After the Crisis on Infinite Earths the Superman and Lois Lane of Earth-2 along with the Superboy of Earth-Prime and Alexander Luthor of Earth-3 went into exile within a pocket dimension. There they lived peacefully until Luthor began to observe that the reality they left behind became more bleak and its heroes began to fail in their duties to uphold virtuous values.
When Lois Lane's heath began to decline due to old age, Superman was adequately distracted for Luthor to initiate a plan to revive the planet formerly known as Earth-2. Working with the Superboy of Earth-Prime, Luthor engineered a series of events including the formation of the Secret Society of Super-Villains, the manipulation of magic and technology and the fomenting of a galactic war all in hopes of creating an Infinite Crisis and a New Earth.
