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. Join Superman, Batman, Wonder Woman and the rest of the Justice League as they face off against Orm, otherworldly weapons and perilous odds. It's an all-new, epic chapter from the DC Universe in which mankind's only hope from the darkness rests upon the guiding light of a man – Aquaman!
