B-Continuum
From Multiverses
The B-Continuum is often thought of as the 'standard space' in Obeidon, containing all the known universes.
Universes
There are many others.
Crossverse
The B-Continuum also contains the Crossverse, which links almost all universes and allows advanced races to travel from one universe to another. Dimensional Rifts are shortcuts through this space, produced around the universes.
Hyperspaces
All universes in the B-Continuum other than Vesania and the Crossverse have a corresponding Hyperspace, accessible using a Hyperdrive.
