Trapped in This Game With You

They don't remember how they got here and they certainly don't know how to leave. Harry, Ron and Hermione are stuck in a strange game-like facsimile of their time in Hogwarts, but weren't they meant to be stopping Voldermort? This is a game story, but not a 'gamer' story. This isn't a crack or a parody. The game won't be cheated or tricked, you have to beat it by its own rules.
