An old building, part cathedral, part tower cupola, part central European mishmash, set in the middle of a run-down urban area is the perfect setting for a spooky academy. Or maybe it's the residence of an old, old man. A hermit, living off his supernaturally-tainted old-world money. A man like this gentleman, perhaps.
It's a place only the very brave go to trick-or-treat.
