Prologue

The day started as any other normal day, well as normal as a day can become when you are in hiding from a self-styled Dark Lord and live in a place that no one can even see, unless they have been given the secret. All because of the Dark Lord in question believes a prophecy that a baby could kill him.
Around midday the secret keeper himself came around, a Peter Pettigrew that had been a friend of James Potter since first year of Hogwarts, wanting to show the couple something on his new car that he had parked up front.
Not suspecting anything, Lily and James followed their friend out front. As Peter opened the car, turned it on and then begun showing them all the strange radio channels it could receive James was suitably impressed, never having really been in the muggle world and with the Wizarding Wireless having just arrived a few years ago, and then only with a single channel. Lily herself just rolled her eyes at the antics of her Pureblood husband and friend.

While the three were out front, another person, Lord Voldemort, was sneaking into the house from the back. The reason for not wanting to confront the married couple being that he had faced them three times before and at none of the times had he managed a clean victory, the times had ended in more of a draw with both sides retreating.

Once inside the house Voldemort quickly found the room where the Potter children were napping in and not wanting to risk being discovered before he finished his objective he quickly drew his wand and fired a killing curse at the closest child. He was just beginning to adjust his aim to prepare for another killing curse at the second child when his eyes widened in fear, seeing his curse being reflected back from the first baby and heading strait back at him. With the short distance and his surprise even he had no chance of avoiding the returning spell.
Being his own spell and that he had delved into immortality further than any other living person the curse did not act the same way that it would have done on any other person, instead of killing him and sending his soul on to the next plane of existence the curse tried attacking the binding between soul and physical body. As the tension increased the first thing that gave was the body of the Dark Lord, in an explosive release of unrestrained magic the body disintegrated using up some of the force, the remaining magic travelled in a sphere around him in an explosive shock wave tossing the crib aside and blowing a large hole in the wall of the room exposing it to the outside.
The crib, that had been in the Potter family's possession for generations had been charmed to withstand any and all accidental magic that toddlers could accomplish, protected the toddlers from the majority of the shock wave and only shook the previously sleeping children awake before the powerful magic on it fizzled out.

Outside Lily and James Potter turned around in a start as the wall on the second floor of the house, the wall leading to the room that their children occupied, exploded out and showered them with small pieces of wood. As the parents desperately raced towards the house to check on their babies they both heard the crack of apparation as Peter left, though this was completely dismissed as unimportant compared to their own children.
Entering the house and rushing up to the children's room they are just getting the twins to stop crying when Albus Dumbledore enters the room. After hearing what happened from James he quickly casts a number of diagnostics spells to determine what went on inside the room before the explosion.
Discovering that Voldemort has been reduced to a shade and that the killing curse cast on Helen and then reflected back is the cause he explains to Lily and James that Helen is the Chosen One from the prophecy.

Dumbledore tries to convince the parents to give up Harry so that they can focus all their attention on Helen and that keeping Harry would just grow up to become jealous of his sister for being the target of a prophecy. After almost half an hour the parents are just about ready to throw Dumbledore out on his behind to stop him when he sighs deeply and says, "I had hoped it would not come down to this. But this is for the best, both for Harry and Helen." As James and Lily look at him strange his wand flashes up and he intones "Obliviate" twice so quickly that the targets of the spell can't react.
Dumbledore modifies their memories so that they believe that Harry died in the explosion that was the result from the Dark Lord disintegrating and that they asked him to bury the body in the Potter family plot in the graveyard by the local church. He gently takes Harry from James arms and leaves.

Sending a Patronus message to Minerva McGonagall, his Deputy Head Mistress, that he has to take a month off for personal reasons he leaves the country.
Starting in France he monitors over a dozen magical orphanages all over Europe to find one where he can be sure that he is taken good care of. After the month is almost over he decides that one in France is the best one, there he anonymously leaves the boy with only a note saying his name is Harry. That having been taken care of and assured that Harry will have a good childhood he returns to Hogwarts with a clean conscience, knowing that Harry will most likely never come in contact with the Potter family and so will never be thought of as their dead child he puts Harry out of his mind to focus on more important things.

Chapter 1

Helen Potter, according to herself has great parents and has had a great childhood, even though she has always had a feeling in the back of her head that something is missing from her life, something very important. Before going to Hogwarts at eleven years of age, she has, at her mom's insistence, gone to the local muggle school. In school she has had a few friends, though nothing special, and she was close to the top in most of her classes. She was never much interested in the sports they had at the school but despite that she was always happy to be jogging through the forest behind her house several hours a week.

When she received her Hogwarts acceptance letter a little before her eleventh birthday she could not wait to go. She had heard stories from both of her parents about their time there and did not want anything more than make her own memories of the place. When September first finally arrived she asked them to take her to King's Cross by car instead of by floo, the way that most Pureblood and halfblood are taken, because she remembers what her mum told her about walking through the 9 3/4 barrier and wanting to experience it herself.

When passing the barrier at a slight run like she was told she runs into a girl standing right in front of the barrier, having forgotten to move because of all the sights of a new magical place. Helping the other girl up, who introduces herself as Hermione, they immediately strikes up a conversation comparing the differences between a muggleborn and a magic raised child. Instant friends they almost forget to say good bye to their parents as they help each other to stash away their school trunks.

The train ride passes quickly with just a short break to go find a boy named Neville's toad. As they walk to the magical school together with all the other first years and Hagrid the Keeper of Keys they both marvel at the sight of Hogwarts. The sorting places both of the friends in Gryffindor which they are very happy about.

Helen and Hermione gets into a friendly rivalry over who does best in all the classes while Helen helps Hermione tone down her 'know-it-all' attitude a little and not show her eagerness in answering all the questions herself. Having a friendly rivalry, with focus on friendly, they have nothing against helping each other where needed, which helps both of them get better.

They arrange to have both their families together when they come home for Christmas and spend most of the holiday together. Having a best friend like Hermione almost makes her forget about the emptiness she has inside her but when she lies alone in her bed the feeling always returns, even though she has learned to mostly ignore it by now.

Back at Hogwarts the best friends continue to amaze their teachers. With the obvious skill difference between the two friends and the rest of the first years they don't have many friends but they don't mind, they have each other.

As it starts drawing up to exams the friends starts wandering around the school any time they can to just quiz each other on the material they have gone through to make sure they are both ready. During one of their walks Helen is pushed aside and into a wall by a running Professor Quirrel as he tries to pass them by quickly. Helen shouts out in pain at a burning sensation in her neck and the Professor starts stumbling after running just another couple of steps.
Professor Quirrel falls to his knees holding the hand he used to push past Helen in front of his face, staring in horror at the hand that is slowly crumbling to dust.
Just moments later Head Master Dumbledore arrives at the scene in pursuit of the DADA Professor and sees as the last parts of the body in front of him crumbles and the shade of Voldemort tears himself from the now dead body he had possessed. Seeing the shade raise above the pile of ashes Dumbledore gets out of his shock and hurriedly banishes the malevolent spirit from the school with a quick exorcism spell.
Talking to the two children the Head Master finds out what happened and after a short explanation to them the two friends agree with Dumbledore's request to keep what happened quiet and to let Dumbledore explain it for their parents after school lets out for summer.

Without any surprise, Hermione and Helen are at the top of their year, though despite Helen's efforts she could not match Hermione's score at the theoretical and even with all the practice Hermione has done she could not get the same high scores on the practical exams. Despite all they are both very happy both for their own scores and their friends'.

Dumbledore's explanation to the two friends' parents gets him yelled at for a while but after he gets to finish telling what happened they understand that he could not have done much to prevent what happened.

The summer passes quickly with the two friends spending as much time together as they can and when it gets time to board the train back to Hogwarts they arrive at Kings Cross together.

The second year passes in a frenzy of school work and extra curricular learning for the two best friends, all the way up to Halloween, when the caretakers cat is found petrified under a message threatening the muggleborn students of the school. No one could understand what the cat had to do about it though, as the caretaker's parents were both Pureblood and the cat was a Kneasle.

A few weeks later Helen found a diary belonging to a 'Tom Riddle', not knowing anyone in school by this name and with the bad feeling she was getting from the diary she and Hermione brought it to their Head of House, Professor McGonagall. Shortly before going home for Christmas that year the two friends was
called aside by McGonagall and was thanked for having brought the book to her, she told them that the book was cursed and had been destroyed. They left after having been given a dozen points each for their service to the school.

Very little of note happened during the rest of the school year, and after the exams had taken place they had the same standing in their year as they did the last, Hermione leading the theoretical side and Helen the practical.

Third year passes without any notable events.
