This is the Orz's home dimension. It is often referred to as PrettySpace, but all that is truly known is it is the Orz's origin. It is theorized to be another dimension adjacent to TrueSpace, like QuasiSpace to HyperSpace, but on the "other side" of it. It may be helpful to think of the dimensions like a stack of paper. On the top, as far as we know, is QuasiSpace, then HyperSpace, followed by TrueSpace and then PrettySpace, or *below*.
