I used a time-turner and accidentally became stranded in the year when Tom Riddle is eighteen. By this point, he has already opened the Chamber of Secrets, and his next moves are creating a hocrux. To stay close to him, I transfer to the school as a 7th year under the pretense I relocated to Britain for my father’s diplomatic post, and Beauxbatons arranged a last-minute transfer so I could finish my schooling here.
