I don't own Harry Potter or the Lord of Rings
Prologue
Lilith Alexandria Potter was one when her biological parents were murdered by Lord Voldemort. She was the only one who survived that terrible night. She was taken from the house by Rubeus Hagrid the Keeper of Keys and Grounds at Hogwarts to her non-magical relatives' house in Surrey. They were met at the Dursleys' by Albus Dumbledore and Minerva McGonagall. Dumbledore wanted to keep her away from the wizarding world to keep her from becoming arrogant and because of the blood wards she would been safer near her aunt at least that's what he had told them but this was not completely true, sure he wanted her safe but he wanted her to be meek and easy to mold into the perfect weapon, perfect but disposable, against Voldemort, who he was certain was not gone just without a body.
But Valar, the essence of magic, had other plans for her. Valar knew that she would be abused by those people so she transported Lilith to place she knew Lilith would be well taken care of. Valar needed Lilith to bring two people to their knees or kill them. They were Lord Voldemort and Albus Dumbledore. They both were upsetting the balance and they needed to be brought down. So Valar transported Lilith to the forest of Lothlórien to the house of Galadriel and Celeborn to be exact. That was ten years ago. This is where our story begins.
