Just a Defense Against the Dark Arts Professor

When Sherlock woke up, he was already lying on a bed in the Hogwarts hospital.

Although there is no strong smell of disinfectant here, when you open your eyes, you will still see a vast expanse of white.

"Very nice, I like white very much."

This was the first thing he said cheerfully after waking up.

"It seems that the mood has not dropped yet."

A dull voice sounded next to him.

Sherlock tilted his head and saw Hilke sitting next to him.

"Oh! What a joy it is that we have emerged from the underground!"

Silk shook the bell in front of the bed for him and called Madam Pomfrey over.

"You are happy enough."

"Don't keep a straight face, Hilke. Be happy. We have to laugh. For example, right now, I feel great about myself! I'm in such good shape that I even feel like I can continue to be happy like this!"

While Sherlock was chatting about very happy topics, Madam Pomfrey came over with a bottle of potion.

"His condition is indeed as you said, a little over-excited." Madam Pomfrey once again confirmed Sherlock's current condition with her own eyes. "It's a bit like drinking too much joy potion."

"This bottle of grief potion should be able to help him suppress it, but I'm a little unsure of the exact amount." Madam Pomfrey said tangledly.

Sherlock shook his head happily.

"Sadness Potion? I don't want to be sad. Isn't it good to be happy? Why should I make people sad?"

However, no one would take his words seriously. Madam Pomfrey studied Sherlock's current state for a while, finally determined the dosage of the potion, and then personally supervised him drinking the entire bottle of Sadness Potion.

Hilke did not leave, but stayed with him beside the hospital bed.

After drinking the potion prepared by Madam Pomfrey, Sherlock's condition significantly eased. The smile on his face gradually faded, and he could communicate with others normally.

"It seems that you should be careful when using this kind of Patronus Charm in the future." Sherlock said with a headache.

Although the overflow of positive emotions is not a big problem, even without Madam Pomfrey's potion, he can only be happy for a week or two and get better.

But if something like this happened during a key battle, it would still be very troublesome.

Just when he was feeling a little depressed about this, Sherlock suddenly discovered an old locket around his neck that had never been there before.

"What is this?" He took the dark gold round locket and said with a frown.

Silke also noticed this thing at this time.

"Didn't you take it with you before going underground?" Her tone became slightly serious.

Sherlock shook his head.

"No, I've never seen this thing before."

He tried to take the locket off his neck, but found that he couldn't do it!

It was as if there was an invisible barrier on his body, blocking the chain of the locket between his neck and head. No matter how hard he tried, he could not remove it.

Sherlock's expression became serious.

He was no longer trying to take it off himself, but looked at Silk.

"Is this thing from that straw man?"

Silk also realized that something was unusual.

"No, it didn't have this thing on it when it escaped."

Suddenly, she seemed to have thought of something.

"Its power relies on fear. If it were in its heyday, it would not be as weak as it is now. But after escaping to the UK, all its actions were very low-key, and it did not mean to spread fear to restore power. Came directly to Hogwarts."

"It's looking for something."

Sherlock looked down at the locket hanging on his body and tried to open it, but failed.

There are obviously no latches on the box, but there is no way to open it from the outside.

"Is it possible that this thing is what it is looking for?" Sherlock said dullly.

I don't know why, but his mood suddenly started to get worse again, feeling a little sad and a little lost.

He looked at Hilke.

"Can you tell me now what that straw man is?"

Silk said calmly.

"This is the top secret of the German Ministry of Magic, and it has also been the main subject of research and supervision by the Department of Mysteries for the past hundred years."

When Sherlock heard her say this, he thought she was refusing, but unexpectedly, she continued.

"Its name is Fiddlesticks, and it originally came from the island of Azkaban."

"Azkaban?"

Sherlock's eyebrows rose.

The original owner is an expert in studying dark creatures, and the most famous dementors are his main research subjects.

Dementors and Azkaban are almost symbiotic existences.

Azkaban is now the most notorious wizard prison in the wizarding world, but in the beginning, it was actually just an ordinary island in the North Sea.

In the early fifteenth century, the island never appeared on any map, neither Muggle nor wizard.

Until one day, a wizard named Extis of unknown nationality came to the island, built a castle here, and lived here alone since then.

After Extis came to this island, he had gone crazy.

His magic is extremely powerful, and he often conducts some extremely evil black magic experiments, and takes pleasure in seducing, torturing and killing Muggle sailors who pass through here.

At that time, the Ministry of Magic was only a prototype and had not been truly established. Only the Wizengamot, the wizarding court, weakly managed the magical world.

Azkaban, which was far away from the main British island, naturally did not receive their attention. It was not until after Extis died that the hidden spell he set on the island failed, and no wizard discovered the island.

But it is already filled with hundreds of terrifying monsters that can suck people's hope-dementors.

This is the earliest relevant record of large-scale gregarious dementors in the history of the wizarding world.

The island was later used by the Ministry of Magic as a prison for wizard criminals, and all the dementors inside became jailers.

But the relationship between Dementors and the Ministry of Magic has never been an employment relationship, but a cooperative relationship.

The existence of monsters like dementors is completely anti-human.

It's not that the Minister of Magic has proposed to destroy the island, but the island can be destroyed, and the dementors cannot be completely eliminated.

They were afraid that these monsters would escape to the British mainland and cause even greater trouble.

So it was the perfect solution to build it into a wizard prison, actively send prisoners to the island, and let the dementors eat to prevent them from escaping.

It can be said that that island is the most evil place in the magic world in the past hundred years.

"Before the British Ministry of Magic set up a prison on the island, someone explored the island and brought out an evil soul - Fiddlesticks."

Silk said softly.

"It itself has no fixed form, but when necessary, it can create an entity on its own, which is what the straw man looks like."

"It is more terrifying than the Dementor. The Dementor only feeds on hope, but it wants to create fear. It takes pleasure in devouring souls full of fear and becomes stronger by doing so."

"In Northern Europe in the eighteenth century, it caused a series of tragic massacres. In some places, even an entire town of Muggles was killed by it."

"Reciting the death words of the dead is its greatest pleasure, and torturing the living with their most fearful words is its favorite game."

"The scarecrow with a sickle in one hand and a lamp in the other was the most widely circulated horror story among Muggles during that period."

"Until one day, a powerful wizard defeated it, only to find that it was impossible to kill it. He could only capture it and bring it back to the newly established German Ministry of Magic."

"Since then, Fiddlesticks, the demon who manipulates fear, has been imprisoned in the Department of Mysteries of the German Ministry of Magic, guarded by the Silent Man. To this day, I am the one guarding this demon."

"But it actually never stopped resisting. During the nearly two hundred years it was imprisoned in the Ministry of Magic, it secretly accumulated strength until it escaped four months ago."

After Sherlock listened to Silk tell the whole story, he felt even more sad.

"After being imprisoned for more than two hundred years, the first time I came out was not to think about how to escape without being caught, but to find this thing. It sounds like it is troublesome."

At this time, Silk discovered something was wrong with Sherlock's emotions.

"The amount of potion in that bottle seems to be a bit too much for you."

She rang the bell again and called Madam Pomfrey over to check on Sherlock's current state.

"How are you feeling now?" Madam Pomfrey asked seriously.

Sherlock replied weakly.

"It's not great. I feel terrible. There's no point in watching anything. I feel like I don't have much time left and I'm going to die."

Madam Pomfrey nodded with satisfaction.

"Fortunately, the sadness potion is not too much, it's just that I feel like I can't survive. If you feel suicidal, I will feed you some joy potion to neutralize it. It will probably take less than a week now. Recover naturally.”

Sherlock left the hospital depressed.

"It's very possible that this thing was found in the goblin's abandoned headquarters. I can ask the ministry to contact the goblin I've communicated with before. Maybe he may know something about it."

Silk and Sherlock separated in the corridor on the fifth floor.

He continued to walk to the third floor alone, planning to go directly to Dumbledore to see if he could help him get the locket off his neck.

Sherlock staggered down the stairs. At this time, the students had just finished class.

Last night, because Black broke into the Gryffindor common room, all the students in the school were arranged to sleep in the Great Hall for the night.

After the professors checked the entire castle to make sure that Black was not hiding in a corner of Hogwarts, the school returned to normal teaching order the next day.

When he walked slowly to the third floor, he happened to meet Harry and the three of them who had just finished class.

"Professor, where were you last night? Why didn't you come to the Halloween dinner? Did you know that Blake broke into the school last night?"

As soon as Harry saw Sherlock, he couldn't help but ask a series of questions.

Sherlock looked at him weakly and said sadly.

"Ah, I also wanted to attend the Halloween dinner, but unfortunately I missed it. As for Black breaking in, this is really bad news. Harry, it seems that you have not had good luck these two days. I am going to find Dumbledore has something to talk about. I don’t have time to talk to you anymore. Goodbye.”

After he finished speaking, he continued walking downstairs slowly and listlessly.

After hearing Sherlock's words, Harry froze where he was, and so did Hermione and Ron.

"Did you hear that!" Harry shouted in surprise after he realized what he was doing, "Professor, he said I haven't had much luck these past two days!"

Ron looked at him with envy.

"You are going to transfer Harry, and you will definitely become the luckiest person in the whole castle."

Harry looked longingly.

"The best thing I can imagine is Black getting caught and someone willing to sign my parental consent form to go to Hogsmeade for the weekend!"

Hermione frowned and said.

"Professor Forrester seems to be in a bad mood today."

"Although it's a bit bad to say this, if the professor was in a good mood, then we would have just said hello to him." Ron shrugged.

"Think about how to spend the next two days, Harry. I think you can ask if the Daily Prophet is holding any lottery events recently, and then sign up to win a grand prize."

They quickly focused their attention on this matter excitedly, and Sherlock also walked up to the stone monster on the third floor.

"I want to find Dumbledore. Can you inform me?"

The stone monster didn't speak. It seemed to have asked Dumbledore in the office in some way, and then made way for Sherlock to walk in.

Sherlock arrived on the eighth floor, opened the door and walked into the principal's office.

Dumbledore looked up at Sherlock and could tell at a glance that he seemed to be in a bad state.

"Are you in a bad mood? Sherlock."

Sherlock sat opposite Dumbledore, his upper body lying on his desk as if he were boneless.

"Madam Pomfrey gave me an overdose of the sadness potion, and now I feel really sad."

Dumbledore frowned slightly.

"I know you and Silk went out together yesterday, so what did you go through last night?"

In a sad voice, Sherlock recounted their experiences last night, and finally placed the locket around his neck in front of Dumbledore.

"Do you know what this is? Professor, or you can help me take it off my body."

Sherlock's posture on the table was just right for Dumbledore to pick up the locket.

He looked at the old, dark golden round locket, and his brows gradually became tighter and tighter.
