Prologue

Viola Potter was not sure what drew her attention to the files the Order had left behind at Grimmauld Place. It had, after all, been four years to the day since the final battle at Hogwarts, and three since her self imposed exile within the confines of the moldering town-house of Sirius's youth with nothing but a portrait and a house-elf for company. Over the years Viola and Kreacher had grown fond of each other. Although that had only started when she began learning pureblood etiquette from the portrait of Lady Walburga Black, however, Viola found that she did enjoy the lessons. The relationship was one of the few things that brought her any joy now. The only living human contact she had since she locked herself away from the world was Neville and Luna, and that was only because she had still tried to commit suicide on a regular basis. She stopped doing that after she found out they had put a charm on the house to alert them when she did try to kill herself, after all she had no right to take herself from their lives.

Neville and Luna had gotten married two years after the final battle. They were the only friends she had left, the only friends who were still loyal to her. The last time she had tried to kill herself was four months ago, on his birthday. Now she just spent all her time in the library soaking up magic that was like his, but not quite. And that was when she came across the files that had been left behind. Although, it was not until she was in the kitchen that her curiosity got the better of her.

Now she was rifling through the old files at the dining room table with Kreacher, muttering about blood-traitor's filth being left in The Most Noble and Ancient House of Black's. In her head Viola kept calling herself an idiot for dragging up things that would only bring her nothing but pain. Then she found it. It was black, nondescript, and yet sent warning bells off in her head. That should have been her first clue, the bells that came from the part of her mind that she dubbed her 'Slytherin self'. She had only started listening to it four years ago, as she watched that powerful snake-like man drop to his death.

The second clue was the fact that it was in Dumbledore's handwriting. She tried to avoid thinking about him, like she did a great many things, mostly because it was pointless to be angry at the dead. The third warning was that on the first page he had titled it 'T.M.R' and 'V.L.P'.

She chose to ignore the side of herself that said she would not like what she found inside of the leather-bound journal. The journal that reminded her of another, and through that memory of dark brown eyes and blood and burning in her veins and that blood-traitor, Ginny, lying prone on the cold floor. But no, those memories were too painful. Anything relating to him was painful. So instead of thinking of things best unthought-of, she turned to a random page of the leather journal and read the date.

'June 28, 1996,' just a few days after Sirius's death.

'Ronald and Hermione have just left my office in a rather shocked state, but they have agreed to the task I have given them. It saddens me, but if Viola lives after Tom's death she will have to either be isolated from the rest of society or killed. I hope for the former if she should live. Though I highly doubt that, after all only the strongest of people can live after the death of their soulmate, and while she is strong- she's not the strongest. Hopefully she will die, of course after she kills Tom, otherwise we might have to deal with an even more insane Dark Lord. It saddens me, but it must be done for the Greater Good.'

Viola's brain had stopped working, it could not be possible. She and Tom were soulmates? She had read about soulmates in the Black library upstairs and wondered how could he think such a thing. Surely she would have known if they were soulmates. She quickly turned to the front of the book to see if she could get a better idea of what that old coot meant. The first page was dated,

'May 18, 1980,

I cast a charm on both Alice and Lily that will show me the gender of each child. The charm also tells me if the children they bare have soulmates and if they do who also the names of the soulmates. Frank and Alice will have a boy without a soulmate, unsurprising as soulmates are quite rare, border-line myth. James and Lily on the other hand will have a girl with a soulmate. Tom Marvolo Riddle. Lord Voldemort. I did not tell them this, only that she will be a girl. I am upset that such an innocent girl will have to die. Luckily, young Severus Snape has come to me for help and in exchange I will protect Lily from Tom. In promising this I have secured a spy. Before he left I placed a confundus charm on him, that will affect anyone who enters his mind to see the Potters child as the greater threat to Tom. Knowing Tom uses Legilimency on his followers on a regular basis, this means he will go after his yet to be born soulmate. Killing both her and himself in one swoop. Of course this means, most likely, that both Lily and James will die as I doubt they will let Tom murder their child without a fight. I wish it were not so, but it has to be this way. For the Greater Good.'

Viola swore loudly, she could not believe what she just read. "That BLOODY Dumbledore had known, and he tricked us both into killing each other," Viola thought to herself. Dumbledore was the reason he came to Godric's Hollow that night. He knew her parents were going to die for her. He let it happen. "THAT BASTARD!" she exclaimed As if that revelation broke a spell, Viola shot out of the room, and the stairs, only stopping when Walburga asked what was wrong.

Viola stopped and stuttered, "Dark Lord—Me—Dumbledore –SoulMates," and with that she continued up the stairs to the library to find the book on soulmates, that she had earlier only skimmed. When she got into the library she ran to the furthest corner from the door and grabbed the slim pale purple book. The Blacks only had a little on soulmates, because in all their history only one of the Blacks ever had one. She quickly opened the book to the page she was looking for.

'Soulmates are an incredibly rare phenomena in which, two wizard's souls are compatible. The two soulmates can go their entire lives without meeting, but this will often make the wizards go insane. If one member of an acknowledged pair of soulmates dies the other's body will shut down from shock. Often they too will die anywhere from one hour to two days after the death of their mate. If a member of the pair dies at the hand of the other, even unaware, the one who killed the first member will fall into a black depression. In the end they will more than likely kill themselves.

If suicide does not happen they will quickly lose interest in the world. This will be like a living way to know your soulmate is a link between minds, the strength depending on the wizards magical core and the strength of the bond between them. Also if one has a genetic ability, like being a Metamorphmagus, then their mate will be able to use the ability, even if they have not yet met.'

"Oh Goddess, what have I done? Tom, oh Tom, please. I am so sorry. Please. I am sorry, Tom." These were the only thoughts running through Viola's head as she fell to her knees, sobbing. She stayed like that for who knows how long, just crying and begging for the dead man's forgiveness. After a while she stopped sobbing and got up, she went to where she kept her wand, not having moved it from where it fell from her grasp when Neville tore it from her hands four months ago, and with only one thought on her mind. The thought that she would soon be able to ask Tom's forgiveness face-to-face. She picked up the phoenix feather-core wand and pointed it to her heart just as the Floo activated, bringing Luna and Neville through. She looked at their faces and smiled as she said her last words.

"Avada Kedavra." And all went dark.

A woman with curly black hair, and eyes the color of the curse that took her life stood in the center of a big white room, glaring. Suddenly she yelled, "Come on, someone. Tell me what is going on, so that this can hurry up and I can go apologize to Tom, please."

"It would be better if you rather listen to me first before doing anything else, mistress," the voice said from behind Viola. She whirled around and stared. The voice belonged to a rather handsome looking man with long dark hair and solid black eyes- no whites, "Hello, Mistress. I am Death. You can call me Thanatos."

"Death, great, that's just great. What do you want?" Viola asked exasperatedly. She was tired and just wanted it to be over and now Death was preventing that.

"I don't want anything, at least not yet. You see, you died Mistress of my Hallows and that means you get a choice. You can either die here and go to the afterlife that awaits you or you can return to the moment of your death-"

"I choose the first one. I have no right to live after what I did to Tom," Viola answered without hesitation, as tears formed in her eyes.

"You didn't let me finish. You see I like you and your soulmate, so you have a third choice. You can go back to the day that you first used your mate's magical ability, parseltongue. So, you would return to the morning of June 23, 1991 with all your knowledge of the future."

Viola turned her back to Thanatos as she thought over his offer. On one hand she would see Tom again, whole, well not completely whole, but alive. Yet, on the other hand Tom would not know that they were soulmates and would try to kill her, and she did not know if she could handle all of that all over again. A thought popped in her mind, and she could not stop herself from asking, "What's in it for you? After all, no one ever does anything just because they like someone."

"Caught on to that, did you? You are right there is one thing I need you to do for me in exchange for sending you back. It's complicated and will require you to put in years of effort. You see if the timeline continues on the path it is on then the Muggles will soon discover magic at a global scale and make the Inquisition look like an afternoon picnic. There is also another reason I am doing this. You see if things had gone as planned originally then you and Tom would have met at Hogwarts in 1938, but you see the body your soul inhabited died just a few years before then, and souls can only be reborn again after forty-five years. So because of this, Fate and I decided to go on with plan B. Which didn't work, because someone decided to meddle. Guess who?" Thanatos explained letting all of this sink into Viola's mind.

"Dumbledore." Viola replied, in shock over everything she had learned and so she latched on to the least perplexing thing.

Thanatos nodded, "You see Dumbledore was not supposed to hear the prophecy, in fact only Snape was to hear it, which would have caused Tom-boy to go after the Longbottoms. In plan B you would grow up normal and happy, despite the war going on. You would have met Tom at sixteen, when you accidentally got lost in Knockturn Alley. From there you two would have courted for about a year when he would have told you everything and you would have joined him and put the Muggles under magical control. Which is what I still want you to do now."

"Why do you want Muggles under control. I mean, they are just Muggles. So why?"

"I prefer wizards, and I hate seeing them killed by those lesser than them. I have seen Muggles bring destruction to magic before and I don't want history to repeat itself." Viola nodded, deep in thought. She thought long and hard, well it seemed long as time had no meaning here.

Finally, Viola sighed, "I wish to go back." Thanatos smiled, as pleased as the cat that caught the canary.

"Good, I just need you to sign this." He handed her a parchment that basically said she would do everything in her power to stop the Muggles from destroying the world. Viola signed and she knew Death no more.
