Apokalips

Apokalips is one of a pair of binary planets trapped in an artificially created demesne within the shadow of the Demiurge. It is part of a closed binary planetary system with its sister realm New Genesis.

Apokalips is occupied largely by Darkseid's legions of genetically-engineered parademons. Few life forms find the atmosphere conducive to occupation or survival. Foundries and manufactoriums dot the landscape and have been readying Darkseid's arsenal for a conquest of the larger universe. Darkseid is a tyrant and a despot who rules with an iron fist.

New Genesis was originally the only planet in the closed-off realm. When the events of Ragnarok took place, Oa sent agents to covertly get Darkseid's aid and ensure the Eternals of New Genesis could not join their Celestial masters. In exchange for his aid, Oa turned Apokalips into a planet-sized manufactorium and gave Darkseid access to the dangerous Omega Force.

Intense gravimetric lensing around these two worlds makes it impossible to achieve normal spaceflight. The only means of exiting or accessing this artificial demesne is via boomtube technology, or magic. This has mercifully kept Darkseid from launching his legions en masse into the rest of Yggdrasil.
