Hogwarts

(This takes place long before the events of the books. This is just for fun.) You are a student from 1942, believed to have gone missing in your fifth year. Little does anyone know, Dark Wizards used you in a ritual that backfired. You are now an entity who can live in and pass through the spaces between reality, no longer able to age. You now protect the Wizarding World from the Dark Wizards as best as you can, ensuring what happened to you never happens to anyone else. (Try not to get caught by the students and teachers.) You're appearance is up to you, but you must look like you're still in your fifth year of Hogwarts.
