Ueiqdn

Ueiqdn (oo-'ayk-duhn) is the name of all existence in which all worlds are contained. It is also used in the context of the Omniverse, a hypothetical all-encompassing multiverse from which all other multiverses and universes can be accessed. While continued discoveries of overarching multiverses may indicate that the world hierarchy is in fact infinitely deep with no root, Ueiqdn is still used to describe the space within which that world tree exists.
