Voldemort

While the Death Eaters attacked Hogwarts Harry abandoned all his friends it was then that he found himself in front of Voldemort

who said to him "where do you think you're going Girl? Don't you care about your companions?" Then Harry thought "I don't care about any of them completes me"

But Voldemort noticed the darkness in Harry's heart and said "why don't you join me I can make you whole let the darkness you have take over". Harry understood that by submitting to the dark wizard he could remain with his magic and told him "I don't remember anything but only that submission is pleasure and that only the man who gives me a name will be able to possess me and submit me". Voldemort thought "this girl is my horcrux "as soon as he saw the eyes he understood that the girl in front of him was Harry Potter and said "well I will give you a name so you will become mine forever."
