HP: Employee Zero of the Ministry of Magic

Hogwarts, History of Magic. "Today, we are going to talk about a legendary figure - Tyr." The teacher pushed up his glasses with a solemn expression, "He once helped us defeat the most terrifying dark wizard in history. Without him, there would be no magical world today." The classroom was quiet for a second, and then exploded. "Teacher! I heard that Tier is your friend?" The teacher was silent for a moment, and the corners of his mouth raised slightly: "We try not to discuss extracurricular content... But, um, yes. He is my friend." "Wow——" "Did he really travel from ancient times?" "... Yes. As written in the book, he came from the early days of Hogwarts and was the first student of Gryffindor House." "He's still employee zero of the Ministry of Magic!" "Friends of magical creatures! Liberator of elves!" "He single-handedly defeated an entire army of dark wizards!" "I heard that he doesn't rely on translation spells to chat with legendary magical creatures!" "He is the director of the 'Return the Crucible to the Cake' association! A crucible cake crazier! The world's crucible cake eating time trial record holder!" The teacher knocked on the podium lightly and said with a smile: "He is also the most loyal partner I have ever seen." Breaking through the fog of thousands of years, a song of love and courage, a legend beyond magic. He is not a name in history—he is the maker of history. He doesn't like to be in the limelight, but the limelight cannot escape him. Now, witness – real magic!
