Overworld

The Overworld is the term for the real-world. Mostly used for parallels with time, as the Outlands don't have a formal time system. The Overworld is unknown to the entities of the Outlands, or at least their knowledge of it has not been observed. The Regions of the Outlands seem similar to those of the Overworld, but more generally than specifically, like the regions of the Metropolis or the the behavior of the Hunter.

Other inspirations for the Outlands come from common Overworld mythology, such as The Witch.
