Press F5 to Fast-Flamel

Harry Potter is yoinked from his home world, and ends up in a video game by accident. BvB duelists, armed cat rebels, fatal bouts of spontaneous nudity, and gaudy pieces of overly-talkative, homicidal, very-nearly-family heirlooms; there's a long list of obstacles he'll need to overcome to make his way home - or at least make it to the end of the next level.
