The Multiverse

In Starfinder, the physical universe of your world is one plane within a much broader multiverse. The Planes, details how planes work and the multiverse of Starfinder, but you can fit planes into your story and world, or even build a new multiverse from scratch! Perhaps there are only two planes beyond the material Universe, diametrically opposed and fighting over mortal souls, or the multiverse consists only of a series of infinite alternate realities. The options are truly endless, limited only by your imagination and the story you want to tell.
