The so-called Fourth World was another dimension, although some sources refered to it as a "closed galaxy." The dominant alien species of the universe was the New Gods, which were natives of the planets New Genesis and Apokolips.
In this universe, there once was a planet called Urgrund, and it was ruled by a race now known as the Old Gods. Eventually the planet split into, and two planets formed into what would become known as New Genesis and Apokolips.
