The residents of Privet Drive saw a flurry of activities in and around No. 4. Many construction workers were seen coming in and going from it, movers bringing in materials, rattles and clangs were heard for days as the house was refurbished. Meanwhile, inside the house, polarized emotions were observed. Helen would be seen calming watching and occasionally giving inputs whenever needed, but otherwise was seen with mostly a thoughtful expression, something one wouldn't find on a 5 years old. The workers were always confounded by her mature behavior and her inputs, which were well-thought and thus surprised them further.
On the contrary, Dudley couldn't believe what was happening. His parents, who till now would dance on his whims, were now doing the same for her and completely stone-walling him and ignoring his tantrums. Once when he was going to confront the girl, his dad had interfered and scolded him to never disturb her again.
He couldn't touch her in school too as she was the new favorite of teachers, and would report all his misdeeds back to his parents anyways.

Elder Dursleys' were completely under Helen's control. Vernon would go out of the way to get the best materials for Helen's new room. He oversaw the whole construction project himself and would be heard shouting loudly at anyone who made even a tiniest of mistake. He even had the whole house repainted when Helen mentioned off-handedly that the colors of her new room and the house didn't compliment.
Petunia had immediately taken her niece to the best boutiques in the area, where Helen had immediately taken a liking to fashionable dresses, skirts and clothes. Soon, both woman and girl were a regular sighting at various cloth shops in Surrey and even in London, whenever the latter grow out of her current vestures or just on her whim.

End result of all the work in the house was a beautiful room on the first floor with creamy peach color walls, a Victorian styled queen sized bed against the back wall, with satin sheets and a matching satty at foot. To the right of entrance door was a full length mirror, with shelves on either side. To the left was a walk in closet and the entrance to a private en-suite bathroom done in white tiles and marble. The remaining wall had huge glassed windows and a glass door that opened into a balcony where sunrise could be witnessed.

With her mind now being augmented and having Voldemort's memories, school became useless for Helen, but despite that she attended to keep her cover. Still she ended up being seen as exceptionally intelligent girl, who had a keen interest in modern technology and sciences as well as recent history and politics. Teachers and neighbors would describe her as fashionable girl who would always do something constructive with her time, be it reading heavy volumes in library, discussing latest policies with elders, helping her follow classmates, swimming in the local pool etc.

However, what they didn't know was that Helen never did anything out of the good of her heart. Every action had a purpose, and everyone was a tool for her use. She studied up modern technologies because Voldemort's knowledge about them was woeful and she realized that muggles had advanced too fast in the last few decades. They now had missiles with pinpoint accuracy, planes that flew faster then sound, satellites watching everything from the skies and computers with intelligence almost equal to human. She was specially impressed with mobile phones as they made letters completely useless.
The classmates she helped were either kids of influential people or had potential to themselves become one someday. She would help them in understanding subject matter or simply introduce to other potentials and they would be grateful to her, helped along with a subtle application of magic, making them forever indebted to her.
She charmed various powerful muggles with her political acumen and grace, making important contacts wherever she went.

Occasionally, Helen and her aunt would venture into the magical world. On their first visit, they bought up weekly editions of newspapers from previous years from the time when the dark lord fell to present as well as recent history books. Helen found about the fallout of that fated day, how she was famous all over the world for defeating the dark lord. She also found that the world thought Voldemort to be dead, which she knew from her memories to not be the case. She found which noble families had risen and fallen as the consequence of the war. Several Death eater families were sitting pretty after claiming imperious, while the most zealous followers of dark lord were in Azkaban. She learned of the losses the light side took, especially that of Alice and Frank Longbottom, her godmother and her husband. She also learned of what the great 'Leader of Light' Albus Percival Wulfic Brian Dumbledore had been up to, which was same old, same old. He was still playing his long game of chess, moving pawns here and there, her being one as well. Apparently, he had told the world that she was safe with caring family members. Helen scoffed, "caring, my arse" she thought to herself. Pausing, a smirk grow on her face, "well, now they are, so he is partially correct" she thought again.
She found out about Sirius Black imprisonment and frowned to herself. Voldemort's memories showed her that Peter Pettigrew was the traitor, not Sirius Black. Apparently, Sirius lost his cool and was outwitted by a worm. She shock her head, "Can't help him right now, will have to revisit this particular issue" she thought.

On her later visits to Diagon alley, she bought up potion books, a potion set and a few key ingredients to brew up nutrition potions for the damage that was done to her body, as it was not completely done away by her magic. She bought the books as Voldemort's potion knowledge, while adequate was not great. Soon, the last affects of the malnutrition was gone, giving her healthier skin, perfect eyesight and another inch to her height.

On her 11th birthday, Helen woke up with a smile on her face. She went out to the balcony to witness the sun already risen and soaked in the sunlight for a few minutes while brushing her hair. As she entered her room, she checked herself in the full length mirror. She found a beautiful girl of 11 looking back at her. She was of slightly above average height at 4'10" with slim figure wearing a night-suit of grey shorts and white spaghetti slip. She had a heart shape face, with arched dark eyebrows, almond shaped bright emerald eyes, small slim nose and full pink lips. Her 'famous' scar was now barely visible that too if one were to stand close and squint their eyes. Her black wavy hair were long, reaching the middle of her back, which appeared in red tint whenever the sunlight caught them right.
Smiling to herself, she went to the walk in closet to select clothings for her special day and started getting ready.
Thirty minutes later, a girl dressed in a floral sundress with brown calf length boots and light makeup descended down the stairs where her puppets...uhm... relatives greet her a good morning and a very happy birthday. As she sat down for breakfast, she thought about her relatives. Vernon was now the Vice-President at his company, which she arranged by influencing the right people, as a reward for his good work for her and also to keep up with her expenses. Petunia also had a state-of-the-art kitchen for the same reason. Dudley had by now thinned out and was programmed to the attack-dog of Helen, whenever she rarely needed such means.
"Good servants should be awarded" she thought to herself, as Petunia served her a healthy breakfast of eggs, oats and fresh juice.
Just as she finished her breakfast, a hoot was heard from the window. She looked up to find a tan owl sitting there with a letter tied to its leg. She smiled and called it to her. As it landed next to her, she gave it a piece of bacon from Dudley's plate and took the offered letter. She noticed her name written in Elegant green ink, along with her address accurate to her room. Amused she opened the letter and read through her acceptance letter of Hogwarts school of Witchcraft and Wizardry along with the shopping list. She had Dudley fetch a pen and paper and wrote her confirmation reply and gave it to the waiting owl, who immediately flew off.
She looked up to her aunt and said "We are going to Diagon alley". Her aunt nodded, got up and quickly cleaned up the table. Soon they left, her aunt driving her new Beetle to London. There they quickly found a place to park, and went to the Leaky Cauldron. Without making a fuss, they asked the bartender to open up the way to Diagon alley and entered the magical world.
There is went straight to the huge White marble building, the Gringotts Bank, run by the goblins. Finding an empty teller, Helen asked to be taken to her vault. "Name?" the Goblin asked. "Helen Lilian Potter" she replied neutrally. Arching an eyebrow, the goblin looked at her closely. Satisfied he asked "Does Miss Helen Lilian Potter has her key?". "No" she replied. Humming, he said "Then a new key will be issued to you if you would confirm your identity by a blood test". Helen agreed and the goblin produced a test sheet and a needle. Pricking her left forefinger, she let a single blood drop fall on the sheet, where lines began to appear. She handed back the needle absently noting that the prick healed itself immediately. The goblin after reading the sheet nodded to himself and produced a key for her, "Do you want the previous key to be disabled?" he inquired. After receiving an affirmative reply he directed the girl to the runner goblin.
Helen asked her aunt to wait and followed the goblin to the cart, which took them to her vault. On entering the vault she deduced that this was a trust fund vault and not the main Potter vault. Shrugging to herself she took out 1000 galleons which would be more than enough to buy all the items and various extras she was planning and still she would be left with enough coin to last a year.
Back out in Diagon they went first to the Trunk shop and bought a 4 compartment trunk with various safety features and a shrinking charm on it. Shrinking it to matchbox size, she pocketed it and continued on. They bought prescribed potions kit and ingredients as well as the telescope. They went to Flourish and Blotts and got the first year books and a few extra. Next they went to Madam Malkin's and got 3 set of Hogwarts robes of high quality. Helen also purchased several extra dresses and robes.
With one last item left they headed for the only Wand shop in Diagon Alley, Ollivanders. A bell chimed as they entered the shop, signalling the shopkeeper. An old man with wide, pale eyes came up and said, "Ah! Helen Potter. How have I waited for you to come to my shop? Oh, it seems only yesterday that your parents were here to get their first wand. your father favored a Mahogany wand, 11", good for transfiguration, whereas your mother paired up with a Willow one, 10 and a quarter inches, perfect for charm work. While I say favor, it is the wand that chooses the witch or wizard. But I digress, let us find you a wand".
For next half an hour Helen tried dozens of wands all failing to produce the perfect result. This however, didn't seem to faze the wandmaker out as he seemed ecstatic to have found a difficult customer. After a while, he paused with a thoughtful expression on his face, "I wonder" he murmured to himself and went inside the shop. He came out carrying a dusty box in his hands and opened it, presenting the wand inside to her. Inside laying on a cushion, was a light colored wand, roughly 11" long with simple light colored handle. As soon as she touched the wand, she know that this was it. Her Magic swirled around her and she felt pleasant warmth from the wand. Bright golden and red sparks emitted from the tip of the wand. "11 inches long, made of holly and possessing a single phoenix feather as core" Ollivander said. He continued "That phoenix gave only one more feather, just one, and it went into the wand that gave you that faded scar". Helen looked at him with her face carefully neutral. "You will do great things, Miss Potter" he stated, "after all, the owner of brother of your wand also did great things, terrible, but great". He paused and then with a smile said "That will be seven galleons".
