HP in the name of Slytherin

Grindelwald, a genius dark wizard, was born with the gift of prophecy and was good at playing with people's hearts. He independently developed many novel and powerful magics, and once almost burned down Paris.

Severus was also a talented young wizard. Not only was he extremely talented in potions, but his sensitivity to spells was also different from ordinary people. He had learned about the structure of magic through his own exploration. After Catherine's guidance and Haier's guidance, he Bo's sparring partner, he now masters more magic than some adult wizards.

He only lacked the accumulation of time. This child's body could not carry more magic power. This turned out to be his only shortcoming.

The more he got to know Severus, the more Grindelwald was amazed. He took out many of the magics he had designed in Nurmengard. He originally wanted to test Severus's depth and limits, but he only With just a brief introduction, Severus could help him break it down clearly and even give him constructive suggestions.

Couldn't Grindelwald see that Severus was trying his best to shine like the sun, attracting his attention and keeping him occupied?

Of course you can see it.

Including Severus later deliberately showing his understanding of the theory of curses. This is a boring and advanced subject that many wizards have no interest in or ability to study. He just understands it and likes it.

Couldn't Grindelwald see that after Severus got him interested in this way, he used more magic, seemingly testing each other's spell limits, but he was actually openly learning his magic?

Of course you can see it.

The two of them tested each other and never tired of it. Grindelwald stayed at Hogwarts for a few days and really didn't make any big news. He spent the whole day either in class or studying magic with Severus, and he had a lot of fun.

Dumbledore observed several times through special means and found that Grindelwald was really very honest, but the way he looked at Severus gradually became very... well... fanatical.

Like a research maniac, find an excellent research material...

God knows how surprised Dumbledore was when he saw Grindelwald writing and drawing at night, thinking that he was doing some dangerous research, but when he took a closer look, it turned out to be a "lesson plan" for Severus.

This time, the keen Grindelwald caught the flaw.

"Al," he called him softly.

It would be too deliberate to avoid him at this time. Perhaps the suspicious Grindelwald would feel that he was spying on him and did not trust him... although this was true.

"Gellert." He appeared in the phoenix's fire and looked down at Grindelwald who had returned to his original form at the table.

Different from the past few days, Grindelwald today even has his beard beautifully groomed. When writing at the table, he looks like a quiet and elegant old gentleman.

Unfortunately, this was not the feeling when I spoke: "I remember this is the women's dormitory?"

Dumbledore: "..."

Grindelwald shrugged lazily and said with a smile, "Just a joke."

Dumbledore wanted to roll his eyes at him.

However, Grindelwald himself joked about it, which showed that he didn't care about being seen by him.

Grindelwald even generously handed the notebook to Dumbledore.

"Hogwarts is such a nice place." He said with emotion.

Dumbledore was not polite to him. He took Grindelwald's notebook and flipped through the pages.

Starting from the first page, it is Grindelwald's summary and experience of using magic over the years.

Then he started to talk about some of his magic, from spells, to effects, to basic principles, shortcomings and modification ideas.

Finally, it was what Dumbledore had just seen, some ramblings mixed with Grindelwald's personal characteristics, writing some magic learning plans and possible problems he might face, and the tone seemed to be directed at someone...

After reading this entire book, Dumbledore suddenly felt sad.

Grindelwald put his head on one hand and said with a smile: "We are all old, Al."

In the past, Grindelwald would never have thought about how he would grow old, let alone write down his magic and pass it on... even if it was just passed on to someone.

Like the old wizard in ancient times, he held on to his magic tightly and waited for thousands of years to find a suitable apprentice and teach him his magic.

In such a story, Grindelwald never thought that he would become the protagonist.

"Quidditch makes my heart feel a little uncomfortable. Sometimes I feel noisy when the children laugh when they are happy," he murmured. "I used to read day and night, but now my eyes feel a little sore." If you don’t sleep, you will feel sleepy the next day.”

"You just... haven't recovered yet." Dumbledore also said softly.

It's rare for them to be so harmonious.

"No one is immortal, and death is just another great adventure."

Grindelwald smiled and said: "At least I have found a suitable apprentice now. He is really an interesting kid."

"Severus, you are indeed excellent."

"Do you think that after he learns all my magic, he will still be able to work as Miss Slytherin's subordinate?" Grindelwald suddenly said harshly, "It's not like a smart person like him would be willing to be someone else's subordinate."

"He and Catherine..." Dumbledore said, seeing Grindelwald looking quietly into his eyes.

Those eyes are as blue and quiet as the black lake at night.

Severus and Catherine.

Him and Grindelwald.

Dumbledore suddenly smiled and said, "They are different."

As if some kind of magic had been broken, Dumbledore broke away from his strange emotions and stroked the wand as if carelessly.

"You were using the magic field just now." He said as if he was questioning or stating.

Grindelwald lazily raised his hands in surrender, "I'm just curious. This is not a magic field. I lack a lot of key information."

Dumbledore still had the same expression, but Grindelwald, who was familiar with him, knew that his body had tensed up and was ready to teach him some lessons at any time.

Yes, he was different from Albus, from Severus and Catherine.

…But it’s not that different.

They were once so happy.

Grindelwald slowly put down his hands of improper surrender, but said more sincerely: "I'm sorry, Al, I'm really just curious, you know."

Dumbledore stared at him, and after a while he seemed to sigh, "I know."

Just as the smile appeared on Grindelwald's face, he heard Dumbledore say again: "But the human heart cannot stand the test, and you know that, right, Gellert."

Grindelwald looked at Dumbledore blankly.

The two were in some kind of stalemate.

Dumbledore quietly looked at Grindelwald, who was meticulously dressed and had short hair and beard. He looked energetic and seemed to be in his fifties or sixties.

Grindelwald also looked at the old Dumbledore, who had a long beard but was playfully tied with a small bell. He looked very old.

In fact, they are all old, ninety years old. Some Muggles can live two lifetimes.

Grindelwald looks younger, but his heart has been barren for many years.

Dumbledore looks old, but he...he always seems to be forever young, in mind and soul, always shining, and never falling.

Al, once like light, like an angel, Grindelwald was fascinated and longed for him.

"It was me..." Grindelwald felt his throat was dry, and finally sighed and smiled bitterly, "It was me who was wrong, Al."

Now and still.

Grindelwald whispered: "I'm sorry."
