The Dark Realm

The Dark Realm, sometimes called the Dark Dimension, is a world of nothingness. It is used by powerful wizards, supers, and celestial beings as an eternal prison for their adversaries.

History
The Maker was trapped in the Dark Realm by Nick. Both the Caped Combatant and the Creator were sucked into the Dark Realm. The Maker was brought back by a few of his followers.
