The days seem to drag by. Severus always seemed to find something to give Harry detention about. Everyone knew that Severus was his uncle. They just thought he didn't like Harry. They didn't know that Severus and Harry spent the whole time talking about his past or playing chess.

One night Harry was laying in bed when his scar starts to hurt. He jumps from the bed and apparates to Severus' room. He wakes him up and tells him that he thinks Voldemort is on the way. Harry than apparates to Dumbledore's office and wakes the headmaster up. Dumbledore picks up the intercom mic.

"All students and teachers are to report to the dining hall immediately." He and Harry run to the dining hall and wait. Dumbledore waits for everyone to get there. Just as he was getting ready to speak there was a loud explosion. The students start to panic. Voldemort has sent his Death Eaters into the school. They come into the dining hall.

"We have a message from Voldemort. If the everyone in the building doesn't come outside right now, we have permission to start killing people." Dumbledore looks at the teachers and nods his head. Everyone walks out onto the front lawn. Harry is talking to his companions as they walk outside.

'I need you five to stay with the students and teachers. I'm going to end this today. If I don't make it I want you each to stay with the head of your house. Hedwig stay with Hermione. I love you my friends.'

Voldemort starts to laugh. "Come out Harry Potter. If you don't I'll start killing." Voldemort points his wand at a group of Slytherins and says "Crucio" they all fall down and start screaming. Harry walks forward. He raises his hands and a shield goes around the student and teachers.

Dumbledore, Severus, Ron and Hermione run to the edge of the shield and scream, "No Harry don't."

Harry turns to look at them. "I have to if I don't end this now, it will never end."

Voldemort starts to laugh. "You end this now. This is going to be the day of your death."

Harry just glares at Voldemort. "Go ahead and laugh now Tom Riddle. How is everyone going to react when they find out that there is another Heir of Slytherin." Everyone but Minerva, Severus, Albus, Voldemort, and Harry gasp.

One of the Death Eaters steps forward, "What does he mean master? Another Heir of Slytherin?"

Harry laughs,"you mean he didn't tell you. His mother had a twin sister. She was my grandmother. Did he not tell you that one of the heirs is half muggle. That's right. My mother was a full witch. Her and Professor Snape share the same father. So that means that Voldemort is half muggle. Tell them why you killed my parents. Tell them."

"I didn't want anyone to find out my father was a muggle. You should have died when your parents did." Voldemort raised his wand and shouted " Avada Kedavra" pointing his wand at Harry. Harry just raised his hand and blocked the curse.

"How? How can you block the curse. Your mother was weak. Your father was weak. You should be dead." screamed Voldemort.

"Is that what you think? Well let me tell you something. I'm the strongest wizard to ever live. I just don't gloat about it. I am Merlin, or would you rather call me, Godric Gryffindor, Helga Hufflepuff, and Rowena Ravenclaw? I am the reincarnation of them."

"No you lie. You will die today." Voldemort changes his wand into a sword and charges at Harry. Harry closes his eyes and holds out his hand. Suddenly there is a bright light and in Harry's hand appears a sword, but not just any sword, it's Excalibur. The swords clash.

Harry's arm is slashed. He stumbles from the blow. Voldemort starts to plunge the sword towards Harry. Harry starts to glow. A bright white light explodes from him as he plunges his own sword into Voldemort's stomach. Voldemort screams and his body disintegrates. The glow disappears. Harry is floating in the sky Voldemort's sword sticking out of his stomach. Harry falls to the ground unconscious. The shield goes down as the Death Eaters are running away. Severus runs to Harry and picks him up.

Harry awakes sometime later in the hospital wing. He turns his head to see Hermione laying on his right with her head resting on her arms, asleep. On his left, Severus is exactly the same. He reaches out and touches each of their arms. They stir and awaken.

Hermione runs to get Madame Pomfrey, while Severus hugs Harry. "How long have I been out. Did I kill Voldemort?"

"You've been out for a week. Yes, you defeated Voldemort. You were stabbed in the stomach and you drained to much of your energy destroying his body, after you put up the shield. "

Madame Pomfrey came running in with Hermione on her heels. "Severus you and Miss Granger, go to bed now. He should be able to leave in time for breakfast." Poppy examined Harry then gave him a sleeping potion.

He awoke the next morning with just enough time to make it before breakfast was over. He ran to the dining hall. He opened the doors and the room went quiet. Suddenly everyone stood up and started clapping, even the Slytherins. Harry just looked confused.

'Severus explained to them that what was said was true. That you are the heir of Slytherin, but also the founders of the other three houses.' Salazar told him.

Dumbledore motioned for him to come to the front of the room. He clapped Harry on the back.

"Harry is to be commend for defeating Voldemort. As many of you noticed he didn't use his wand to do magic, that's because he doesn't have to. After he first woke up, we gave him his OWLS, NEWTS, and all the tests he would need if he was to graduate college. He passed each one with perfect score. Actually he taught us, the teachers and test givers a few things. He can do things ever we can't do. He risked his life to save the wizarding and muggle worlds. He has already graduated from Hogwarts and college. He just stays here to stay with is friends. From this day forward, there will be no tolerance for rivalry between the houses. No house is any better than the other, because of Harry. He is the Heir of Slytherin. He is also the reincarnation of Merlin, Godric Gryffindor, Helga Hufflepuff, and Rowena Ravenclaw."

"Why do you think those animals are with him? They are the companions to the heirs of the houses. Harry take your seat. There will be no exams for the next month."

Everyone cheers and digs into their food.
