Defense Against the Dark Arts professors at Hogwarts have worse job security than the cast of Game of Thrones. If you take up the post, there’s a very real chance you’ll wind up dead or locked in a trunk or carried away by a herd of centaurs. There’s also a slim (we’re talking minuscule) chance you’ll be completely fine.
So, would you stand the test of time? Or would you wind up being the yearly Hogwarts sacrifice to the wizard gods?
