"Have you ever heard of Arthur C. Clarke's third law of prediction? It states that any sufficiently advanced technology is indistinguishable from magic. Take a smart phone and hand it to an ancient Roman. He'll think it's a magic window into the world of the gods and that the Beyoncé video playing on it is showing him Venus. The broom is magic. The inn is magic. I'm magic. I can feel it, I can manipulate it, but I can't explain it. You've transformed hundreds of times in your life under the belief that it's magic. Why does it matter now that it's not?"
