From Azkaban To Hogwarts

"professor?"

Harry's shout startled William, causing him to wake up.

"It's okay, I have some bad speculations," William said. It's not good to talk too much about those dark things with students. Some of the things spread in Azkaban are too dark even in the adult world and are not suitable for students at all. touch.

"What about Banban?"

"It may have encountered some special things and needs to stay in my office," William considered how much information to reveal, "but no matter what the truth of that matter is, I can tell you with certainty that its injuries have been controlled. .”

As he explained to Harry, he summoned his owl and hurriedly wrote a note on the table.

"Go to Professor McGonagall's office, thank you for your hard work."

He tapped its beak lightly with his fingers and tied the note. William's owl flew to the window, jumped out of the window a few times, and then flapped its wings and flew out.

Taking advantage of the absence of Professor McGonagall, William quickly walked towards the mouse named Scabbers, trying to use this time to verify his judgment again.

Harry, who had no idea what was going on, didn't make a sound and just watched.

‘No matter how you look at it, they are just ordinary rats…’

William looked at the mouse carefully - after the treatment just now, its wound was already recovering steadily...

'wrong! Something is definitely wrong! "

William immediately discovered something was wrong. Under the effect of the seemingly overdose potion just now, the mouse's front paws did not recover!

The entire body is obviously growing, but the front paw that is missing a toe has no intention of growing at all, as if it is born empty and does not exist at all.

'dark magic…'

As a self-defense professor, William immediately made a judgment that only black magic could completely erase the existence of a limb so completely that recovery methods would be ineffective.

"How long has it been alive, Harry?"

William suddenly turned around and asked Harry.

"Sorry, Professor, I don't know exactly... but Ron has been raising him since the first year. He was Percy's pet before."

'It's not specific to Harry... it might even have been there before Percy entered school, the chance of it meeting Harry is so low that no one could have guessed it. ’

'Then, it is most likely to have been killed very early...'

"Oh my God! What happened here?" Professor McGonagall's voice came from far away, and then there was a sound of hurried trotting in the corridor.

After a while, Professor McGonagall appeared in front of the door that no longer existed.

She pointed her wand into the room with a slightly confused look in her eyes, "Are you okay, Professor William? And Potter, what's wrong with him?"

The story was too complicated to write in a note, so she was still confused.

"I'm fine, Professor McGonagall."

William tried his best to look like he was smiling, "I need your help with something. I have a terrible guess now, but I can't do anything about it."

"problem?"

Professor McGonagall was stunned for a moment, forgetting about the door that she had planned to continue asking about. She glanced at Harry in confusion, "What trouble did Potter get into?"

"No, what gave me a headache was a rat, a pet rat."

William shook his head and took a few steps to the table where Banban was placed, "That's it, Professor."

"mouse?"

Professor McGonagall followed him confused, and then followed William's gesture and looked at the table - over there, a mouse was unconscious and seemed to be seriously injured, but the wound was constantly healing and growing. He was given a valuable potion.

But what’s there to see in mice?

If the person who caused this scene was Gryffindor, Professor McGonagall even planned to treat it as a prank.

But she soon discovered something was wrong - this mouse was no different from a normal mouse in terms of hair, paws, tail, or anything else. It felt like a mouse, but it was not a mouse.

'A very clever transformation technique... almost deceived me...'

"I'm not sure, what do you think?"

Professor McGonagall didn't respond. She waved her wand, and several hairs fell from the mouse's body and floated into the air.

But nothing happened. The mouse's short hair finally fell lightly to the ground, motionless.

"Your guess is correct, Professor William."

Professor McGonagall took a breath and nodded, her expression also changed. "Although further research is needed to confirm which kind of transformation it is, there is no doubt that this mouse is not a mouse."

"Where was it found?"

Using the wand to pull up the mouse hair again, Professor McGonagall asked with a serious face.

"It's Ron's pet, Scabbers. It was injured today, and Hagrid suggested that I send it to Professor William for treatment..."

Before William could respond, Harry poured out all the questions as if he was frightened.

"Percy's pet and given to Ron?"

Professor McGonagall repeated her confirmation while waving her wand - a transparent cat came out of her wand, stepped on the air, and then rushed directly towards the wall.

Seeing this scene, even though Harry had always been generous, he immediately realized that something terrible had happened.

"It usually lives in the lounge?"

Harry was stunned for a moment, and then he realized from his surprise that the professor was asking him, "Yes, Professor, he has been living in the lounge since the first grade, especially this year it is in very bad condition. Staying in the dormitory The days will be even longer.”

"Then does it usually behave aggressively? Or, does it behave in a way that is not quite befitting a mouse?"

Harry thought about it seriously, "No, Professor, it just doesn't bite like an ordinary mouse, but that's the nature of pets."

"What about break time? What's the recipe?"

“…”

Question after question was thrown, and Harry had to think carefully before answering from time to time.

"Professor, it's me."

Percy's voice was filled with panic. He stood at William's doorless door and looked at the two professors inside with a slightly nervous expression.

"Come in, Percy."

William nodded at him, "Come here, do you know this mouse?"

"Banban?"

Percy shouted in surprise, "What's wrong with it?"

"It was a little injured. Harry sent it here, but it is still being treated. According to Harry, it was your pet before?"

"Yes, Professor."

Percy nodded and thought for a moment, "I've had him since he was very young. In total, he has been in our house for twelve years."

"Twelve years? Where did you get it from?"

"A pet store," Percy blushed. "There was a sale on rats..."

William also knew a little bit about the Weasley family's family situation, and he immediately understood that they bought Scabbers purely for the sake of cheapness.

"What about its toes? Why is one of its toes missing?"

"It was like this when I bought it...it was a little cheaper because the toes were missing..."

Percy blushed even more.

It all makes sense - deformation, cheap selling...

But he can't be allowed to go back. Although William is sure that it was not done by their family, it still depends on what Professor McGonagall says - just when he asked Percy, Professor McGonagall had already begun to detect what kind of deformation it was. Technique has led to such consequences.

“Unexpectedly…”

When Professor McGonagall raised her head, her eyes were full of rare surprise: "It's not human transfiguration... it's Animagus."

Animagus?

What kind of transfiguration is this?

Although he has been working hard to teach himself the art of transfiguration, William is still struggling with animal transformation, let alone the more complex human body transformation. As for the Animagus, which surprised even the transfiguration professors, William has not dabbled in it at all.

"Animagus?"

Percy was frightened, "But professor, didn't you say that there are only seven wizards who have mastered this spell in this century?"

Seven...

William suddenly understood why he didn't know it - even black magic is rarely so difficult that only seven people can master it.

"Obviously, this is an illegal Animagus, and the success rate of proficiency is very high." Professor McGonagall nodded, "I can even say that in terms of Animagus' transformation ability alone, he is better than I am strong."

'You can do it too...'

Although Professor McGonagall said it in an understatement, and William knew that it was unlikely that Professor McGonagall would not do it, he still couldn't help but feel that compared to other professors, he was just a salary thief who had sneaked in...

"Stronger than you?"

"Yes, I didn't even recognize it at the first time..." Professor McGonagall shook her head, "We have to find Albus. I can't forcibly lift this level without understanding the wizard's relevant information. Transfiguration."

"I'm leaving it to you, Professor William. I have to go to Albus's office in person."

Professor McGonagall nodded to William and quickly left the room. Because the door did not exist, her footsteps made a particularly loud sound in the corridor.

'The previous method of using the patronus to bring messages was good, you can think about it - but why did Professor McGonagall go to the principal in person? Are you afraid that if you don't know clearly, the principal will pretend not to be in school? ’

Knowing that it was not a human body deformation, William was suddenly in the mood to joke, and he even made a little joke about the two principals.

Being imprisoned by someone and being controlled by one's own transformation magic are two different things. The former makes people feel sad about the death of a rabbit, but the latter just...

"How difficult is Animagus? Azkaban is all about human body transformation, but as Professor McGonagall just said, Animagus is more difficult than human body transformation. Seven people in a century... Hogwarts Take two…”

Although Professor McGonagall didn't say that Dumbledore was an Animagus, William directly acquiesced that the principal was good at magic - it was strange that Dumbledore didn't know it.

"Professor? So, Banban was turned into a mouse?"

Harry finally asked after hesitating for a while - he was not stupid. Based on the discussion between the professors and the conversation with Percy, it was too easy to come to this conclusion.

"That's basically it."

William nodded - it doesn't involve erasing memories, illegal imprisonment, etc. This matter can still be discussed, after all, the impact is not that big.

"Then, was it made like this by bad guys?"

Harry hesitated and continued to ask.

"Can't confirm..." William shook his head. At first, he was also affected by the sad mentality of a rabbit dying and a fox dying, but now that he was distracted, he thought of more things.

"You have to know, Harry, don't believe in things that are sealed easily, especially if the other party is intelligent." William looked at Percy again, "You must also remember it, Percy."

"Learn to judge for yourself instead of accepting what is said by sealed people and things. Even if there is truth serum, it is very easy to lie. You can even tell only part of the truth and mislead you elsewhere."

"So, it was a bad guy and was turned into a mouse?"

Harry still didn't get it.

"Learn to judge. We know nothing now. Everything must be based on reality. Blindly relying on first impressions is the most unreliable thing."

William emphasized again, "But we will have the results soon, the principal and others are here."

Just as he said, Dumbledore and Professor McGonagall soon appeared in front of the doorframe, both of them looking extremely serious.

Human transformation is dangerous enough. A wizard who was turned into a mouse for twelve years is simply a horror story. Even though Dumbledore has experienced the era of two Dark Lords, he still rushed to William's house without saying a word. The office is coming.

"Professor William," Dumbledore said with a serious expression, "I need to see that mouse."

He didn't even have time to say hello to the other students before he walked directly towards Banban, and then stared at it for a long time, carefully looking at the healing wound and the still missing front paw.

For a moment, William even thought that Dumbledore was about to wave his wand to end the difficult transfiguration, but after a long time, Dumbledore still did not raise his wand.

"Albus?"

"I can't remove this magic," Dumbledore shook his head. "Human deformation is dangerous enough, but Animagus is even better than it."

"If it were just human body transformation, even if it failed, I would still be confident that the situation would not worsen. But Animagus is different. There are too few wizards who have mastered this magic. Even if I have dabbled in it myself, I have not cracked it. confidence."

'Is there anything Dumbledore can't do? ’

William was stunned for a moment, and then immediately thought of the high-end aspects of this magic - seven wizards in a century, counting the eight wizards in front of him, mastered it...

This level of magic would be a real joke if it were cracked.

"I have to take it to my place, Professor William." Dumbledore nodded towards William, and then looked at Percy, "I'm sorry, Weasley, after confirming that it is a wizard, you can't take it anymore." Now that I have kept it as a pet, I will try my best to crack the Animagus."

After learning more about how Scabbers came to Weasley's house, Dumbledore took Scabbers away.

Harry left William's office with a look of disbelief on his face. As for Percy, he was taken away by Professor McGonagall to try to learn more about it.

'The door needs to be repaired...'

William glanced at his office door, shook his head, cast several protective spells on the office, added an illusion spell, and then set off for Filch.
