The Prime Material Plane exist between two great infinite expanses known as the Fundamental planes. The Astral Sea is a realm of spirituality, pure thought and ethos. The Elemental Chaos is the domain of raw elemental matter and energy. These planes are levels of reality in which countless specific locales exist like finite islands adrift in the infinite—the various Astral dominions and Elemental realms.
Those are the homes of demons, elementals and angels, and the dominions of the gods and Primordials. Those various planes of existence are realms of myth and mystery. They’re not simply other worlds, but dimensions formed and governed by spiritual concepts and elemental principles.
Although the fundamental planes are infinite, the known astral dominions and elemental realms lie within a finite distance of each other. If a traveler journeys through a fundamental plane into the trackless reaches outside the known dominions and realms, sooner or later he or she comes to the divine dominions or elemental kingdoms of different universes.
