Harry Potter and the Great Old Ones

Chapter 629 Special Guest
“Oh, I... I just escaped... I mean, I just left McLean,” Hermione said somewhat flusteredly. “I mean, under the parasitic vine.”

She added. Harry still looked puzzled.

“It was the right decision to come with him!” Harry said, half-jokingly and half-teasingly.

“He was the first one to invite me!” Hermione said, sounding both angry and annoyed. “I initially thought Tyella wouldn’t be attending the ball!”

"So I just picked one randomly, because I was busy with the math problems Tierra gave me and didn't want to spend time choosing a dance partner, so..." Hermione scratched her head in annoyance, but she didn't dare to use too much force, because before the ball started, she had used the hair-transforming charm that Professor McGonagall had taught her a while ago and a lot of conditioning agent on her broom-like hair, and she was afraid that she would cause her hair to explode if she moved too much.

"Who told you not to consider me?" Harry said gloatingly.

"Seriously Harry, I was wrong. Well, to be honest, I always thought of you as my best friend, my confidante, my sister. I almost forgot you're a guy too!"

—And my son.

Hermione thought to herself, then pulled Harry towards the edge of the crowd.
The three of them walked from one side of the room to the other, and it was too late when they realized that Professor Trelawney was standing there alone.

"Hello," Luna greeted the professor politely.

“Good evening, my dear,” Professor Trelawney said, focusing somewhat awkwardly on Luna.

Harry could smell the warm sherry from her.

“I haven’t seen you in class for a month or two—” Professor Trelawney said.

“Oh no, I just transferred to Mr. Tierra’s class,” Luna said.

“Oh, of course,” Professor Trelawney replied, both angry and frustrated.

During the Second Hogwarts Teacher Education and Teaching Seminar, Tierra introduced the concept of parallel experimental classes—

In other words, for certain courses, Tiera would offer an identical course but with different teaching methods, such as methods modified based on the situation in the magical world. Through comparative experiments, they would uncover the flaws in the original magical world's teaching methods and identify strategies for improvement.

And some courses.
Tierra refers to Trelawney's divination class.

Whether it was Salazar Slytherin, the representative of the board of directors, Dumbledore, the headmaster, the teacher representative, or Thierra, the student representative and investigator, they all agreed that Trelawney's divination class was absolutely terrible.

At the same time, they all agreed that Hogwarts didn't lack the money to support another idle person.

Therefore, Tierra proposed the concept of "parallel experimental classes" to undermine Professor Trelawney's courses in a way that would not hurt Professor Trelawney's pride.

For this reason, Tierra even gave Professor Trelawney a raise, euphemistically calling it "a subsidy she deserves for participating in the experiment."

Of course, Tiera wasn't very good at teaching divination, since, to some extent, Tiera's prophetic abilities relied entirely on "talent" and a kind of divine ability a master strategist possessed.

Therefore, the full title of Tierra's divination course should be "Elementary Training in the Abilities of Foresight: Training in Observation." Everything unsuitable for other courses is placed here—

For example, basic logical thinking skills, reasoning skills, observation skills, analytical skills, and so on.
Tierra even went so far as to cross the Pacific Ocean and spend several days getting his hands on the authentic training materials from the CIA headquarters in the United States, making some edits and adding them to the lesson plan.

The response seems to be quite positive.

Even Parvati, the Indian twins who were originally the most devoted to Trelawney, and Ron's girlfriend Lavender, abandoned Professor Trelawney and switched to Thiera's class.

However, Tyella didn't care about any of that, nor did he care how many people chose his course or how many left Trelawney's. He had set himself a twenty-year timeframe, and he was determined to completely change the corrupt state of the wizarding world within those twenty years.

He still has plenty of time and experience.

But he always had to pretend to be extremely busy and overwhelmed, otherwise how could Voldemort take the bait?
Aside from reorganizing the entire Ministry of Magic, Tyrell really didn't have much else to do. After all, she had already established her power and was just waiting for Voldemort to take the bait, then Tyrell could catch him like a turtle in a jar.

This is why Tiera encouraged Horace Slughorn to send out invitations widely.

“Professor Slughorn.” Tiera, who hadn’t invited any dance partners, calmly approached Horace Slughorn after finishing a glass of shimmering gold champagne, patted him on the shoulder, and whispered in his ear:
“Professor Slughorn, it’s time to invite our special guest to the stage.”

“Oh, yes, yes, yes,” Horace Slughorn said, beaming. He wasn’t too concerned about Harry’s escape; as far as he was concerned, the ball was still a long way off, and he would find a way to bring Harry into his circle of good students.

Harry and Luna arrived here almost on cue, hoping to avoid being dragged around socializing by Horace Slughorn.

So while Harry, Luna, and Hermione were slightly tipsy and still grumbling about Professor Trelawney's dwindling student numbers, Horace Slughorn, holding a wine glass, stood on a platform significantly higher than the ground, along with one of the fifty-odd Tyrells who had come to the Christmas ball and a tall, thin old man with a long beard and sunglasses.

"Ahem, ahem," Horace, the banquet organizer, coughed a few times after everyone had arrived, standing on the podium, and then—

"Ding--"

He tapped the empty wine glass in his hand with his fork.

"Ladies and gentlemen, good evening."

Once everyone's attention had turned to him, Horace Slughorn smiled and said...

"Welcome everyone to the Christmas Ball hosted by the Slughorn Club. You are all outstanding students at Hogwarts, and you will be the pillars of the British Magic Association and even the future wizarding world. You are bright new stars rising in the wizarding world."

"I hope that tonight, everyone can not only enjoy delicious food, sweet wine, and beautiful music, but also that as the dances come to an end, our friendships will be extended."

"Before everyone gets too caught up in the fine wine, delicious food, and warm friendship, I'd like to introduce a special guest. Please welcome him—"

"Salazar Slytherin!"
