I Am Tierra

"Hmph." Sirius snorted coldly, forcefully shook off Tierra's grip on his wand, and sat back down in a huff.

"Very well, then you can continue your conversation." The two Tierras bowed slightly and smiled at the same time. "But I still hope Mr. Black will not remain in the school for too long."

"This is, after all, a school under closed management," Tierra said. "Unless there are special circumstances, such as a student or their guardian being injured, ill, deceased, or involved in a major criminal or disciplinary incident, parents and guardians are not permitted to visit students."

"Hmph." Sirius snorted again and did not respond to Tierra.

"Wait, Tierra!" Harry suddenly called out to Tierra at that moment.

"What is it, Harry?" One of the Tierras turned and asked, while the other drifted away.

"Well, Tierra, I... I don't want to learn Occlumency from Snape," Harry said bluntly. "Can't I learn Occlumency from you?"

"You can't, Harry," Tierra refused directly.

"But, but..." Harry seemed to want to argue further.

"I've already told you the reason, Harry." Tierra's tone became somewhat stern. "My Occlumency came from a unique potion and from the mental contamination I often suffered from Voldemort in the past."

"And that unique potion can only construct a mental barrier outside your mind," Tierra said. "That mental barrier may very well separate your soul from Voldemort's—"

"In short, my ability to teach Occlumency is not as good as Professor Snape's. After all, he learned Occlumency from scratch, step by step, through his own efforts." Tierra spoke earnestly. "So I believe Professor Snape is more suitable to teach you."

"Heh—" Sirius let out a strange laugh. "I think it's because you don't even know it yourself, do you?"

"Provocation has no effect on me, Mr. Black," Tierra said gently.
