Outer Planes (3.5e Environment)
From D&D Wiki
In Dungeons & Dragons, the fantasy role-playing game, 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. 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. Most of these planes are split into 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.
 Standard D&D cosmology
The standard Dungeons & Dragons (D&D) cosmology 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 all of these sit the Neutral planes, or the Planes of Conflict. One further plane sits in the centre 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 portrayed in the Planescape setting as the incorrect names used by the "Clueless", or characters from the Prime Material unfamiliar with the planes.

 Alternative theories
Within the D&D setting, theories of organization of the Outer Planes vary according to culture. Nordic lands see the plane of Ysgard as dominant over all others, in accordance with the importance they ascribe the powers there. Some Oriental lands 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.
Most of the outer planes have sub-planes, which are called layers. The different layers are named, like the planes themselves. The different layers of a plane can greatly contrast with eachother.
Mechanus does not have any sub-planes. Limbo has 5 layers, but they are identical or nearly identical to eachother. The following are the various layers of the outer planes:
The Abyss has 666 layers, too many to list.

 Forgotten Realms cosmology
The Forgotten Realms cosmology was originally the same as that of a standard Dungeons & Dragons campaign. The cosmology for the 3rd edition of D&D was altered substantially so that it contained twenty-six Outer Planes, arranged in a tree-like structure around the central 'trunk' of the material plane of Toril. Unlike the Outer Planes of the standard D&D cosmology which were heavily alignment-based, the Outer Planes of the Forgotten Realms cosmology were faith-based. The planes of the Forgotten Realms were retooled in the 4th edition to match the new default cosmology, with many of the planes or realms being relocated to the Astral Sea, and a handful now located in the Elemental Chaos.
 Eberron cosmology
This is a description of the Eberron Cosmology prior to the Eberron fourth edition rules. For 4th edition cosmology information, please see World of Eberron.
The Eberron cosmology, used in the original Eberron campaign setting, contained thirteen Outer Planes in 3rd edition, and gained at least two for 4th edition under the new cosmology. They exhibit traits similar to those of the standard D&D cosmology but also some (Irian, Mabar, Fernia, and Risia) appear more like Inner Planes. The cosmology was unique in that the Outer Planes orbited around Eberron through the Astral plane, now they are floating like other planes in the Astral sea. As they orbited, their overlap with the material plane changed and access to those planes became easier or restricted.

Like most other D&D campaign settings, in 3rd edition D&D Eberron has a number of planes. Besides the Prime Material Plane, the Ethereal Plane, the Plane of Shadow, and the Astral Plane, the Eberron Campaign Setting has thirteen relatively unique planes. Gates or portals to any of the planes are very rare. These thirteen planes metaphysically orbit around Eberron, and depending on their current location are considered in one of four states.
- Waxing/Waning - The plane is either approaching or moving away from Eberron. Planar travel occurs as normal.
- Coterminous - The plane actually touches Eberron, and certain effects are strengthened in Eberron. Also, it may be possible to travel between planes by going to an appropriate spot. For example, when Risia, the Plain of Ice is coterminous, one may enter the plane from Eberron by walking into a blizzard. Because of seals placed by the Gatekeeper druids, Xoriat, the Realm of Madness, is incapable of becoming coterminous with Eberron.
- Remote - The plane is furthest from Eberron, and certain effects are weakened in Eberron. Also, reaching a remote plane with the spell plane shift is difficult and requires a high Spellcraft DC check. Because of the conflict between the Quori and the giants of Xen'drik, Dal Quor is always considered remote from Eberron.
 4th Edition Cosmology
In the 4th Edition, most of the Outer Planes have been replaced by Astral Domains in the Astral Sea. Known Astral Domains include Celestia and the Nine Hells. The Abyss is an exception; it is now located in the Elemental Chaos.
