Arthur is all alone now, he killed the world. He had it all, but that wasn't enough, so he went and ruined everything. God left in a hurry when the atomic bombs went off, and forgot to take poor Arthur with him. Now he lives in a sealed bunker under an irradiated wasteland once known as Florida, and watches the worlds he missed, the possibilities he prevented, in his ingenious, insidious creation: The Alternate Reality Generator. He only had one friend left in the world, a floppy eared Labrador, but he's dead now, too. That's probably Arthur's fault as well. Now all he has is time and regret...and a machine that lets him live all kinds of lives, in another dimension...
