I don't own Harry Potter, and this is a new story for a new year. Happy New Year.

Please let me know what you think.

I got this story idea from Through the Looking Glass, Darkly, by Esm3rald but it is my own idea and completely different.

Through the Mirror.

Two Worlds.

Holly was nervous as she walked through the supermarket. It was hard for her to be here, and it was even harder for her to cope with being with muggles. Every time she looked at them, she felt physically sick whenever the subject of magic was brought up.

She hated this.

She hated having to fight.

She hated having to hide like this.

But soon everything would change.

"….the Prime Minister claims the war against the freakish wizards is continuing apace. Already several magical schools in America, Japan, China, and France which were hidden during the first years of the war have been unveiled, and the children inside have been killed. According to records, some of those children come from non-magical stock-"

"About time!" A girl called from her position in the check out queue. Her cry garnered mumbles and yells of approval.

"It's too bad those children couldn't have been spared from Satan's touch!" Another woman, an older and one who was clearly more of a religious bearing commented.

Holly ground her teeth while she went about the supermarket, her fingers itching to take out her wand and slaughter every one of the….the filthy muggles in the supermarket for what they were saying.

But she knew better than that; with the magical detectors that the muggles now possessed, she would find it hard-pressed to fight them off. She wouldn't be able to return to her home and continue hiding. But it was hard for her to keep her cool.

Children had just been slaughtered by muggles. Some of them were muggle-borns. But what sickened her the most was how the muggles here and likely all over the damn planet thought it was some kind of sick game. Holly valiantly tried not to show any kind of emotion, but it was hard for her not to shudder not only at the fate of those children, who were magical, but because she knew precisely what was going to happen to their families. Ever since magic had been discovered as being real, the muggles had become better and better at detecting it once the initial breakthrough had been made. Those families would be interned into concentration camps where they would be experimented upon for any signs of any magical genes while it was expunged, but nine times out of ten, they would be slaughtered. All to purify the species.

She took a deep breath and she went through the supermarket to get basic supplies of food, and she fingered her rations book. Rationing had come back into the fold three years before when the magical world had lashed back out, using terrifying curses on the muggles. Food was scarce in both worlds, and so ration books had been reissued like this was the Second World War, all over again to cope with the shortages. In Holly's mind, the strike had been one of the smartest moves the magical world had made. But in her case, it merely made her more vulnerable and every time she walked into the muggle world while she kept her powers a secret, Anastasia was just waiting for the day when she was revealed as a witch.

Fortunately, she was able to finish her shopping and take it all back to her home. On her journey, Holly saw more signs of the war. She had been living in London for 7 years since she had returned from abroad on her travels around the world following her escape from the magical world and after Voldemort's death. While the buildings were still striking, showcasing the centuries of British tradition and history. But now there were differences as if London had travelled back in time to the 1940s, showing more signs of war.

Holly wondered if the PM was loving this. She guessed the bastard was. But as she looked around, Holly felt sad. Some of the buildings had been burnt to the ground, or demolished; the dragons and the trolls that had been brought in as physical weapons of war had inflicted enormous amounts of damage on London, but Holly knew there were other cities worldwide that had suffered much worse or much less than London had.

There were airships flying overheard bristling with guns and magical detectors. Holly glanced at them for a few minutes before she averted her eyes. The sight of the security patrols with soldiers who were armed with anti-magic weapons filled Holly with dread. She knew there was a chance they would stop her at the checkpoints.

One of her biggest nightmares was of herself, going through these patrols… only for them to shoot her dead.

The good news was muggle technology hadn't yet broken through the barrier where they could detect witches and wizards without them using magic, but that wasn't much of a consolation.

Their technology was developing at an impressive, frightening rate. Holly prepared for the ID check. As she walked closer to the checkpoints, she took in the food lines choked full of tired starving people who couldn't afford any decent food. Holly wasn't going to do anything to help them. After the way they had murdered so many of her kind, Anastasia wanted nothing to do with muggles.

She let her mind go blank while she walked over to the police officers at the checkpoint.

She approached a tired-looking police constable. He looked absurdly young. "Where are you going?" He asked.

Holly hated encounters like this. Some of the people who ran through these patrols took advantage of the post to transform it into something out of a Gestapo or KGB handbook.

When she was younger this type of horror was alien to her, but now they were so commonplace she'd found the best way to deal with them was to just deal with them. "Richmond."

"What was your reason for being here?" Holly was relieved the muggle was as upset as she was by the questioning. Ever since the Prime Minister revealed the existence of the magical world to the entire planet, the whole country had become a giant concentration camp. The muggle in front of her was likely one of a small number of people who hated what kind of depths they were falling down into while others were thriving under the regime.

One of the worst of the changes to the country was not being allowed to travel anywhere, and do what they wanted, without someone demanding why they were even there.

"Shopping; some of the shops in London sell wares I can't get in Richmond. And I went shopping for books," Holly opened her bag to reveal what she had in there.

The muggle constable took a cursory glance. He took a stamp and he stamped the ID book. "Okay, move along."

Holly just nodded and walked on her way. But on her way back to the Tube station, she received a horrifying sight. A young man was running away while three men, just as young yelled out. "WIZARD!"

Instantly the crowd backed away, some of them jeering while the boy yelled out, his face terrified, "NO, NO-!"

But it was too late. A soldier reacted instinctively and shot the boy down. The boy screamed in pain as the bullets tore him to shreds spraying the surroundings with blood. The three younger men's reactions were shock and horror. Holly growled under her breath. She knew what had happened just by looking at the muggles who'd jeered the other kid on. The boy wasn't a wizard at all. The stupid fools had been playing a sick joke, but they had either not realised the consequences or they hadn't cared and were just shocked by what they'd seen. It wasn't unusual. She had witnessed this kind of thing often enough to see that. What made it worse was the muggles just did not learn. Sadly it was a scene that Holly had come to accept as part of everyday life.

So many people were taking advantage of the modern-day witch hunts to blame and accuse their rivals and enemies of having magic. A lot of it was just petty, useless stuff that was worthy of muggles and human beings in general. Others, like these boys who clearly thought yelling out wizard was a laugh without realising what the consequences would be, were blind to the realities. But what made it all worse and sick in Holly's mind was while the muggles claimed they were wiping out the abomination that was magic, they were destroying themselves with their witch hunts.

Holly did the only thing she could. She left.

It was a relief for her to get home and put the food away, although if her plans worked out the way she hoped they would then she would never have to see anything like that ever again. She went online and checked her drop shipping business which sold t-shirts. She nodded to herself; she had discovered dropshipping a long time ago when it first came into practice, and the muggle internet made it really easy to work from home. It had been a business for her to get her teeth into when the internet first came about and as technology had improved, her sales had really gone through the roof while she bought her current home with a cross between the money she had stolen and what she'd inherited from her parents and Sirius.

Holly made herself a cup of tea (or one of the new substitutes that she had been forced to make do with instead of camomile tea, or mint; her favourites) and she sat in the living room while she looked at the collection of books in front of her.

She took a sip of her tea and saw that her hands were shaking. But then every single trip into the muggle world was harrowing.

Holly thought back on her past, thinking that the Dursleys, her muggle relatives on her mother's side must have been loving every single moment of the war believing it right that the 'freaks' were being wiped out. Thinking about the Dursleys…., well they made Holly think about her past.

Back in the 1930s, a woman named Merope Gaunt, a squib from a pureblood family which had fallen onto hard times with their obsessions into blood purity had developed a crush on the son of a muggle squire, Tom Riddle. Merope had used a love potion to ensnare Riddle and she soon became pregnant and she took Riddle off of the potion to reveal the truth, believing that he could love her. To her surprise and horror, Riddle rejected her and didn't hide his hatred for magic. Merope, abandoned and hated, made her way into Muggle London to give birth to her child, a boy in an orphanage.

The child was named after his father, making him Tom Marvolo Riddle. Merope died in childbirth, an act that would convince her son when he was older of how useless love was.

Riddle was a magical prodigy, but he hated the orphanage. Holly would never truly work out if the bastard was physically abused or if it was only mental and psychological abuse, but what she knew was he was justified in his hatred towards muggles, whom he saw as beneath him from the word go. They hated him because they knew there was something odd about him. Indeed, Riddle was somehow able to gain some basic control over his powers. And then he received his Hogwarts letter. Hogwarts was one of the oldest magical schools in the world, and it had links with Riddle.

One of his ancestors was responsible for founding it. For seven years Riddle was educated in the ways of magic. He was an exemplary student and everyone praised him for it. All except one teacher. Albus Dumbledore saw through Riddle mostly because of the impression Riddle had given him on their first encounter since it was Dumbledore who met him and showed him that magic existed. At the time Riddle had shown his assertive and domineering manner, and also his contempt for everyone but himself. Dumbledore watched over him for those seven years, really worried about him and his path, and while Holly despised Dumbledore herself, she knew he had a good reason to be wary about Riddle. Not only had Riddle attacked the muggle-born students at the school by setting a giant snake on them, but a girl had also died and on his departure from Hogwarts he disappeared.

Years later Riddle returned after delving deeply into the depths of magic knowledge to make himself immortal. He had decided to split his soul using a ghastly and sick ritual where he would perform murders and hide the split pieces of his soul into artefacts. At the same time, Riddle remodelled himself as Lord Voldemort. Forming a sick cult full of witches and wizards who joined him either out of fear or a genuine desire to see a pureblooded world order although Holly had quickly determined over a couple of years that Voldemort had no intention of doing anything like that.

Voldemort had always wanted power. He had seen the pureblood supremacists as the best means of spreading fear, terror and destruction. He had hated muggles. No doubt about that. But there was only one way that he would want to become the greatest wizard in the world. If he massacred every witch and wizard in the world, to say nothing of muggles, then he would be the only one alive and in his delusional mind, he would live forever.

And he had come close to conquering Britain. Granted, when she had done her research and discovered how far Grindelwald had come in just two years rather than a couple of decades she had found Riddle wanting. Riddle had only succeeded in spreading fear and terror, ordering his followers to launch vicious attacks that were so senseless it did not even come close.

In her later years travelling before everything fell apart, Holly had seen dozens of memories used in schools in Europe and indeed in America that showed Grindelwald; the man might have been a Dark Lord, but he was powerful and charismatic.

Voldemort?

Oh sure, he might have had something, but he was nothing more than a thug. But there was no doubt he had been successful in some areas. He had managed to bring Britain to its knees, and he had endangered the Statute of Secrecy. Thinking about that last point had her frown and grimace at the same time. She was in two minds about how Voldemort would've reacted if what was happening how had in fact occurred so long ago (she would not think about what the Dursleys would and could have done to her, especially since they had tried to kill her when she was 6), on one hand, she suspected he wouldn't have admitted making a mistake, but at the same time, he would likely have taken full advantage of the pureblood's stupidity in some way.

The wizarding world had been on the cusp of falling. The aurors were finally authorised to shoot to kill - perhaps the wisest move they had, she really would never understand Dumbledore's need to meddle in that corner - but the move had come too late. The Death Eaters were gaining ground every single day, launching so many attacks so many families were being massacred which made her wonder if the Death Eaters were even aware of what they were doing.

And then Voldemort had attacked her.

He was blasted out of his body.

Granted, it wasn't her fault or something she had done.

A year before she was born, a woman whom Holly would learn to hate to the point where she actually gave her poison that would work in two parts whereas on their own they would be virtually harmless spoke of a prophecy of a child who would become a 'savour' against Lord Voldemort. Holly sneered at the thought of the prophecy; it was hard to believe that something so stupid could have such an effect on anyone.

But Dumbledore had believed in it. No surprises there. Although at the same time Holly had occasionally asked herself if Dumbledore had only believed in it because it gave him some means of forming one of his stupid plans that were too badly thought through, there was little chance of something not going wrong.

Because the prophecy stated the only way a child could defy him would be if they had met and won three times, Voldemort had hunted her family down and he finally tracked her thanks to a traitorous little coward whom she had later tracked down and made sure he understood the depths of his mistake when she cut him up and started taking out his organs in chunks not much larger than a postcard.

With the magical world heralding her as the 'Girl Who Lived,' Dumbledore had taken her to her mother's muggle family after her parents were murdered. Petunia and Vernon were disgusting bigots, typical of the type of filthy muggle animal that she had seen every day for the last 3 years. And they had taught their son Dudley how to be as disgusting and prejudiced towards anybody not normal or 'un British,' which spoke volumes of their desire to see beyond their weaknesses.

For a long time, Holly was their slave, they treated her like shit because of her magical heritage. For a long time, she wondered why they hated her before she was nearly murdered by them. After that Holly swore to have nothing to do with them and to find a way to escape them when she could…

She shuddered as she thought about how they had tried to murder her, but she pushed that aside; compared to what happened to her later, that was nothing. Like Tom Riddle, Holly had discovered some rudiments of her powers early on, and she used it to magically bring stuff like food and water to her all in the comfort of her own cupboard under the stairs.

And then she had discovered the letters between Mrs Figg and Albus Dumbledore. Figg was a mad, batty, cat-loving old cow whom Holly later discovered was a squib, someone who could not do magic. Dumbledore had made her move to Privet Drive to watch over the young Girl Who Lived, and they exchanged letters. Holly found them when she was staying around at the woman's place. She remembered hating the stench of overcooked vegetables and cabbage in particular and the strong odour from the cat litter trays, but after that…well, Holly discovered a new reason to hate the woman.

Figg had known about the abuse, mental and physical and the attempted murder attempt.

Dumbledore had known about the abuse, mental and physical and the attempted murder attempt… and he had made sure she stayed there.

Figg was making sure she drank potions designed to inhibit her ability to learn, so Holly began to fight back when she discovered that truth and she had begun summoning antidotes to her to break the potions down until they were useless.

When she went to Hogwarts Holly was sorted into Ravenclaw, because she had begun showing off her intelligence in private and it worked for her in stopping Dumbledore's interference. For years Holly attended as a student, fighting Voldemort and Dumbledore. In her fourth year, she had projected proof of Voldemort's return to the masses. In secret, she discovered how to fight him later on. But her actions came too late. After Voldemort's final end, a new war brewing. And when it hit the magical world, very few remained to even know what happened.

The muggle Prime Minister had been a witness during the war against Voldemort, he had seen the terrible things the thoughtless bastard had done. For a few years, while Holly, oblivious to the danger, travelled the world and saw the sights while using her magic to steal and have fun in the meantime, she had been dealing with the problem of magic technologically. After 5 years he succeeded. The war had broken out all over the world. Barriers between the magical and muggle worlds were ripped apart for good.

Holly had never truly paid much attention to muggles, really. She had assumed with so much time where they could have grown, muggles like the Dursleys were not the norm. In truth, it was people like her mother's parent's who were the exceptions. Muggles simply did not and could never accept there were people who could do things and had a power they lacked.

Fear led to anger.

Anger led to hate.

Hate led to suffering.

Some of the muggles were afraid, others were angry. Religious muggles were the worst; they believed wizards and witches were demons in human form. It never even entered their mind they were murdering people who were just special. What amazed her the most was how the war had united humanity in a way anyone never thought possible - it was just so sad muggles had to use war to unite against.

But what was so sad was how there were muggles who were thriving in this environment; they were using this nightmare to accuse people who they hated, had a grudge against (God, she had assumed Snape was bad, but some were worse) and see them being led away or shot with magical dampening ammo. Nobody gave a damn if they were magical or not.

That was the cruellest thing imaginable.

Holly sighed. She was one of the few witches left still alive, everyone like her was in hiding although she had no idea how many of them there were now.

It was during a night where she had watched a movie (she might hate muggles, but she felt their entertainment was good) she stumbled across the idea of using time travel to change things, but her research as a Ravenclaw told her there were no time turners which could travel back more than a year or two, there was a law against having a form of time magic that could allow someone to go back more for a minute or a few hours because of the risk of paradoxes. That was not enough. She needed to travel back in time a long way if she was going to succeed.

She had a plan to travel back in time and change history, so then the war with Voldemort was so brief it was nothing more than a blip on the muggle's radar, or not even that.

But she couldn't do it without some form of time travel that would send her back a long way into the past. She had very nearly given up when she came across references to parallel worlds in the books from the Potter and Black family libraries. Worlds that existed out of phase with the rest of the universe, worlds similar and different to their own world. It wasn't exactly ideal since anything she did to change the world she travelled to would not change anything here. This world was finished.

But maybe… just maybe…she could save the magical world.

Holly sipped her tea. The ritual was going to be ready in another three days. She merely hoped she could hold her cool for that length of time.
