Outer Planes

An outer plane is one of a number of general types of planes of existence. They can also be referred to as godly planes, spiritual planes or divine planes. The Outer Planes are home to beings such as deities and otherworldly creatures such as demons, celestials and devils, and they are the standard afterlife of mortal souls. Each Outer Plane is usually the physical manifestation of a particular moral and ethical alignment and the entities that dwell there often embody the traits related to that alignment.

The intangible and esoteric Outer Planes—the realms of ideals, philosophies, and gods—stand in contrast to the Inner Planes, which compose the material building blocks of reality and the realms of energy and matter.

All Outer Planes are spatially infinite but are composed of features and locations of finite scope. Many of these planes are often split in to a collection of further infinites called layers, which are essentially sub-planes that represent one particular facet or theme of the plane. For example, Baator's geography is reminiscent of Hell as depicted in Dante's The Divine Comedy. In addition, each layer may also contain a number of realms. Each realm is the home to an individual deity, or occasionally a collection of deities.


The first layers of each of the Outer Planes touch the Astral Plane. The Outer Planes are connected to the Prime Material Plane via Astral conduits, which are described as great silvery tubes or whirlwinds used by souls to travel to and from the afterlife. On the Material Plane, they are invisible to mortal sight. They are often watched over by mysterious spiritual guardians who resemble the psychopomps of mortal legend.

The various realms and layers of the Outer Planes are connected to one another via planar conduits, similar to the Astral conduits except they knit the Outer Planes to one another instead of to the mortal plane. They are also connected by a network of portals of varying appearance known as the Great Road. Many of these portals are surrounded by gate-towns or fortresses; these settlements are subject to sliding into the neighboring plane if their philosophical outlook changes too greatly, and planar entities and factions often compete to make this happen or to prevent it. Finally, there are the planar paths, such as the Infinite Staircase, Mount Olympus, Yggdrasil, the River Oceanus, and the River Styx, which cross from one plane to another without a need for portals or conduits.

Known Outer Planes

The cosmology used in the Greyhawk setting contains seventeen outer planes. Cosmologically, they are arranged in a ring of sixteen planes with the good-aligned planes, or Upper Planes, at the top, and the evil-aligned planes, or Lower Planes, at the bottom. The lawful planes (or Planes of Law) sit to the left, and the chaotic planes (or Planes of Chaos) to the right. Between the planes of Law and Chaos sit the Neutral planes, or the Planes of Conflict. One further plane sits in the center of the ring, the Outlands, being neutral in alignment. At the center of the Outlands is a Spire of infinite height; the city of Sigil floats above the Spire's pinnacle. The standard D&D cosmology is the official cosmology used in the Planescape and Greyhawk campaign settings. Many of the alternative names derive from the 1st-edition Manual of the Planes (1987, ISBN 0-88038-399-2), and were portrayed in the Planescape setting as the incorrect names used by the "Clueless", or characters from the Prime Material Plane unfamiliar with the planes.

Alternative theories

Theories of organization of the Outer Planes vary according to culture. Suel barbarian lands might see the plane of Ysgard as dominant over all others, in accordance with the importance they ascribe their god Kord there. Some of the lands of Oerik west of the Baklunish Basin see the planes not as separate regions, but as a single mass throughout which are scattered different agencies of the Celestial Bureaucracy, with the Celestial Emperor residing on one plane, and his Minister of State on another.

In the 4th edition of the Dungeons & Dragons game, the Outer Planes have been replaced with (or renamed as) the Astral Dominions in the Astral Sea.
