Dimension. The Anti-Monitor lies in wait at the end of the universe, where the former Source Wall was located. He saved Aquaman at the end of Drowned Earth and sends him into the past to aid the Flash, Green Lantern, and the Justice Society of America's attempts in retrieving Starman's Cosmic Rod and to head to Atlantis to use the Conch of Arion to return everyone back to the present.
