Great Beyond

The Great Beyond is a term that encompasses all the planes of existence that make up the known multiverse. These realities beyond our reality are the domains of the gods, and play home to non-godly powers fit for worship, planar dragons, and entirely alien races.

There are nineteen major planes that comprise the Great Beyond, modeled as two spheres: the Inner Sphere and the Outer Sphere. Connecting the two spheres is the Astral Plane. The spaces between the primary nineteen planes contain countless demiplanes. Despite the names implying a spherical layout, the planes exist on dimensions incomprehensible to mortals, thus these terms are used to represent the planes in two or three dimensions.

Inner Sphere
The Inner Sphere is the center of the Great Beyond, sitting at the hub of creation surrounded by the Astral Plane. It is composed of the immensely huge, yet finite layers of the Elemental Planes, which surround the Material and Shadow Planes, which are in turn separated by the Ethereal. At the metaphysical center of these sit the dualistic Positive and Negative Energy Planes.

Astral Plane
The Astral Plane surrounds the Inner Sphere, and fills the space between planes of the Outer Sphere. The Plane of Fire, outermost of the inner planes, is often shown in maps of the multiverse as being a dot or burning sphere floating in the Astral Plane at the center of the Outer Sphere.

Outer Sphere
While the Inner Sphere contains the elemental planes, the Outer Sphere contains nine planes, each with a strong link to a particular philosophy and alignment. These are the dwelling places of Golarion's gods.
 * Axis
 * The Boneyard
 * The Maelstrom

Lower planes

 * Abaddon
 * The Abyss
 * Hell

Upper planes

 * Elysium
 * Heaven
 * Nirvana

Demiplanes and other dimensions
The multiverse is hardly a neatly-organized system, and innumerable planes and demiplanes exist outside the schema of the Inner and Outer spheres.
 * Armageddon Echo
 * Circle Between
 * Crypt of the Dying Sun
 * Dimension of Dreams
 * Dimension of Time
 * Dead Vault
 * First World
 * Fleshwarren
 * Freehold of the Rogue Angel
 * Harrowed Realm
 * Immortal Ambulatory
 * Kakishon
 * Leng
 * The Lost
 * Machine Armory
 * Mnemovore
 * Prison of the Laughing Fiend
 * Ramlock's Hollow
 * Runeforge

Planar metaphysics
The mortals of Golarion have several philosophies that attempt to describe the metaphysical relationships of the planes to each other. The most prominent is known as the arcane tradition, also known as the orthodox scheme, which envisions the planes as nesting spheres of realities with the Inner Sphere at the center and Outer Sphere as the infinite exterior. In this model, the Positive and Negative Energy Planes govern the powers of creation and destruction in opposition to one another.

An alternative philosophy, known as the esoteric tradition or ancient wisdom, suggests that the Positive and Negative Energy Planes are instead complementary to each other, serving as the source and destination of all creation and forming a cycle that is temporally and dimensionally infinite. All forms of life in this cycle are part of the monad, a transcendental oneness that unites all souls into a single spiritual existence, with aeons existing closest to the source of creation and mortal souls existing further away. This tradition minimizes the role of the Outer Sphere as well as the Elemental and Transitive planes.
