Hm, well, that's what I always kinda imagined the courtyard before for, with the fountains and trees and what not.
But if it's a more natural place you're looking for, the Academy is practically in the middle of nowhere and I imagine there's a lot of nature surrounding it. Maybe some kind of recreational area could be made... With a small side of a lake.
It wouldn't be able to be too big though and would have to be open so no one could really hide out there. And there'd have to be a huge fence. The Headmaster's shield would also have to reach out there.
I don't know, I could go either way on this. It could happen, the Headmaster is a damn, rich bastard. o 3o
What do other peoples think?
