Changing the past
This one thats place after the final battle, the light side has lost. Harry is locked in a cell under Malfoy manor. He has been locked in the cell for about a week with no food and water, everyday he was crucio'd by a different death eater. Everyone he knows is either dead or enslaved. Just as he thinks he is going to die in that cell, Lucius Malfoy and Fenrir Greyback drag him out of his cell. He is dragged to a sitting room and glares angrily at Voldemort sitting there. Just as he was about to speak, Bellatrix drags in a beaten Lyra Malfoy.
Harry knew that Lyra switched sides during the battle and it seemed she was punished for that. Looking at her apearance he saw that her clothes were torn and was covered in cuts and bruises. Her neck, which was always covered by an outfit with a turtle neck, was torn off and the word 'traitor' was carved into it.
Lucius gasped in shock at his daughter's apearence, but did not move from spot next to Harry.
Voldemort basically tells Harry that he will kill him soon, but first he will give his faithful servant a treat. Fenrir suddenly grabs Lyra with a feral sneer, and Harry knew what was going to happen. But before he could struggle against Malfoy, said Malfoy raised his wand at Greyback, demanding he release his daughter. All hell broke loose, Lucius Avada Kedava'd Bellatrix, Greyback slashed Lucius' throat, and Harry stabbed Greyback with Alecto Carrow's blade. Voldemort yelled and pulled his wand at Harry and sent the killing curse. At the last second Lyra put herself in front of the curse, but both her and Harry died.
Harry came into conscienceness when he felt someone shaking him. He cracked one eye open and saw Lyra Malfoy begging him to wake up, she looked a lot better than the last time he..
Harry immediatly stood up and noticed their environment was just complete whiteness. Suddenly a figure appeared, it was an elderly man in all black, he introduced himself as Death. He told the two young adults in front of him that it was to soon for them to die. He tells them he has a task to change the future by influencing the past. He tells them that if Tom Riddle had just been loved, things would have been different. Lyra ask how her and Harry are to do this, but she suddenly pauses and realizes what must happen. It seem so does Harry who flat out refuses and believes he can never love a child who will grow up to kill all his loved ones. Death tells them that even though he had no right to ask them of this, especially with the hand they had both been dealt with in life, Death believe through these experiences they would understand what Tom Riddle went through on his own. He goes on and tells them that no one had ever loved Riddle and he turned his loneliness and pain into hatred. Finally both Harry and Lyra agreed.
Death told them they will raise Riddle as their own. Death gives them new identities as Harry being Hadrian Peverell, only male heir to the line of Antioch Peverell. (Death wrote in a son to Antioch.) He also changed Lyra's name to Lyra Peverell nee Delacour. A young, married couple.
Death had told the new couple that he has taken care of the rest, he gives them a port key and tells them each to do an inheritance test. Before Death sends them away, he tells them he left them a letter each to read when they get their vaults. Suddenly Harry and Lyra appear in the Peverell Mansion on January 2, 1927, two days after Tom Riddle was born. Immediatly they head to Gringnotts. ( You can decide what happens here.)
When they were in their vaults they both found a letter each addressed to them from death that would help their situation
( Lyra: love him like your own, Harry: Don't become another Severus Snape or Vernon Dursley.) Afterwards they head to Wool's Orphanage. They meet the woman running the ophanage and they say they are looking for a baby. The woman shows them a re ent addition who is about two days old, Thomas. When Lyra first sees him she cannot imagine how a small infant could be a killer, her heart breaks and she swears she will be the mother he needs. Harry reluctantly promises something similar.
Lyra goes over to the infant and holds him, the baby doesn't even open his eyes yet he curls as close as he can to Lyra's heart, no doubt he feels her magic. They adopt Tom Riddle and start their adventure as parents. And with their love Thomas Peverell becomes an amazing wizards.
