New Genesis
The residents of New Genesis call themselves the Forever People. They belong to the race Homo Immortalis, also known as Eternals.
New Genesis and Apokalips exist in an adjacency to Yggdrasil but are not strictly a part of the realms of the Demiurge. The realm was created by Celestial spatial engineering as a testing environment for a control group of Homo Immortalis.
It is a binary planetary system that consists of two worlds-- New Genesis and a sister realm of Apokalips. New Genesis is a lush and verdant planetary body with substantial mineral and vegetative resources. There is some social friction between the two primary social castes on that planet; the Forever People dwell among the clouds on flying cities, while the 'bugs' live on the surface and provide much of the labor and provender that the residents of the flying cities require. Many of the bugs are descended from the very few Deviants who survived a civil war with the young legions of the New Gods.
New Genesis and Apokalips have a uniquely polar arrangement with one another, creating a position for not one, but two Primarchs. Of New Genesis, the Primarch is the mighty Highfather who is the leader of the 'Forever People'. On Apokalips, the mighty Darkseid wields an inverse force called the Omega Force that is the destructive antithesis of the Power Cosmic.
Much akin to Asgard, New Genesis exists with a relationship to temporal space. Due to immense space-time curvature around New Genesis and Apokalips, shearing forces prevent traditional space travel via Hyperspace. Transport requires a specialized mode of interdimensional transport called a Boomtube to prevent being shredded by gravimetric shearing forces.
New Genesis existed apart from the other realms of the Demiurge for many millennia, developing a rich and sophisticated society that effortlessly integrated science and cosmic energy. When the events of Ragnarok unfolded in 15,000 BCE, the Eternals were trapped in New Genesis by the machinations of Darkseid and Oa to ensure they could not aid the Celestial war host.
