In the Fourth World storyline of DC superhero comics, Urgrund was an ancient planet whose breakup created two planets: the "majestic, sun-soaked" New Genesis, inhabited by the New Gods and ruled by the Highfather, and Apokolips with its "mammoth fire pits and machinery", ruled by the evil Darkseid and inhabited by his minions and the downtrodden population beneath them. Its name, Urgrund, is German for 'original ground'.
