Plane (Dungeons & Dragons)

This article is about planes of existence in Dungeons & Dragons. For other uses, see plane.

In the standard cosmology of the Dungeons & Dragons roleplaying game, the planes of existence are alternate dimensions. They can be grouped into five basic categories: the Inner Planes (places of raw matter and energy); the Outer Planes (places of gods, souls, and raw philosophy and belief); the Material Planes (worlds balanced between the philosophical forces of the Outer Planes and the physical forces of the Inner Planes, these are the standard worlds of fantasy RPG campaigns); the transitive planes (connecting the other planes and generally containing little, if any, solid matter or native life); and the demiplanes (minor, often artificial planes, often possessing qualities of the other four types of planes).

The planes as a whole are usually presented as a series of concentric circles, with alternating spatial and transitive planes; from the center outwards, they are ordered as follows: Inner, Ethereal, Material, Astral, Outer Planes, and the Far Realm. The Shadow Plane and the Dimension of Time, if they are included, are separate from the others, and usually represented as being connected to the Material Plane. Demiplanes, although most commonly connected to the Ethereal Plane, can be found attached to any plane. All planes, save the demiplanes, are infinite in extent.

Some Dungeons & Dragons settings have cosmologies that are very different from the "standard" one discussed here.For example, the Eberron setting has only seventeen planes in total, most of which are unique to Eberron.

Publishing history

In the earliest versions of Dungeons & Dragons, the concept of the Inner, Ethereal, Prime Material, Astral and Outer Planes was introduced; at the time there were only four Inner Planes and no set number of Outer Planes. In the original Advanced Dungeons & Dragons Players Handbook (First Edition), the full canonical layout of the planes was presented for the first time; this material was expanded upon in the original Manual of the Planes. The Plane of Shadow was a demiplane here, rather than a separate plane, and most of the Outer Planes went by different names. Many Outer Planes were renamed in Advanced Dungeons & Dragons Second Edition in the Planescape campaign setting. In the Third Edition Manual of the Planes, the old and new names were combined together, the Demiplane of Shadow was promoted to the Plane of Shadow, the Prime Material Plane was shortened to the Material Plane, and it was stated that there was one Ethereal Plane connected to each Material Plane.

Inner Planes

The Inner Planes are made up of elemental matter and forces. They consist of the Elemental Planes and the Energy Planes.

Material Planes

The Prime Material Plane is where the more 'normal' worlds exist, many of which resemble Earth. The 2nd edition Dungeon Master's Guide states there are several prime material planes, but several other 2nd edition products say there is only one Prime Material Plane rather than several.

The Outer Planes

The Outer Planes are the planes of belief and afterlife.

The Far Realm

The Far Realm is a plane far outside the others and often not included in the standard cosmology.

Transitive planes

Astral Plane

The Astral Plane is the plane of thought, memory, and psychic energy; it is where gods go when they die or are forgotten (or, most likely, both). It is a barren place with only rare bits of solid matter; some creatures, such as the tyrannous githyanki, use the petrified corpses of dead gods as floating fortresses. The Astral Plane is unique in that it is infinitesimal instead of infinite; there is no space or time here, though both catch up with you when you leave. The souls of the newly dead from the Prime Material Plane pass through here on their way to the afterlife or Outer Planes.

The most common feature of the Astral Plane is the silver cords of travelers using an astral projection spell. These cords are the lifelines that keep travelers of the plane from becoming lost, stretching all the way back to the traveler's point of origin.

God-isles

In the Dungeons & Dragons game, a god-isle is the immense petrified remains of a dead god. God-isles float on the Astral Plane, where githyanki and others often mine them for minerals and build communities on their stony surfaces. Tu'narath, the capital city of the githyanki, is built on the petrified corpse of a dead god known only as "The One in the Void." God-isles often have unusual effects on those nearby, including causing strange dreams of things that happened to the god when it was alive. God-isles are also the only locations on the Astral Plane that are known to possess gravity or normal time flows.

Ethereal Plane

"Ethereal plane" redirects here. For the mystical concept, see Etheric plane.

The Ethereal is often likened to an ocean, but rather than water it is a sea of boundless possibility. It consists of two parts: the Border Ethereal which connects to the Inner and Prime Material planes, and the Deep Ethereal plane which acts as the incubator to many potential demiplanes and other proto-magical realms. From a Border Ethereal plane a traveler can see a misty greyscale version of the plane from which they are traveling; however, each plane is only connected to its own Border Ethereal, which means inter-planar travel necessitates entering the Deep Ethereal and then exiting into the destination plane's own Border Ethereal plane. Many demiplanes, such as that which houses the Ravenloft setting, can be found in the Deep Ethereal plane; most demiplanes are born here, and many fade back into nothingness here. Unlike the Astral Plane, in which solid objects can exist (though are extremely rare) anything and everything that goes to the Ethereal Plane becomes Ethereal. There is also something here called the Ether Cyclone that connects the Ethereal plane to the Astral Plane.

In Dungeons & Dragons Third Edition, there is canonically one Ethereal Plane attached to each Material Plane; use of the Deep Ethereal is an optional rule.

Shadow Plane

Main article: Plane of Shadow

The Plane of Shadow was a demiplane in an earlier edition of the game, but finally became a full-fledged transitive plane in the 3rd edition cosmology. It is, as one would expect, an empty plane of darkness, where shadows are cast without any source of light. The Shadow Plane connects to other planes not only through portals but also through darkness; this is especially true on the Material Plane, where a monster or mage might use the shadows as a form of transportation. It has also been speculated that the Shadow Plane connects many different cosmologies, thus making it possible for a planeswalker to travel between them. The d20 Modern campaign's Shadow Chasers, Urban Arcana, and the d20 Past campaign Shadow Stalkers, are based on this premise. In the Dungeons & Dragons Third Edition this is an optional rule.

Mirror Planes

Mirror planes were introduced in the Third Edition Manual of the Planes as an optional group of transitive planes. They are small planes that each connect to a group of mirrors that can be located in any other planes throughout the multiverse. A mirror plane takes the form of a long, winding corridor with the mirrors it attaches to hanging like windows along the walls. Mirror planes allow quick travel between the various mirrors that are linked to each, but each plane contains a mirror version of any traveler that enters it. This mirror version has an opposite alignment and will seek to slay his real self to take his place. All mirrors connect to a mirror plane, though each mirror plane usually has only five to twenty mirrors connecting to it.

Phlogiston

Introduced in the Spelljammer setting, the Phlogiston is not traditionally considered a "plane" but acts very similarly to one. It is a highly flammable gaseous medium in which crystal spheres holding various Prime Material solar systems float, traversable by Spelljammer ships.

Temporal Plane

The Plane of Time was known as the Temporal Prime in the 1995 book Chronomancer. It is a plane where physical travel can result in time travel.

In 3rd edition products, some of the detail of Temporal Prime became incorporated into the "Temporal Energy Plane" mentioned in the 3rd edition Manual of the Planes. Dragon Magazine #353 associates it also with the "Demiplane of Time" that's appeared in various forms since 1st edition.

Demiplanes

Demiplanes are minor planes, most of which are artificial. Demiplanes are commonly created by demigods and extremely powerful wizards and psions. Naturally occurring demiplanes are rare; most such demiplanes are actually fragments of other planes that have somehow split off from their parent plane. Demiplanes are often constructed to resemble the Material Plane, though a few — mostly those created by non-humans — are quite alien. Genesis, a 9th level arcane spell or psionic power, is one of the few printed methods for a player to create a demiplane.

The most notable demiplane is the Demiplane of Dread, the setting of Ravenloft.

Portals, conduits and gates

Portals, conduits and gates are all openings leading from one location to another; some lead to locations in the same plane, others to different planes entirely. Although the three terms are often used interchangeably, there are notable distinctions. Portals are bounded by pre-existing openings (usually doors and arches); the portal is destroyed when the opening is. Portals also require portal keys to open; a key is usually a physical object, but it can also be an action or a state of being. Naturally occurring portals will often appear at random (a common occurrence in the city of Sigil, "City of Doors", in the Planescape campaign setting); some portals only exist for a brief period of time, or shift from one location to another. Conduits are also naturally occurring, but they are natural phenomena, the planar equivalent of whirlpools and tornadoes. Conduits are only known to occur in the Astral and Ethereal Planes. A type of conduit known as a color pool is a common gateway from the Astral Plane to the Outer Planes. A vortex is a link from a Prime Material world to the Inner Planes, which begin in areas of intense concentration of some element (e.g., the heart of a volcano might be a vortex to the Plane of Fire). There also used to be living vortices (plural of vortex) which the sorcerer-monarchs of Athas have managed to maintain, like siphoning water through a hose, and use to empower their "priests," the templars. Gates are portals that are not bounded by physical apertures; gates are rare, and usually appear as a result of magical spells and rare planar phenomena. Lastly, planar bleeding occurs when regions of two planes coexist; such phenomena are usually short-lived, and disastrous for their environs.

Planar pathways are special landscape features appearing in multiple planes or layers of a plane. Travel along a planar pathway results in travel along the planes. Pathways are crucial tactically, because they are very stable compared to portals or gates, and don't require magic spells or portal keys. One notable planar pathway in the Planescape campaign setting is the River Styx, which flows across the Lower Planes and parts of the Astral Plane. Another is the River Oceanus, which flows through the Upper Planes.

Alternative interpretations

In the context of the game, there are many theories of the organisation of the planes. For instance, in some lands it is believed that there are multiple Prime Material planes, rather than one containing all the worlds or planets. In these lands the Ethereal planes are believed to surround each Prime Material plane.

See also Alternative theories of the Outer planes.

Coterminous versus coexistent

Planes may border (be coterminous) or may be coexistent. In particular, the Ethereal and Shadow planes are coexistent with the Material Plane. In effect, the "boundary" between the two extends through all of space. Thus a ghost in Dungeons & Dragons, which is an ethereal creature, has a location on the Material Plane when it is near the border of the Material and Ethereal planes. It can "manifest" itself into the Material, and force attacks launched from the Material can hit it.

4th edition cosmology

4th edition uses a simplified default cosmology with only six major planes, each of which has a corresponding creature origin. The Astral Sea, Elemental Chaos, Feywild and Shadowfell are covered extensively in the Manual of the Planes, while the Far Realm is covered briefly.

The Astral Sea

One of the two fundamental planes, the Astral Sea corresponds to the Astral Plane of earlier editions. The Astral Dominions, counterparts to the Outer Planes of earlier editions, are planes which, float within the Astral Sea. Creatures native to or connected with the Astral Sea generally have the immortal origin.

Core Astral Dominions

• Arvandor, the Verdant Isles: A realm of nature, beauty and magic similar to the Feywild. Home to Corellon and (sometimes) Sehanine.
• Celestia, the Radiant Throne: A great mountain that drifts in a world of silver mists. Home to Bahamut, Moradin and, sometimes, Kord.
• Chernoggar, the Iron Fortress: The rust-pitted iron castle, where mighty warriors fight and die endlessly. Home to Bane and Gruumsh.
• Hestavar, the Bright City: As the name suggests, this dominion is a luminous metropolis, used by planar merchants. Home to Erathis, Ioun and Pelor.
• Kalandurren, the Darkened Pillars
• The Nine Hells: A place of sin and tyranny, a world of continent-sized caverns. Home to Asmodeus.
• Pandemonium
• Shom, the White Desert
• Tytherion, the Endless Night: A dark wilderness where serpents and dragons lurk. Home to Zehir and Tiamat.

The Elemental Chaos

One of the two fundamental planes, the Elemental Chaos corresponds to the Inner Planes of earlier editions (excluding the Positive and Negative Energy Planes), also containing some aspects of Limbo. The Elemental Chaos contains Elemental Realms, which are themselves planes, the Abyss is one such realm. Creatures native to or connected with the Elemental Chaos generally have the elemental origin.

Locations within the Elemental Chaos

• The Abyss: A place of utter evil and corruption, the result of a mad god's attempt to control the whole cosmos. Home to the Tharizdun, the Elder Elemental Eye. Lolth's home, the Demonweb Pits, can also be found here.
• The City of Brass: The Efreeti capital and a major trade hub planar trade and travel.
• The Keening Delve
• The Ninth Bastion
• Zerthadlun

The Far Realm

An anomalous plane, the Far Realm is a bizarre, maddening plane. Creatures native to or connected with the Far Realm generally have the aberrant origin.

The Feywild

One of the two parallel planes, the Feywild is a more extreme and magical reflection of the world with some thematic links to the Positive Energy Plane of earlier editions. Creatures native to or connected with the Feywild generally have the fey origin. This plane has some sort of connection to Arvandor, and is suspected that the Realm of Corellon can be reached by here.

Locations within the Feywild

• Astrazalian, the City of Starlight
• Brokenstone Vale
• Cendriane
• They Feydark
• Harrowhame
• The Isle of Dread
• Mag Tureah
• Maze of Fathaghn
• Mithrendain, the Autumn City
• The Murkendraw
• Nachtur, the Goblin Kingdom
• Senaliesse
• Shinaelestra, the Fading City
• Vor Thomil

The Shadowfell

One of the two parallel planes, the Shadowfell is a type of underworld, and the thematic successor to the Negative Energy Plane and Plane of Shadow from earlier editions. Creatures native to or connected with the Shadowfell generally have the shadow origin.

• Gloomwrought, the City of Midnight
• Letherna, Realm of the Raven Queen
• The House of Black Lanterns
• Moil, the City That Waits
• Nightwyrm Fortress
• The Plain of Sighing Stones
• The Shadowdark

The World

The equivalent to the Prime Material Plane or Material Plane of earlier editions, this plane lacks a formal name. Creatures native to the world geneally have the natural origin. The gods Avandra, Melora and Torog have their homes in the World. The god Vecna wanders the whole cosmos (Sehanine is prone to doing this, too).

Demiplanes

Demiplanes are relatively small planes which are not part of larger planes. The most prominent demiplane is Sigil, City of Doors.

Other anomalous planes

Anomalous planes are planes which do not fit into other categories. The most prominent of these planes is the Far Realm.

Other anomalous planes

• The Plane of Dreams
• The Plane of Mirrors
