Harry Potter and the Great Old Ones.

Chapter 728
“If you want to know, you can listen to Professor Trelawney’s divination class.” Tierra did not answer directly. “You will be taught some knowledge about dream divination in your third year.”

“But right now, I don’t think your dreams are related to signals guided by the spiritual dimension.” Tierra smiled slyly, then sniffed the air twice. “I smell dark magic on you.”

"Dark magic?" Brireim stared blankly at Tiera, his eyes filled with a pure innocence untouched by knowledge.

"What...what kind of black magic?" Brireem asked nervously.

“It’s not some kind of dark magic,” Tiera asked with a smile. “Do you want to know? If you do, I can show you.”

“It’s not a bad thing for a young wizard like you to get a head start,” Tierra said after a pause. “Consider it a preview of what you’ll be learning in third or fourth grade.”

"Is it...is it okay?" Brireem found himself feeling nervous, scared, and a little bit excited that he couldn't hide.

“Of course, why not?” Tierra stood up from the table he was leaning against and waved to Blairim, signaling him to follow.

Brireim jumped off his seat and followed Tierra with a trot.

"Remember to put the book back in its place next time," Tiera waved.

The books that Blairim had pulled out flew up from mid-air and "whoosh whoosh whoosh" returned to their original bookshelves.

“Otherwise, Mrs. Pince will be angry,” Tierra added.

"Are you afraid of Mrs. Pince too?" Brireem asked, following behind Tierra with a bewildered look. "It's not fear, it's the respect I, as a student, a teacher, and someone who truly holds power in this school, owe her," Tierra explained calmly. "We should respect school rules, and also respect the rules of society, maintaining the right attitude towards both. This is an essential quality for becoming a good wizard."

"What are you laughing at?" Brireem asked, puzzled.

“It’s nothing, it’s nothing,” Tyella said. “Although I said those words, when I think about it carefully, I’m not a good person myself. In my short six years at Hogwarts, I’ve broken enough school rules and Ministry of Magic laws to send me to Azkaban a hundred times over.”

"Oh, is that so?" Brireim stared at Tiera with his clear, large eyes, somewhat puzzled.

Brireim's simple little mind couldn't understand why someone would call him a "bad thing".

They left the library, went down one flight of stairs, and arrived at the dark magic classroom on the third floor of the school.

This place used to be Moaning Myrtle's bathroom and connected to the secret passage of Slytherin, but it was transformed into a dark magic classroom by Longiersue, who was "resurrected" a year ago.

"Please sit down." Tiera raised her hand, and a stool flew over, appearing under Blairim's bottom, and then carried Blairim to the podium at the front of the classroom.

Tierra's platform also serves as the largest magical experiment table in the entire classroom.

The lab bench was covered with all sorts of experimental equipment, including test tubes, beakers, microscopes, and magical instruments of various shapes and colors. They were all mixed together and looked quite messy.
