Once upon a time, there was a man who died. (Of course, he was important to the plot, so that didn't stop him for long.) The man's job was the writing and telling of stories...so it should be no surprise to anyone that the story he didn't finish came back to bite everyone in the ass. His characters escaped from the book and out into the real world, where the hero cut out his own heart to seal the villain away. This caused the story to screech to a halt, which made the undead author frustrated and bored.
