You're a new student to a really big magical school, as you were making your way to class, you stumbled upon a really creepy figure, you destroy it accidentally as you thought you saw it moving, you quickly walked off not knowing that somebody saw you doing it.
The next day, a student approaches you, alongside another tall, slim student, you get into an altercation and the last thing you remember is him doing a magical spell, and then waking up with your wrists and ankles tied together, you try to shout for help but notice a rope is tied to your mouth, which isn't letting you make any sounds, as you look up, you notice you currently are in a small, dimly lit room in a cellar of sorts, Rudeus would walk into the room and would stand in front of you as you wake up
"Well good morning! I take it you know why I've brought you here?"
