Hogwarts: What are the four great masters doing?

"And powerful wizards may be able to choose whether or not to step into that realm, into the kingdom of death."

"The existence of ghosts may also stem from the boundary between life and death - their powerful obsession allows part of their soul to remain in the world of the living in the form of reflection."

When Ryan was still alive a thousand years ago, Ravenclaw had already begun research on the boundary between life and death, but had not yet achieved any results.

But judging from what Helena said today.

After he left, Ravenclaw apparently made some breakthroughs in this regard.

So that she could somehow save Helena's soul from the vortex of death.

What Ryan didn't expect was...

"I don't know how my mother did it, but I'm sure... the reason I'm able to stay here is related to the castle."

Helena said so.

"castle?"

So Ryan was really surprised.

"Hogwarts?"

"Ah."

Helena nodded.

Then, in front of Ryan...she gently stretched out her hand and lightly tapped the ground of the astronomy tower next to Ryan.

The next moment, Ryan saw with astonishment that a wall had appeared out of thin air from the ground of the Tianwen Tower beside him.

It grew naturally from the ground and stood next to Ryan.

Torches were hung on the walls, and the standard patterns common to Hogwarts were engraved on them. Even Ryan couldn't tell any difference from the real castle for a moment.

And more importantly...

"This is..."

Ryan's eyes widened in surprise.

"No trace of magic..."

That's right.

Just now, Helena stretched out her hand and lightly tapped, and this wall appeared out of thin air.

From beginning to end, he didn't detect any trace of magic.

It was as if there really was such a wall in Hogwarts, but it had only "grown" out at this moment.

This made Ryan look at Helena in surprise.

And when Helena saw the look in his eyes, she naturally had no intention of hiding anything.

"I don't know what kind of spell this is."

She explained seriously.

And Ryan quickly understood.

Simply put, since Helena turned into a ghost.

She then discovered that she could manipulate Hogwarts Castle itself.

She could create a wall from within a wall, she could stop a staircase that was constantly changing and moving.

And all this is not transfiguration or other similar spells.

But it is another kind of magic that is difficult to describe.

"That stems from Hogwarts itself, Brother Ryan."

“I felt a connection with it—I can’t quite put my finger on it, but I think it was something in my soul,” Helena said.

She said.

"I'm sure the Barrow's ability to transform into a ghost has something to do with that, and another entity in the castle that's related to him is Peeves."

"Peeves?!"

Ryan was indeed a little surprised when he heard the name.

But he quickly reacted: "You mean..."

He also thought of a well-known fact in the school - Peeves was lawless in the school, but it was said that he was only afraid of the Bloody Baron and Helena.

But thinking about this...

"Speaking of Peeves—his treatment of me is because of you, isn't it?"

Ryan just remembered that he hadn't asked about this yet.

That's right.

After realizing that the mysterious letter was sent to him by Helena and hearing that Peeves had been staying with Helena frequently recently.

He had already realized why Peeves had treated him so strangely last semester.

It now seems that the mysterious ghost's fear of Ryan was most likely due to Helena's warning.

"Ah."

Helena naturally didn't hide anything. She nodded and said, "I was the one who told it to stay away from you. Ever since the incident with the three-headed dog—it went too far there and almost got you hurt."

"Hey, have you forgotten who I am?"

Ryan said helplessly: "It's just a three-headed dog. I've dealt with it before. You shouldn't doubt it..."

Boys always have their own subtle self-esteem.

After hearing this, Helena glanced at Ryan helplessly.

"Of course you can handle the three-headed dog, but you're still too small. Look at your height—last year you were barely taller than Peeves."

She thought about it, but ultimately decided not to say such hurtful words.

"Anyway, I think the reason Peeves is afraid of Barrow and me is probably because of that subtle connection between us and the castle... Barrow and I can even touch Peeves with our ghostly bodies."

"Have you asked him why this happened?"

After hearing this, Ryan also frowned.

"I asked—and he said he didn't know."

Helena shrugged her shoulders when she said this: "According to him, he would be instinctively afraid when he saw me..."

After hearing this, Ryan more or less understood what Helena meant.

These days he had also asked Helena about the origins of Peeves.

As undoubtedly one of the oldest ghosts in the entire Hogwarts, Helena did give Ryan some clues.

She said she was certain that Peeves did not exist, at least until she left Hogwarts.

Coincidentally, Peeves appeared at the exact time when she turned into a ghost - Peeves had already been in the school since she woke up as a ghost.

Ryan naturally understood the meaning of this.

"Helena's case and the Bloody Baron's case must have been the work of Mr. Ravenclaw and Ms. Hecate—they may have made a breakthrough in soul magic while researching the curse."

"They used this breakthrough on Helena and the others. Judging from this, it might also be related to Hogwarts Castle."

"Peeves happened to be born during this time."

And coincidentally...

"According to Dean Olivia, Ms. Hecate's disappearance should have been around this time."

That's right.

The transformation of Helena and the Bloody Baron into ghosts, the birth of Peeves, and the disappearance of Hecate Alanthel—all three events likely occurred around the same time, and possibly for the same reason.

And Ryan is almost certain at this moment...

The treasure left behind by Ravenclaw must be related to this incident.

However, when he asked Helena about the treasure...

"I don't know, Brother Ryan."

Helena obviously didn't know about this.

"In fact, I was also surprised when I heard about the treasure - and it wasn't until last year, after seeing you retrieve the Hufflepuff professor's treasure, that I was sure they really existed."

She said so.

After hearing this, Ryan thought about it and didn't find it strange.

According to his current speculation, the treasure of the four giants should have been left to him specifically to deal with the threat from the other side of the curtain.

As far as he knew, anything that happened on this side of the curtain would have a corresponding reflection on the other side.

It seems that only wizards who have entered the realm of legend can be immune to the influence of this reflection.

Helena obviously did not meet this condition, so it was not surprising that Ravenclaw did not tell her about the treasure.

but...

"If my mother did leave behind a treasure, I think she would have left it in the Room of Requirement."

Although she didn't know the details of the treasure, Helena made such a guess - she obviously knew about the existence of the Room of Requirement.

"No, I've been to the Room of Requirement."

Ryan shook his head: "I don't think it's in there."

The first thing he did when he returned to the castle was to go to the Room of Requirement to investigate, but in the end he found nothing.

But speaking of the Room of Requirement, Ryan naturally thought of another thing.

"I saw the teacher's crown inside..."

He naturally asked Helena about the crown.

Because he had already seen it in Bloody Baron's memory.

When Rowena ran away from home, she stole the Ravenclaw diadem.
