Inter-Dimensional Limbo

In the Earth-One universe, exists an Inter-Dimensional Limbo or an other dimension.

Within this pocket-dimension, are brooding, amphibious creatures that float around the pocket-dimension on huge eggs. We also know that the Red Jar of Calythos was found, sometime in the 30th century floating around inside the pocket-dimension.

Beyond that, not much is known about this Inter-Dimensional Limbo.
