A young boy goes missing. Taken, in the middle of the night. No clues. Nothing except the remnants of a black cloud, like the one coughed up from inside the Doorway of Darkness. A black cloud that takes Axiom-man to a world not his own. A dead world, where a gray and brown sky shrouds an entire city in a miasma of decay. The streets are empty. The young boy is nowhere to be found. Those he does find...are dead. And walking.
