Disclaimer: Not mine. Not ever.

He hadn't known the truth until Dumbledore's death. The old fool had arranged things for him to receive this damned letter seven days after his death. It was also the last time he had seen Fawkes. Even in death he was still using them for the greater good! How much time had he known? Knowing the man, certainly since the beginning! All could have been so different…

His own mother had taken from him the only thing that could have made him a different man. Out of pride! She had taken his other half, his blood, the one who completed him. He always felt like something was missing, without knowing what. As a child, he had put it on the fact that his parents were uninterested in him, even though it was something entirely different. His subconscious, his soul had identified her on her arrival to Hogwarts. He had felt like an old pervert then, but he couldn't prevent himself from observing her, trying to understand why his eyes were inexplicably drawn to her. He had then chosen to pick on her, to put her down every time he could and willingly let the students in his house to continue on this same path.

She was as different from him as day was from night. He inherited the severe traits of his mother and took nothing from his father, apart from his stature. His genitor had been a really handsome man, as handsome externally as he was interiorly despicable. She had his eyes and curls but had the heart as pure as his father's was corrupted. If his mother hadn't succumbed to this man's promises, who only wanted the Princes riches, his life might have been very different. No, if he had had his sister, his life would have been different, he knew it.

And now, it was too late. He had said too much, done too much. How could he explain that to her? His path had been mapped out and although he had chosen redemption decades ago, he was a murderer in the eyes of the world, a vile and lawless being, blindly following his master's orders. If they knew the one they believed him to serve wasn't the one he actually serves!

Whatever, it was too late now. He was going to die. He could feel his strength and his blood leaking out from himself. He will shortly join Lily, his dear sweet Lily. And later, much later he hoped, she would come and they would at least be reunited.

She only learnt the truth a handful seconds ago. When she had to bring herself to open the tiny box Dumbledore left to her along with The Tales of Beedle the Bard. He had bewitched it with the same charm that prevented Harry from opening his golden snitch. They ought to lose this fucking war for her to know the truth and gain the mean to change everything.

We lost.

This was the key that had opened the box, her very own Pandora box. Inside, she had found a sealed envelope, a leather-bound notebook, a pendant and a vial containing a strange glimmering potion. She had decided to read the missive and so found who she really was.

Dear Miss Granger,

If you are reading this letter, it means we unfortunately lost and Tom will reign on the world we knew. And with his reign, abomination and horror will come.

I know that when you will have finished reading these lines, you will hate me. Please do understand, dear child, that when I learnt what I am about to tell you, I couldn't do anything but continue to hide the truth from you, from you and another person. See, neither are you Hermione Jean Granger- you were adopted -nor were you born in 1979. And this is where your story gets complicated.

Your mother was a pureblood witch and your father, a muggle. You have to know she didn't have you adopted to protect you. No. Merely for revenge. You see in marrying your father, she had been disinherited by her family. Your maternal family is one of the rare matriarchal one of our world. In a marriage, the husband has to let his wife keep her last name and sign a contract in which he authorizes his daughters to bear hers instead of his. Although they had disowned your mother, they wanted to retrieve you. And the marriage of your parents being far from idyllic, your mother didn't want you to be happy and live the life she had lived herself. She then decided to abandon you and, to be certain that her parents wouldn't find you, used a very particular spell, sending you at the gates of a church, in the future.

Yes my dear child, you don't belong to this era. At least your age do not match with the one you should have. You were born on January the ninth 1960, and your parents are Eileen Prince and Tobias Snape. You are Severus' twin sister and your name is in reality Hermione Eileen Prince. I know this have to be shocking and I beg your pardon to have to let you know it that way. I have learnt your story by your grandparents when you disappeared. I have only known who you were when, as we do every year, we sent your first year admittance letter to Hogwarts. Minerva was the only other person to know the truth. Mind you, for every birth of magical child, his or her name appears in our annals. Yours was annotated with "born Hermione Eileen Prince". That's how we knew. We couldn't do anything and didn't want to involve you in the premises of a new confrontation with Tom. Even if later you befriended Harry and shared his burden. Severus had been my most faithful spy for numerous years and couldn't have protected you without risking compromising his position. I have kept him, too, in the dark.

I used all of you, in the sole purpose of permitting to the largest number to live. If you think I am nothing but a master manipulator, I plaid guilty. Nonetheless, all these calculi and plans were for nothing as you are reading this. I ask you to stop Tom while we can. Meaning the period you should have lived in. Although being a Transfiguration professor, I also am quite gifted in the art Severus masters. The vial in the box is an extremely rare potion from its ingredients, and a very difficult one to realize. It has to brew for five years. You have before you the famous potion created by Lucrezia Borgia: Verum Tempore. The time's truth.

This potion will lead you where you should have been. All you have to do is to drink it and choose which moment of this period you will reach. You have to know that, at the moment you drink this potion, you will create a copy of yourself, the one who should have existed in the concerned time. Your "you" will have lived another life, waiting for your arrival to close the time alteration created by the absorption of the Verum Tempore. Your two lives will then become one again. Know that when you'll arrive in your new reality, numerous memories will assail you. Those your being of this period will have lived. Those you should have lived. You have before you the only way to live the life that should have been yours.

The little leather book contain all the names of the death eaters of this period, the ones of the members of the first Order of the Phoenix and you'll have to continue to fill it in. I ignore what are the horcruxes created by Tom along with their numbers. Come to me if you ever need help and make me read this letter. The pendant opens itself and was charmed to always stay with you, even in this trip. He is provided with an Undetectable Extension Charm and you will be able to fit in it all of your possessions. You'll just have to use a Summoning Spell for what you need to come to you.

I am just an old fool, yet I hope you will forgive me to have kept all of this from you, giving you no other choice than leaving all you have known until now.

I hope to see you soon,

Albus Perceval Wulfric Brian Dumbledore.

P.S: I have always loved sweets, them being wizards or muggles.

It had taken her to read this to understand why her heart had been broken when he breathed his last. Severus Tobias Snape. Her brother. Her twin. They were yet so different. The two photographs were proof that Dumbledore was telling the truth. The first one was of two babies, both with the same serious appearance. The second one showed her parents. Severus had taken all from their mother where she looked a lot like the man whom was their father. And yet, having seen Severus memories, she knew his life had been hard. He could have been so much more if she had been there for him… She knew what she had to do and more important when she had to "arrive". The summer between their fourth and fifth year. Before Severus could make the mistake to call Harry's mother, his only love, the most degrading way that could be, out of pride. Pride that would lead him to lose himself and become a deatheater.

She would change all that!

Hello !

I hope you liked the 1st chapter ^^

So, what did you think of my twist ? I read a lot of Time Turner fic and I think I never saw Hermione being Severus' sister. This story already has 47 chapters in French as I am translating it from the one I am currently writing.

Merlin, I'm sorry for my English in this AN, I kind of murder it - -'

My beta, Shiroten, did a wonderful job so express your thanks to her :D

Anyway, this will obviously be AU and kind of OOC. Sirius and Hermione will not be together right now, it will take time.

So review please and let me know if you like it or not ^^

xoxo
