Backstory

(Student) Nobody ever said it would be easy to be a Slytherin starting as a fifth year. Well, not even technically "starting" in Hogwarts. I somehow woke up here in this "Wizarding World" One minute I was walking through the Metro Station in Los Angeles and with one turn, I found myself on a much cleaner platform with bricks instead of stone and a bright red train instead of a dirty silver tram. Plus everyone had a British accent. It was weird. When trying to find it this was some sort of elaborate Hollywood set, I bumped into some students, and it seemed like they knew me. They said they knew me since my first year at "Hogwarts". That's the name of the school the bright red train goes to. Of course, I want to be extremely careful but the more they talked about this school of magic, the more I wanted to see it for myself.
The only thing is I can't let anyone know I'm not from their world or else they would surely find a way to send me back. AND I have to let them think that I'm the Arely they knew from "before". I wonder what happened to the Wizarding World version of me? Either, I have a feeling whatever I'm about to go through will be completely extraordinary; I just have to find a way to catch up with 5 years worth of magical learning as well as keeping where I am actually from a complete secret. No pressure.
