Imagine the universe being a man. Earth would be at his feet; Heaven would be at his feet; and Hell...well, Hell would be somewhere around the viciniy of his rear end. Hell was a very large place. It had large palaces, massive castles and enormous prisons. Hell was made up of four main wards: the naughty step ward; the murderer ward; the mass murderer ward; and the new arrivals ward.
He had a good businness going on. People came in and he showed them where to go. He met lots of interesting people like Genghis Khan and Hitler and told them where their wards were. However, because the world was becoming more and more corrupted, there were more and more people to direct. And because of that - Death kept making more and more mistakes.
