Chapter: 2

Severus was currently outside of Hogwarts, in his home, he was still resentful with Albus Dumbledore and the Dark Lord Voldemort. He knew that he was not fit to teach, and yet he was a teacher at Hogwarts. He still have a promise and vow to keep, for Lily he will keep strong. As he was making sure that everything was in order he heard a knock on his door. It was insistent. He was annoyed that his time was interrupted, but the person knocking seemed to not want to leave, with no other choice he went to see who it was. With a scowl on his face he open the door, just in time to avoid another round of knocking. The person knocking was a young woman, wavy red hair that was cut just below her chin, a green dress that reach down to her ankles reveling white shoes, her white coat was wrap around a younger figure that she was carrying on her left side were a white purse was hanging from her elbow. The young figure was a child that was currently sleeping, but what caught Severus attention were the woman's green eyes, they were void of emotion, they were empty, like if their owner was hollow and numb. Severus barely manage to hold in the shiver that treated to run through his body.

"Sorry to interrupt but I need some potions, I will pay if necessary, can I come in? I will explain everything, I need a place to let my charge sleep while we talk" the red-haired woman said, there was something in her voice and eyes that made Severus curious but at the same time wary of her, her voice was as detach and hollow as her eyes, with that he step aside and the woman enter his home. He guided her to a guest room where she left her charge. After the child was secure they move to the living room were the woman sat while Severus prepare some tea.

"What it is that you wish to discuss?" Severus ask as he handle a cup of tea to his visitor

"I need to perform a ritual to brake some spells that are place in my young charge, I need some potions to fix what the people did before I kidnapped the child, from the abusive home the kid was living in, I need someone that has very strong mental barriers, and I need someone to trust and help me. Someone I can tell the truth without having to worry about being betray, someone to help me plan my revenge, and someone who has seen both sides of conflict, you are not who I expect, but you are the closest that I can trust" she answer after taking a slip from her tea

"You dance around the issue as if you know me"

"In a sense I know you, but I don't know you as well"

"Do you want me to make a vow?"

"No, I trust you enough"

"That is foolish considering that I do not know you"

"You are to call me Rotanev, what I am about to tell you is the truth, if you do not believe me you can look into my mind"

"Are you so desperate that you will allow me to pick around in your brain?"

"Yes"

"Very well, tell me your story, Rotanev"

"It would be easier if you saw my memories"

"Fine" agree the Potion Master, looking directly into the green eyes he let himself be pull to the memories that the woman in front of him was insistent of showing him. The woman show him most of her life as Harry Potter, the abuse by her supposed family, her trials during school, the boy begging the headmaster to stay in Hogwarts and not be send back to his relatives, the philosopher stone, the Chamber of Secrets, the attack to the train by the dementors, the story of Sirius Black being innocent. The tournament during fourth year, the blood quill in fifth year, Sirius's death, the prophesy, his book about the half-blood prince, Dumbledore's death, the hunt for the soul pieces of the Dark Lord, Severus own death, the transfer of memories, the battle for Hogwarts, the defeat of Voldemort. The hunt for dark creature, and Harry's own death at the hands of Ginny. Once he finish looking and processing what he had just watch, he look at 'Rotanev' for a more detail explanation

"You have some questions, I will try to answer as much as I can"

"You want young Harry to not have the life that you did"

"That is right, when I lived as Harry I did not know of the spells that my mother put on me, I also didn't know that I was not James Potter's son, but Regulus Black daughter."

"Who is Rotanev"

"Rotanev was Lesath Riddle non identical twin sister, she died about a month ago, and when I died, Death gave me the opportunity to change things. In order to do so I was given my aunt's empty body."

"So lily was adopted by the Evans, she was not muggle-born right?"

"Indeed, her real name was Lesath Meissa Riddle, daughter of Tom Marvolo Riddle a half-blood and Meissa Lynx Black, the squib daughter of Marcus Black. Tom Riddle Jr, you know him better as the Dark Lord Voldemort. Rotanev Tamara Riddle was transfer to an orphanage in the United States were she attended Ilvermorny."

"What is the history behind Regulus daughter?"

"Her name is Heka Mimosa Black, she is bonded to Bartemius Crouch Jr. and is the heiress for the Black family considering that Regulus is dead and Siruis in Azkaban. Heka is also the heiress of the Potter family in case of the death of Harry Potter, Lily trick James into agreement"

"You met Barty during your fourth year" Severus ask but there was curiosity in there as well, considering that she had just reveal the bond marriage that she had with Barty

"Yes, he was a good teacher, despite the fact that he was insane, it was because of my bond with Barty that love potions did not hold, and it was until his death that I became more influence by them. By the time I met him he was completely insane by his lack of treatment after he escape Azkaban and by being under the Imperious Curse for twelve years. At that time I was worry because of my attraction to him, I felt safe when I was around him, but I never got to question him, he bonded with me as Heka before he was send to Azkaban, but I didn't know why, he was also one of the three best Defense teachers that I had, it is thanks to him that I had an opportunity, I didn't know about our marriage until closely before I died as Harry"

"So, right now you are the Dark Lord's daughter, and Regulus's daughter is his granddaughter"

"Yes, I also found out that Tom Riddle had good ideas but Dumbledore's treatment and other set of circumstances basically drove him to insanity. There is a possibility to restore him as well as his sanity. However he will be younger than his true age. If I restore his body he will pass as my brother, hopefully he will help me with my retribution and restore the balance of magic."

"I was headmaster"

"You were, you use your position to keep the students safe, the reason why you lost said position was because you died, ever since then, I have being trying to get better at potions, I like the subject"

"What are your plans?"

"Kill Harry Potter, teach Heka Black, get a retrial for Sirius and Barty. Ruin Dumbledore's reputation. Restore father's body. Wait until Heka attends Hogwarts to get a teaching position. Help father with politics. Get revenge on the people that used me. That is why I need your help, once the spell is broken, I will need you to help me teach Heka and myself occlumency, you are her godfather, and I am her aunt, we raised her together. Her godparents are Alice Longbottom, and you. I claim guardianship base on blood"

"You want me to make sure your mental barriers are strong enough and to prove that your knowledge cannot be taken from your mind"

"Yes and no, my knowledge of the future is block by Death, the only reason why you were able to see them was because I allow you to view them"

"So now I report to you until your father is back in power?"

"Yes, it is surprising how well you are adapting. And how you are referring to Voldemort as my father not my grandfather"

"You were never Heka, and as Harry you didn't know about you relationship. Also you are in the body of Rotanev, his daughter, in all sense you are Rotanev Tamara Riddle"

"Once we free Heka, I want to go to Gingotts for the inheritance claim, I suggest that you take the Lordship of the House of Prince, I am going to wait until I restore Tom…My father's body to claim inheritance, I need your help to create the memories for Heka, once the spells and rituals that are holding her true appearance are broken, she won't be able to remember her life as Harry. The only reason why I remember was because I never lived as Heka, I died as Harry, but in death I was force to claim my true self. I explain things to Harry, but that won't matter, since Heka won't remember, especially when it will concern Tom Riddle."

"I better start with those potions, you can sleep in the guest room with Harry"

"Thank you"

"We need a lot to plan,"

"Thank you for understanding, professor"

"You are welcome, you made my promise to Lily much easier, but due to the circumstances you may call me Severus"

"Thank you Severus"
