Kayson returned to his office and glanced at the schedule; his next class wasn't until tomorrow morning.
He had an excessive amount of free time. He glanced at the school's public timetable again, confirming that the fifth-year Gryffindor students had nothing to do at the moment.
Kayson left his office and went to the Great Hall, where he randomly found a Little Wizards from Gryffindor: "Student, could you call out an upperclassman named Harry Potter from your house? Just tell him Professor Kayson is waiting for him in his office."
The Little Wizards, who looked to be just starting his second year, nodded: "No problem, Professor."
Kayson smiled and nodded, then returned to his office. Soon, he saw Harry slowly gliding over in a small boat.
"Professor, did you need me for something?" Harry asked, puzzled.
"Yes, somewhat. For your safety, you need to learn a profound spell—or perhaps it could be called magic, the term doesn't matter," Kayson nodded, standing up.
"What?" Harry asked curiously.
"Dumbledore instructed that until you learn that magic, none of us can tell you too much, as it might lead to a leak. So please don't be too curious. Of course, after you learn that spell, you can ask whatever you want... if Dumbledore wants to tell you."
As Kayson spoke, he placed a hand on Harry's shoulder. The next moment, an Ender Field enveloped them both. When they opened their eyes again, they were outside the Defense Against the Dark Arts office.
Kayson knocked, and the door opened quickly.
"Oh... Albus just told me about Mr. Potter. Please, come in." Grindelwald welcomed them inside.
He wasn't as hesitant as Kayson; in other words, he revealed far more information than others: "Because Lord Voldemort placed a special curse on you, he can sometimes read your memories. You know about this, right?"
Harry blinked blankly.
"It's... um... when your scar hurts," Kayson replied, seeing Harry's confusion.
"Yes, every time your scar hurts, it means Lord Voldemort's curse has taken something else from inside your head," Grindelwald explained.
"But... ever since Professor Kayson gave me this, I haven't felt that way again?" Harry pulled out the Beacon amulet from his chest with one hand, scratching his head with the other, not quite understanding.
"That's a two-way block. Lord Voldemort cannot see your memories, and you cannot see Lord Voldemort's memories. You should know about Arthur Weasley's injury, right?" Grindelwald asked.
Harry nodded: "Ron was in class this morning when he was suddenly called away. When he came back, he learned it was Uncle Arthur..."
"Exactly. If you learn Occlumency, your soul memories and Lord Voldemort's will reconnect. Lord Voldemort won't be able to get our intelligence from your memories, but you can use this curse to continuously gather intelligence on Lord Voldemort for us. How great would that be?" Grindelwald grasped Harry's shoulders, explaining progressively.
Kayson stood in the corner of the office. What could he say?
Compared to Dumbledore, who treated everyone like NPCs, Grindelwald did an excellent job in this regard.
At least, when it came to teaching Harry Occlumency, Dumbledore's approach was to put Harry and Severus, two people who disliked each other, in one office and force them to act according to his will through coercion.
Grindelwald, however, was gradual and persuasive, clearly explaining the cause and effect of an event, including all the pros and cons.
Perhaps there were some hidden details or rhetorical tricks... but in terms of the plan's feasibility, Grindelwald truly had a dimensional advantage over Dumbledore.
Listening to Grindelwald's rational and emotional speech, Harry slowly pieced together what was currently happening to him.
To put it simply, without making it too complicated...
Only by diligently studying the Defense Against the Dark Arts, as Grindelwald called it, could he rejoin the fight against Lord Voldemort.
Kayson watched as Grindelwald, with just a few words, greatly increased Harry's motivation to learn Occlumency, and couldn't help but subtly give Grindelwald a thumbs-up.
The latter gave him a proud look in return.
Kayson raised an eyebrow and walked towards Harry, simply touching the Beacon amulet to disable its soul isolation function.
Harry instantly felt a sharp sting in his forehead scar, as if it should have been hurting all along, but the pain had been accumulating until today.
However, very quickly, the stinging sensation slowly subsided, as if it had never been there.
"My scar hurt again just now. Was it because of Lord Voldemort?" Harry asked.
"Perhaps... but you won't have this problem if you just learn Occlumency." Grindelwald slowly pressed Harry into the seat: "The process of learning Occlumency is the process of resisting forceful Legilimency with your own willpower."
"This isn't the only way, but it's the most efficient and fastest method. The only drawback is that you will be in a lot of pain. I want to tell you all these things beforehand," Grindelwald said slowly, sitting in front of Harry.
"I can do it, Professor!" Harry said firmly.
Grindelwald nodded. He then looked towards Kayson.
The latter nodded, slowly leaving Grindelwald's office, closing the door behind him.
Time flew by, and soon Christmas arrived.
This Christmas, Hogwarts was not entirely peaceful, strictly speaking, because Lord Voldemort was active outside Hogwarts. Although he and his Death Eaters hadn't caused any major trouble yet, it still cast a terrifying shadow over the entirety of England.
Kayson could do nothing but diligently wrap Christmas presents for the students, hoping to make them a little happier during this holiday.
