206 Harry Potter: The Walker family and the strongest Auror in history had appeared in the world.

Allen had not yet started the stream, so viewers couldn't see Allen arm in arm with Minerva.

Allen and Minerva walked through the Hogwarts Express corridors, filled with senior students, many of whom had astonished looks, unable to believe what they were seeing.

"Hey, the rumor was true!"

"No way, why is he here?!"

Minerva McGonagall chuckled, showing her white teeth and a mischievous gaze. "It seems the students are in shock to see you here, Professor Walker," she said as she approached Allen.

In response, Allen returned the smile and the flirtation. "I do not doubt that most of the looks are envious of having such a beautiful woman close to me."

Minerva's smile widened with a slight blush. "You're quite good, Mr. Walker. I suppose the rumors of you being a heartbreaker are true."

Allen narrowed his eyes slightly at her. "If you'd like to find out, we can have dinner sometime," Allen said in a tempting tone, causing Minerva to avert her gaze.

"It's somewhat inappropriate for two Hogwarts professors," Minerva stammered, searching for an excuse.

"Hehe, it's a shame," Allen didn't continue the flirtation and looked at the students who were peeking out of their train cabins with amusement. "I'm sure Dumbledore would have wanted to hide my arrival until the entrance ceremony in the Great Hall, but due to recent events, it's better if I'm on the Hogwarts Express."

Minerva tensed at hearing that; recent events had shaken the magical world. She glanced sideways at Allen, realizing that this man, who appeared to be just a young man and never aged, was at the center of the storm.

She sensed that dark times were approaching. They had all had a decade of peace since Voldemort disappeared, and it was rumored that he was dead, but now everything was starting again. Perhaps it was destined that the world would experience the rise of such tragedies every so often.

Allen reached a private train cabin and entered, but Minerva didn't follow. She stood at the entrance with an uncomfortable look. "I'll accompany you this far, Professor Walker," Minerva said with a slight reluctance to leave. However, her mission was to judge the character of Allen, the new professor, but she ended up getting involved with Allen more than she should. 'This man is very dangerous,' the woman thought.

As one of the most prominent witches in the magical world, she devoted her life to magic and had no interest in romantic relationships, yet the young man in front of her broke through all her defenses in a matter of hours and almost trapped her.

"It's a shame that I can't enjoy more of your company," Allen responded with a slight smile. He approached Minerva and, standing in front of her, took her soft, delicate hands. "I hope it won't be the last time you allow me to be this close, Minerva..."

Minerva blushed and coughed as she averted her eyes from Allen. "Yes, it's a shame... see you at Hogwarts!"

The woman disappeared from Allen's sight, or rather, she fled.

Allen remained silent for a moment, then chuckled with amusement and sat down. He closed the door with a wave of his hand and erected a magical barrier.

Artoria appeared in the compartment and said nothing as she sat opposite Allen, watching him.

"Well, it's time to start," Allen nodded towards Artoria. She would stay in the compartment while Allen carried out his plan. He stood up, his expression serious, drew his wand, and began to transform.

"Mutatio Aetatis..." Allen said.

Allen's body lost weight, volume, and musculature; his height decreased rapidly, and his age changed, and in a short time, he returned to being an eleven-year-old child.

Allen created a mirror with magic and looked at himself, then nodded satisfactorily at his original spell.

Even Snape had created a spell called "Sectumsempra," which made invisible cuts towards the enemy. Knowing that magic was not something definitive but something that was developed by wizards and witches throughout history, Allen decided to develop his own spells in this world.

One of them was Mutatio Aetatis, which means (age change) in Latin.

Allen smiled satisfactorily; this was not a disguise, he had literally changed his age. Of course, this spell has its limits; otherwise, it would make wizards and witches immortal, and in this world, immortality is not easy to obtain.

The limit, or rather the condition to maintain the age at which the spell changes you, is to constantly consume a determined amount of magic.

For someone with little magical capacity, this spell is almost impossible to maintain, but Allen can maintain the spell twenty-four hours a day.

But the real question is why did Allen become a child?

Allen decided to attack on two fronts: on the one hand, he would enter Hogwarts as a new professor to have authority and influence, and on the other hand, he would also enter as a student while the system forges fragments of destiny constantly being close to the main events.

"It seems my spell is very stable. How do I look, Artoria?" Allen asked with a slight feigned arrogance. When he didn't hear a response, he turned to see Artoria standing in front of him.

She had an intense look as she gazed at him, her breath strange, and her face slightly flushed. Allen hadn't seen Artoria with that expression before, and he felt strange.

"Artoria?... I don't know what you're thinking, but stop it!" Allen, being considerably smaller, felt in danger and backed away.

Artoria, for her part, smiled sweetly. ""Ara Ara~ come with Onee-chan, Allen~"

"What?!"

Inside the soundproof cabin, Allen remembered experiences with some ladies who considered him adorable to the point of kidnapping him... more than once.

...

Allen broke free from Artoria's embrace, who treated him like a puppy and used a portal from the system to go to Diagon Alley, waiting for Harry Potter to arrive. Years had passed, and he hoped Harry's life wasn't as miserable as it should have been.

Why did Allen help Harry?

The quick answer is simple empathy; as an orphan, he also knows what it's like to live without your parents. Despite Natasha being by his side, it's not as if he would simply forget his biological mother and father.

Allen simply has a weakness for a situation similar to his own, no, it was worse because he had someone who loved him more than anything in the world, and Harry was a servant at best.

Allen didn't have to wait long for Harry to appear with Hagrid. As in the canon, Hagrid bought his wand from Ollivander and went to Gringotts.

...

"The Philosopher's Stone..."

Allen watched as Hagrid left the bank; he had to take the Philosopher's Stone at Albus Dumbledore's request.

Allen had changed his opinion of Albus; it was said that the whole incident with the Philosopher's Stone in the first book was planned by Dumbledore, and it made sense.

Three eleven-year-old children had heart tests that were supposed to protect an object so ridiculously valuable that it could start a war.

The invisibility cloak was given by Dumbledore, the flute that put Fluffy to sleep, not to mention that the tests were designed so that specifically Harry, Ron, and Hermione would pass them.

Furthermore, was the most powerful old wizard so blind as not to notice that Voldemort was infiltrating right under his nose?!

Allen clicked his tongue; after ten years, he already felt part of this world, and letting an elderly man risk the lives of three children to test Harry's heart and put him to the test was foolishness.

'Should I arrest him?' Allen shook his head; ruining the canon in this way didn't benefit him at all. He needed to remember his priority.

His world was becoming more dangerous, he needed massive amounts of destiny fragments before some Beyonder appeared at his door.

Allen returned and looked at the crowd at Platform Nine and Three-Quarters. Originally, they were supposed to follow the canon, but he and Wednesday ended up affecting this world on a level he hadn't imagined.

"Look, he has white hair!... don't you think he might be the son of..."

"It can't be true, that father and son came to Hogwarts!"

Allen noticed that he quickly became the center of attention. He smiled with a bit of embarrassment.

[Host, is creating an identity as your own son embarrassing?]

'If you know the answer, don't ask!' Allen hid and waited a while.

Allen heard an owl and saw Harry Potter with Ron Weasley enter the station. The canon began, but he knew this time would be different because of his existence and the creation of the Walker family in this magical world.

...

...

Allen Walker existed for the last ten years...

Allen Walker, that unknown name, gradually grew in the magical world, leaving an indelible mark and creating his legend.

The first thing Allen did after getting a wand was to find a way to make money. Exchanging credits for Galleons was not a realistic method, as credits were more useful for other things.

At the suggestion of the Chat, Allen decided to sell some trinkets he could create with his powers (people still believed he was a mutant). In reality, they were low-grade system items, either by buying them or obtaining them from the chests that had accumulated to more than two thousand.

It was a brilliant idea, but what would the Ministry of Magic think if a wizard came out of nowhere and started selling magical items in large quantities?

In Harry Potter, everyone's magical heritage and past are highly valued, which is why people without it, such as Muggle-born people, are so despised.

Wednesday came up with the idea of creating a magical family that had moved from America and selling both in the magical market and the black market.

Allen was reluctant because this would imply changing a lot of history, but Makima appeared to help. Having been a figure of authority and administration in his world for so long, she had good experience in starting a business, whether legal or illegal.

Makima assured Allen that they would do business without affecting the world too much. Allen didn't completely trust her, but he decided to give Makima the benefit of the doubt. Wednesday also agreed, but she would be in charge, and Makima accepted without a problem.

Allen, for his part, would seek to gain influence in the Ministry of Magic, perhaps becoming an Auror.

This was necessary for his real plan to enter Hogwarts during canon history, either as a professor or as a student.

To be a professor, one needs the full trust of the Hogwarts staff and essentially Dumbledore's approval.

Allen had no background to back up his goodwill; that's why he thought about becoming an Auror. Nothing proves that you're not a Death Eater better than hunting Death Eaters, and the idea of a magical family didn't sound right.

The Walker family was born with Allen as a young heir who had to flee his country because a very powerful dark wizard almost destroyed them.

Wednesday would be his wife, although both looked like young people no older than twenty, their magical power and quick-wittedness quickly silenced the annoying voices of the closed and classist magical society.

Wednesday, with the help of Makima and Esdeath, delved into the dark side of the magical world, spreading their threads. Esdeath was mainly there to watch over Makima.

Allen, with Rebecca and Artoria, went on the "light" side. Allen decided to become an Auror for a while before entering Hogwarts as a professor. Rebecca and Artoria had the role of loyal vassals and were sometimes maids. There was a rumor that they were Allen's lovers.

Allen's path was very complicated because to be an Auror, he needed to be recruited, and for that, he had to excel at Hogwarts. As a result, he entered Hogwarts.

There were many taunts because wizards usually enter at eleven years old, and Allen was already eighteen. However, he showed extensive knowledge of magic that impressed Dumbledore, so he entered directly into the fourth year.

Allen crossed Hogwarts as an absolute genius, with top grades in all subjects and breaking a lot of records. Quickly, the taunts about his age and disdain for his origin quieted down.

There was no way to fail because he had many people knowledgeable about Harry Potter in his Chat, Gwen, Emma, and even J.K. Rowling herself. It was a surprise to see the author of Harry Potter in the Chat.

He felt this was as unfair as having Albert Einstein help you take a math test. However, the surprise was mutual because she didn't know many things about the world she wrote about.

This made sense, in a couple of literary sagas, it was impossible to talk about everything that could exist in a world as large as Harry Potter, assuming that its existence is a complete world with billions of years since its existence.

Discovering the contents of several vaults in Gringotts was just the tip of the iceberg; the author's jaw dropped at seeing Allen's wand, but after thinking for a while, she realized it made sense. Elves have magic even more powerful than humans on average, the World Tree is simply linked to all fictional elven legends.

...

Allen ended up skipping grades at Hogwarts thanks to help, the system, and his talent. In two years, he graduated with honors, surpassing Dumbledore's record. Some called him the next great wizard of the era.

To the surprise of many in the magical world and a bit of disappointment from Dumbledore, Allen became an Auror after graduating. He didn't broadcast this and decided to skip it to make it a surprise for the Chat.

Allen entered the Auror Academy and graduated in a year despite needing three. Soon, rumors spread; that a monster had been born among the Aurors.

The Walker family and the strongest Auror in history had appeared in the world of Harry Potter with force.

A/N: Obviously! to avoid trouble with the FBI Allen will not touch any girls like Hermione or Luna until the future...

I'll say it again, Makima is evil incarnate, but she's hot.
