The Abyss or more fully, the Infinite Layers of the Abyss, is a chaotic evil-aligned plane of existence. It exists as one of a number of alignment-based Outer Planes that form part of the standard Dungeons & Dragons (D&D) cosmology.

Description

The description of the Abyss varies some between different editions, campaign settings and even individual accessories. This can be viewed as canonical status of the plane of the Abyss changing, or as an in-character explanation that the conflicting information is the result of misinformation spread by the demons themselves, and of misunderstandings by those who study them.

One description of the Abyss presents it as a region of intense, extreme, and unforgiving climates, with layers consisting of overwhelmingly fierce desert sandstorms, explosively unstable volcanic activity, boiling lava, and molten rock, blinding, sub-zero Arctic glaciers, bottomless oceans filled with enormous leviathans, heaving mountains of flesh, nauseatingly putrid environments saturated with disease-causing fungi, and the endless, existential void of infinite space.

The Fiendish Codex I: Hordes of the Abyss sourcebook suggests the possibility that the Abyss is actually alive, and that it spawns demons out of its urge to spread chaos and destruction.

Inhabitants

The Abyss is the home of one of the principal combatants in the blood war, the tanar'ri, a class of demon that rule the plane. Various other chaotic evil creatures and deities inhabit the plane, including undead and even some renegade celestials.

The petitioners of the Abyss are called manes. They have pale white skin, sharp teeth and claws, and maggots are reported to crawl through their flesh. Manes that survive for many years may be promoted to lesser forms of demon.

The demon lords inhabit the Abyss, including Demogorgon, Graz'zt, Lolth, and Pazuzu. Many evil deities make their home here including Vaprak, the Great Mother and Diinkarazan, a mad, imprisoned deity of the derro.

Structure

Like other outer planes, the Abyss is spatially infinite and supposedly consists of an infinite number of layers, or sub-planes.

The first layer shares its borders with the neighboring planes of the Windswept Depths of Pandemonium, the Outlands, and the Tarterian Depths of Carceri; travel is possible between the Abyss and these planes at certain locations. The portal to the Outlands gate-town of Plague-Mort is found beneath the town of Broken Reach in the Abyss. Most other portals to neighboring planes take the form of dark pits in the ground, indistinguishable from those pits that lead to lower layers of the plane.

The River Styx flows through the Abyss to many other lower planes, and as such can be used to gain access to those planes. In the Abyss, it is known to flow through the layers of Pazunia, Wormblood, the Blood Shallows, the Sighing Cliffs, Thanatos, the White Kingdom, Shedaklah, Shendilavri, Goranthis, Durao, and Gaping Maw, among others.

A gate to the Abyss exists in the dungeons beneath Onyxgate in Nyrond.

Layers

The Abyss is said to consist of an infinite amount of layers, though the total number of layers is also quoted as 666. Layers are numbered based upon order of discovery by various personalities in the background details of the game, as documented by the Fraternity of Order faction of the Planescape setting. Discrepancies in layer numbers between supplements and sources can be explained as catalogs that have been compiled by different sources.

It is impossible to know with any certainty whether layers are actually arranged in this precise order, in contrast to the known ordering of layers within all the other planes of the D&D cosmology. A useful metaphor is a deck of playing cards shuffled and then tossed down so they are piled together loosely, randomly, and sometimes not at all.

A list of layers named so far in D&D supplements includes:

• 1—Pazunia (also known as The Plain of Infinite Portals or The Palace of 1001 Closets) has been described as an infinite plane with only three types of distinct features:
  • The river Styx flowing through it (as it does through the top layers of other evil planes).
  • Large sinkholes which connect to other layers of the Abyss, some were drilled intentionally by ancient demons during the Abyss' original exploration. The largest of these holes is the Grand Abyss.
  • Iron Fortresses which guard the physical bodies of Demon Princes when they leave the Abyss to travel astrally.
