I, Squib, the Most Powerful Professor of Magical Creatures

"Karsus, I invited you to teach at Hogwarts. This is the invitation letter and contract!" Dumbledore handed over two envelopes very simply. "What?" Karsus, who had always been expressionless, finally turned his head and looked over. "I think you heard me clearly!" A smile appeared in Dumbledore's eyes. "I, Karsus, am a 17-year-old underage, a Hogwarts dropout, a squib, and a trainee in Azkaban... You invite me to be a teacher at Hogwarts??? Have you reached this level of age? Didn't you say that wizards don't have Alzheimer's disease?" Karsus looked in disbelief. This was the most exaggerated thing he had ever heard in his life. Hogwarts retiree. Squib. Azkaban prisoner. Recognized by the Ministry of Magic as the biggest terrorist. Only 17 years old. These stacks of buffs made Karsus himself feel distressed. How dare Dumbledore? "Yes, you must be the professor of Magical Creatures!" Dumbledore smiled. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
