I own Nothing of Harry Potter if I din it would have been H/HR.
Prologue:
An old man finished the Runes on the wall. 200 years he had worked towards this moment. He had studied magic of all kinds. He held Masteries in Potions, Transfiguration, Charms, Defense Against the Dark Arts, Warding, Runes, Arthimacy. He had worked as a curse breaker and treasure hunter finding the materials he would need. He had made discoveries that were once thought impossible. A potion that turned werewolves in Animagi allowing them to change at will but not pass on the diseases to those they bit was just one such discovery. A new way of travel that allowed instant travel with no adverse effects. He called in Sliding as that is what it felt like you were doing.
However, all his work led up to this one project. He would save her. She had died saving him in the third blood war. This one not waged by a terrorist group but by the government themselves. The so called light. After he had killed Voldemort things appeared to be going good. He was engaged to his best female friend and love of his life, Hermione Granger. Then the laws started to be passed by Percy Weasley the new Minister of Magic. Small at first but then larger and larger in scope. All against Muggleborns, blaming them for the war with Voldemort. Taxing them 40 percent on sales and 20 percent on income. The war had started soon after. Muggleborns and the few Half-bloods who sided with them versus the rest of the Wizarding world. It was in the Final Battle that she died. Killed by a man he had once called a friend a brother, Ronald Weasley. This happened while he was dueling a man who had once called a Comrade, a mentor, Auror Kingsley Shankelbolt. He had lost it. He jumped into the battle holding nothing back. When it was over he had went to the Ministry and killed every Pureblood who worked for them.
For the last 200 years he had prepared for tonight. It was the night when he would use a ritual to send him back to his childhood. He was aiming for when he was seven. This was for several reasons. The first was at seven you could claim your family titles, he had found that out after the war, and become emancipated and get his family Grimoirs. They had spells he would need. It also allowed him to gather his resources and prepare for the wars that would come. This time he would be ready for the first one. He would end it so hard that not one person would ever dare go against him. He had a plan. This ritual would send his mind, powers and abilities back into his seven year old self. The final reason was that was when she had told him she had started to exhibit accidental magic. Once he was emancipated he wanted to become her magical guardian. If he was he could protect her and anything he did bar the unforgivable to thosewho attacked her or insulted her would be legal. Not that he needed to. He now knew spells that could cause a lot more damage. Atlantian Battle magic was anything but nice. He just needed to break into that crypt again. It would be child play of course as he had memorized the ward schematics and where the traps were.
He would then go to Gringotts and claim all the families he had rights to. He would then start his plan under one of the obscure or more distant relative names. She would survive, she would be happy, they would be together. Let that "greater-fucking-good" old goat fucker or Those Weasels try to stop them. He walked to the center of the chamber and began the spell. As he was chanting he focused on the time he wanted to join. He brought his wand to his temple and uttered the spell that would end this body thus freeing his soul, his magic and his mind for their journey to the past.
"Avada Kedavra"

Those two words ended the man life but powered his ritual to its completion. With a ghostly smile on his face Harry Potter, the most powerful man since Merlin, left that plane of existence as it started to unravel. The ritual was a success.
