An Undefined Multiverse where there is not one, but three central sources of gravity. The inhabitants are only capable of moving about in two different gravity sources exclusively.

An Undefined Multiverse is the term used for Multiverses that have no real defining traits, ones that could easily be fitted into another multiverse, without repercussion or much difference or alteration.

Since they have no real extravagant defining inhabitants, locations, or functions to their realities, they are not given any form of classification.

Sometimes, if something happens that is particularly extraordinary, then an Undefined Multiverse can be defined by it, and then given classification.
