An infinite multiverse with cube space-time continua.

This is a connected layer of Multiverse 2, numbered 2A and 2-1.

Similar to it's parent multiverse, the cubes rotationally show civilized planets.

The cube universes can also rotationally show civilized regions of space at the same time.

If there's no civilizations present at all, not even one, then a cube will appear to be pitch black.
