Darkness, mystery, legend - these are the whispers that echo through time regarding Atlantis. A kingdom long since forgotten to surface dwellers, it is here that a hidden empire teeters on the brink of war. When a military submarine traversing this remote domain is attacked, Cyborg plunges to the murky depths to investigate the wreckage. What he encounters is a threat powerful enough to rally together the newly formed Justice League. Meanwhile, thousands of feet above the ocean floor wanders the lone drifter Arthur Curry, a man with strange powers who may be the last chance to bridge the ancient Atlantean world and our own.
