Tartarus

The news that becoming Werewolf, learning Fenrir Greyback, and that Squib could become a wizard was actually first told to him by Filch, a father he thought would never contact him until his death.

His father said that even he had considered becoming Werewolf to learn that magic.

In his view, Harry Potter in front of him was probably for the same reason.

After all, even his father, the head of the Rowle Family, one of the Sacred Twenty-Eight, couldn't help but be willing to temporarily become Werewolf, which was even inferior to Squib in his eyes.

Just as Filch was thinking of having the already extraordinary Harry Potter learn Fenrir Greyback first, and then having Harry Potter teach him as a condition, Harry spoke up.

"No, this has nothing to do with Fenrir Greyback."

"This has to do with Rowle," Harry said bluntly.

"I... I was just a Squib before..." Filch's face immediately filled with a mixture of pride and shame.

He hadn't expected Harry Potter to think so highly of him, believing that he actually knew Rowle's secret.

On the other hand, he was deeply hurt by his status Squib.

"I just want to know about Azkaban."

"You should know—" Harry interrupted Filch before he could finish speaking.

"On June 6, 1720, the great Minister Damocles Rowle decided to use Azkaban as a wizarding prison, with Dementors as guards," Filch said.

Harry could tell that Filch did it entirely subconsciously.

Filch seemed to have it ingrained in his DNA, speaking it so fluently and seamlessly.

"So why do the Rowle family attach so much importance to this policy?"

"Why did the Rowle react so strongly, even risking cursing him, when Edridge Diggory, as Minister for Magic, decided to choose a different location for the wizarding prison?" Harry followed up with his question.

Filch's performance just now undoubtedly gave Harry confidence in the possibility that Filch knew the secrets behind Azkaban.

"I don't know, but I do know one thing: every Rowle, as long as they are wizards, no matter how bad their grades are at Hogwarts, they are all skilled in a kind of Dark Magic unique to Rowle."

"I think this has something to do with Azkaban."

"When I was a child, my father told me that as long as Azkaban remained a wizarding prison in Britain, and as long as people believed that, it didn't matter even if there were no prisoners inside." Filch's facial muscles relaxed, and the memories of his childhood filled him with a radiant glow of happiness.

This is the expression Harry would occasionally show when he saw Filch and Mrs. Norris alone at night from his dormitory window, thanks to his enhanced eyesight.

"What's that spell called?" Harry asked eagerly.

He felt he was closer than ever to the answer to the mystery.

"I don't know, I'm just a Squib."

"However, as long as it's next weekend, it will be March, and I can get the Wolfsbane Potion and, under the guidance of the Ministry of Magic, become a true wizard in the middle of the month, at the full moon!" Filch was surprisingly not angry at being interrupted from his childhood memories.

It seems the joy of becoming a wizard has changed him.

On Monday, Charms Class in the afternoon, Harry and Ron, who had agreed to meet in an unused room at the end of the fifth-floor corridor, were pacing around in circles inside, waiting for Draco.

After an unknown amount of time, the azure sky outside the window turned a dim yellow, and Draco appeared with the sound of a heavy door closing.

His pale golden hair shimmered in the twilight sunlight.

"You're finally here!" Ron slammed his fist on the table in annoyance.

Because of the House-elf, the desks in these empty rooms remain spotless.

Harry looked at Ron's clean right hand and thought to himself for no apparent reason.

Perhaps it was because he had been waiting for so long that he was spending the time daydreaming.

"I'm sorry, I only just arrived because the news of my engagement got out."

"I finally understand how you feel, Harry," Draco said, clasping his hands together in apology.

He had previously become famous for mistakenly believing he was having an affair with Harry Potter, and he thought it would be the same this time.

He never imagined that the wedding banquet, which was delayed because of those Pure-blood Squib, would lead to the entire Wizarding World now knowing about his engagement.

Not to mention Hogwarts, where most of the Pure-blood students were already participants.

"Have you found out?"

"Rowle's secret and Azkaban's secret?" Harry asked, snapping out of his daze.

"Of course—I know!" Draco deliberately dragged out his words, keeping everyone in suspense.

"Just tell me directly," Ron said, twisting his neck in annoyance.

"Besides this, there's one more thing I want to say."

"However, judging from your expressions, you're probably more interested in knowing Rowle's secret first." Draco glanced at Harry and Ron's expressions.

"Harry, you mentioned to me at noon that you learned from Filch that the use of Azkaban as a wizarding prison was related to the talents of the Rolles and the Rowle in that unique aspect of Dark Magic."

"You may not be familiar with that Dark Magic, but we know it very well, or rather, the Malfoy family knows it very well."

"You all know how my grandfather died, right?" Draco sighed.

"Dragon Pox!"

"Could it be that—" Ron and Harry said separately.

"That's the one."

"My grandfather also died from Rowle's curse."

"In the time of Septimus Malfoy, my grandfather's father, he used the Minister for Magic as his puppet."

"People consider it the most glorious era for the Malfoy."

"However, in our own view, the first half of my grandfather's life was the most glorious era for Malfoy."

"At that time, Malfoy was both influenced by Septimius Malfoy and relied on Voldemort."

"In the era when Malfoy was more powerful than ever before, we reached out to Azkaban."

"At this time, my grandfather was cursed by Rowle. Although Voldemort killed Rowle, who had cast the curse, and used various rituals to save his life, he eventually died of Dragon Pox in his later years."

"At my engagement party, fueled by alcohol and thanks to Dumbledore's name, I learned the true principles of that magic from a man named Rowle."

"It is a very peculiar kind of magic, without a specific framework. It is more like an amplifier, amplifying the power of the caster's curses, spells, and even Dark Magic."

"It's called Tartarus, the name of the prison Zeus used to imprison the Titan in Ancient Greece mythology."

"Its creator was Damocles Rowle, who borrowed the concept of Azkaban as a wizarding prison, and added the resentment of those who died unjustly, to build an illusory 'prison' within the body, as an amplifier of negative magic."

"And just recently, the source of Tartarus that the Rowle had been sensing disappeared."

"This seems impossible to them, because Dementors are indestructible, and Azkaban is still considered a wizarding prison by modern wizards." Draco frowned.
