Material Plane
The Material Plane is the Inner Sphere reality in which the planet of Golarion finds itself, along with its sun and its 10 sister planets. It is an unending universe occasionally harboring life on terrestrial planets or other less-stable celestial bodies. Most mortals live out their lives on this plane.
The immense void between the stars harbors strange life. This region is known as the Dark Tapestry, and is home to creatures stranger than any found in the Outer Rifts. It is here that is said that the Outer Gods and Great Old Ones are said to dwell.
Creation
Genies and elementals state and believe that the Elemental Planes existed before the birth of the Material Plane. Eventually, the Elemental Planes mixed with the Positive Energy Plane, Creation's Forge, and the latter's life-giving energies helped create the Material Plane. Many scholars believe there is some element of truth within this myth regarding the real historical facts.Metaphysics
The Material Plane is metaphysically coterminous with the First World and Shadow Plane, existing in slightly unaligned dimensions of the same cosmological space with the Ethereal Plane between them as a bordering transitive plane. The First World is pulled away from the anchoring Material Plane by its relationship to the Positive Energy Plane, while the Shadow Realm is pulled away by the Negative Energy Plane.The Material Universe
The Material Plane is practically infinite in scale, with galaxies separated by vast voids, each galaxy containing countless stars, many stars anchoring systems of other bodies, and innumerable other phenomena in between. Its diversity, which blends concepts and creations from all other planes across its countless worlds, results in many metaphysical scholars placing the Material Plane at the center of multiversal modelsGolarian's Solar System
Even though Golarion has the most diverse lifeforms and cultures of the planets orbiting its sun, it is not alone in the solar system. Other planets include Castrovel, Akiton, Liavara, and Bretheda. Magical gates created long ago by lost civilizations are said to connect Golarion to its sister planets.Dark Tapestry
