-A Jump Back In Time-
At midnight on October 31, 1981, an adult Harry and Hermione Potter appeared in a little cave outside of Hogsmeade, a runic bracelet on their right wrists. They shared a relieved smile and a kiss before Hermione made a quick list:
-Diadem
-Locket
-Ring
-Diary
-Cup
-Riddle Senior's Body
-Voldemort
-Snape Memories
-Death Eater List
"Let's go then," Harry said. "We have lots to do and 23 hours and 57 minutes to do it in before our souls are wiped out."
Hermione took his hand and they Apparated to Little Hangleton. After sneaking into the graveyard they easily dug up the bones of Tom Riddle and Hermione sighed, "I'm sorry about this sir. I hope you're resting in peace." Harry bowed his head out of respect for a man who really didn't deserve what they had to do to his bones. He actually felt much sorrow for Tom Riddle Senior. A man who had been essentially raped under a love potion and then eventually murdered by the offspring of that rape; Tom had been an innocent bystander in all of this. Taking a deep breath Harry cast fiendfyre, destroying the bones completely. Fiendfyre always left no trace beyond a magical signature, much to their relief. Magical signatures couldn't be tracked to a specific person by the Ministry of Magic. A fun fact brought to light by one Dobby the house elf shortly before Harry's second year at Hogwarts.
Harry then led his wife to the Gaunt shack. Hermione's ability to break wards never ceased to amaze him. That trait would be very useful when they hit Gringotts. Once Hermione broke the wards down Harry used Parseltongue to unveil the ring. Using a dragonhide glove he picked it up and Hermione cast fiendfyre on it. Harry soon had to drop the ring from the heat but the green mist that exited and screeched as the ring melted and stone cracked signified they were done. Hermione stayed focused and stopped the fire. Harry cast aguamenti on the stone before picking it up, "We'll have to stop by the Ministry and toss this through the Veil."
"We will," she promised. The Elder wand would be nice too but they weren't going to be able to manage that. Keeping even just one of the Hallows from Dumbledore was enough. She took his hand. "We'll do that when we leave the head of the DMLE Snape's memories and the list of Death Eaters." He smiled before they Apparated. It was now 2:09 a.m. and they were two down, seven to go.
Next up was the locket. Harry wandlessly opened a window in Number 12 Grimmauld Place and Hermione summoned the locket from inside. The necklace came flying out and Harry deftly caught it before wrapping his arms around his wife and vanishing again, going to Gringotts this time. This one would take a very long time.
Harry cast the glamour charms over the two of them before they entered. Given the late hour Gringotts was mostly deserted. Harry followed up the glamours with two powerful disillusionment charms. They slunk to the carts and headed down past a dragon that Harry skillfully hit with a stunner as they flew past it, knocking the dragon out.
Entering Bellatrix's vault took about as long as they had expected. It was 4 am before Hermione had finished and Harry entered, destroying the locket and cup with fiendfyre. He easily removed the scorch marks from the floor of the vault before they left, resealing the vault. They exited Gringotts twenty minutes later and shared a high five before they headed to the Ministry. While splitting up would give them more time they needed to be sure they were safe. First stop was the Department of Mysteries. "They don't have security guards," Harry said.
"I thought at first Voldemort took out those that watched out but I think you're right, they just don't have security guards. So stupid."
Harry chuckled at his wife's attitude. He certainly shared that opinion. It was easy to see how Voldemort came to power. There was nothing to stop him from doing so. Harry tossed the stone into the Veil and they both sighed in relief. One less obstacle. They next headed up to the head of the DMLE's office. "Barty Crouch. He really hates Death Eaters."
"And his son is one," Hermione shook her head, "come on let's place the jars of memories in his office."
They placed Snape's memories in the office and then the list of Death Eaters. Just in case they couldn't recognize all the faces in the pensieve. The couple glanced at the clock. 5:48 am. "Malfoy Manor now?"
"Definitely," she gave a feral grin and Harry shuddered. One time, shortly before their seventh year, the Daily Prophet had called Hermione a 'Warrior Witch'. That reference had led Harry to envision her in the Xena: Warrior Princess outfit and it made his blood burn with desire. Harry shook his head to remove the image before following his wife out of the Ministry and again silently Apparating them away.
Malfoy Manor was difficult to break into but far easier than Gringotts. No one would ever know that anyone had broken into either location. Harry slipped in easily, Hermione watching his back, and found the diary. "We could light the whole house on fire," he suggested.
Hermione fought a smile as she tried to be the rational one. It was an appealing thought but they wanted no one to know they were going Horcrux hunting. Harry's puppy dog eyes were not helping. "Harry we shouldn't."
"You know you want to."
Hermione sighed, "How about we set up some hexes in the manor instead? Trick them into freeing their elves?"
Harry debated it for a minute before nodding begrudgingly. And so the couple went through the manor, casting compulsion charms on places to compel the Malfoys to release their elves as well as hexes and jinxes that would be difficult to almost impossible to remove. As they left Harry looked at the diary. Just the diadem and Voldemort left. Then they'd be free.
Hogwarts was easily entered thanks to the Honeydukes secret entrance. With no one in the school presently awake they made it up to the Room of Requirement easily. Forty minutes later the couple was chucking a diadem and diary into a kiln the room had provided. Hermione cast fiendfyre this time, the kiln destroying the two soul fragments. "I wish we could get the Elder wand."
"It's not feasible Harry." Hermione kissed him, "Your mum is brilliant. I bet she'll think of something." Harry glanced at his watch, 7:57 a.m. He looked at Hermione, who rolled her eyes, "The Warrior Princess fantasy?"
"I really, really like that one," he pouted, giving her his best puppy dog eyes.
She rolled her eyes, annoyed that that look still worked, before waving her hand to transfigure her clothes into the leather outfit. Harry grinned and a bed appeared. Hermione pushed him onto it, "The things I do for you my love."
"I'm the luckiest man in the universe," he responded, pulling his shirt over his head.
-Time Jump Forward-
Knowing that the two kids trusted them to finish what they'd started six adults moved to help. After some discussion Dan and Emma decided to just end their dental practice when they moved. James had easily found two homes that were connected and paid for them both, letting Dan pay him back after the sale of their former home and practice went through. It was imperative to the magicals that they be away from any home that Dumbledore could find. Their new houses were heavily warded by Gringotts and by Remus, Sirius, James, and Lily.
James quit being an Auror after they'd rounded up all the Death Eaters. Sirius did as well and the two began an effort to make werewolves recognized as equal citizens and to remove the old pureblood-favoring laws to give Muggleborns and half-bloods more rights. Lily, in the meantime, focused on the kids and researching the laws with Emma, finding loop holes and drafting new legislation.
By the time Harry and Hermione were five James and Sirius had managed to accomplish those goals. They had inducted Dan into the Marauders shortly before Hermione's third birthday, and so they began to try and plan what they would do now. Working in the Ministry didn't appeal to either of them anymore, nor did Lily want a job that took her from home. She was adamant that they spend plenty of time with Harry and she found working from home would make that the most feasible.
Granger Potter Electric (GP Electric for short, which induced groaning from both women and the kids) was a company unlike any other. James liked the non-magical world, so he saw no problem with simply altering muggle brilliance to work in magical homes. That was where Emma and Lily came in. And Hermione and Harry, once they were old enough. Both had retained their abilities, making them able to still cast wandlessly and wordlessly with ease. Emma and Dan were the purchasers of the items and would take them apart to figure them out along with Remus. Once the electrical components were isolated then Lily and the kids took over, altering them to run on magic using runes and charmswork. It was a very successful business, making washing machines, dryers, refrigerators, air conditioners, and even hot tubs all run in magical homes. Muggleborns proved to be their biggest customers, though half-bloods really enjoyed those things as well.
Then the kids had pointed out that video games were huge and would continue to be huge and only get bigger and better. Since all four Marauders had put money into GP, they also all put money into a new company, LB (to which Emma, Lily, and the kids groaned again) to handle personal electronics like gaming systems, stereos, televisions, phones, and computers.
As they grew up they became close to Luna Lovegood, Neville Longbottom, and Susan Bones. All three had, in the previous timeline, always been loyal to the couple so Harry and Hermione had made sure their parents were close with Frank and Alice Longbottom, Susan's aunt and guardian Amelia Bones, and Xeno and Selene Lovegood. They both remembered how Luna had been teased at Hogwarts and didn't want that to happen again. When Selene's accident in the lab had happened Sirius and James had been there quickly, pulling her out and ultimately saving her life.
Their inability to save Susan's parents was difficult to swallow, but she had a wonderful aunt and the kids often all played and stayed at the Potter and Granger residences so that helped ease their burdens. Indeed, Emma and Lily often watched all the kids while the others worked. Remus taught them all occlumency when Harry turned nine and then Harry and Hermione told their friends the truth. Telling their three friends was crucial, in Harry's eyes. Hermione had been more hesitant but she had to admit, it would be easier to get them away from Dumbledore if they knew the truth. Harry and Hermione had used the pensieve to offer proof and after the expected shock had come and gone the couple found themselves engulfed in a hug from Luna for saving her mother's life. Neville followed given that their information had led to swift Ministry action and while his parents still had to fight Bellatrix this time they'd been backed by James, Sirius, Lily, and Remus. The Longbottoms had not been injured or even harmed thanks to the support of their friends.
Susan was relieved that Harry and Hermione had managed to prevent Voldemort's return which would have led to her aunt's death. She too had joined the hug and the couple had breathed a sigh of relief. That had made the five of them closer than could have been expected. Not wanting to keep their parents/guardians in the dark Harry and Hermione consented to letting them know. Xeno felt highly indebted to the two who had saved his wife's life while Selene was just happy they'd looked out for Luna and defended her from bullies. Frank and Alice had both promised to always do whatever it took to help them and Amelia offered the same support.
When Harry turned ten their parents sat down and discussed their relationship with them. Harry and Hermione were both of the opinion that they were still married and they both promised to not have children (or get married again) until they were at least legal adults (18). Hermione saying that she'd wanted to wait until they were in their twenties before starting their own family had all four parents relaxing. Lily offered to make the contraception potion when they were ready for it and Harry instead chose to let all four magical adults teach him the contraception charms he already knew. He couldn't handle the awkwardness of his well-meaning mother making his girlfriend and wife's contraception potion, but he could let them ease their worries by teaching him the charms.
Albus Dumbledore found himself the target of an investigation after Voldemort's death. His assertions that Voldemort wasn't dead fell on deaf ears and when Severus Snape implicated him in various things that just skirted being against the law he found his position on the Wizengamot and then his position with the ICW yanked. James Potter had asked crucial questions that Dumbledore refused to answer, claiming he was acting 'for the Greater Good' and so his actions were above reproach. A stern-faced Barty Crouch took the opportunity to rip into him about endangering people and it was soon whispered that Albus Dumbledore was quite possibly going senile.
The wizard decided to bide his time, determined to coax Voldemort out of hiding to prove he was right. Then everyone would turn to him for help and begging forgiveness for calling him senile. In his infinite wisdom and with his gracious nature he could forgive them for their transgressions against him. He might get even more titles. He'd get Potter and Longbottom once they were at Hogwarts. Their parents couldn't do anything then.
