Planescape

Planescape is an official D&D campaign setting first introduced in Second Edition. The setting centers around exploring an original multiverse cosmology. One of the more famous aspects of the setting is the distinctive artwork of Tony DiTerlizzi (you can see some of his art in the gallery section of the article).

Sigil

Don't let its slow flaying shadow fall on you

Sigil is a city built on the inside of a torus (imagine a tire lying on its side with buildings all around the inside surface). From anywhere on the Outlands (the most neutral of the Outer Planes), Sigil can be seen floating above the great stone Spire, but since the Spire is infinitely high, the only way in or out is through the portals that manifest themselves inside of doorways, windows, and any other kind of bounded space. Because of this, Sigil is also called 'The Cage'.

Portals like those in Sigil exist all over the multiverse, linking distant planes to each other, but the concentration is highest in the Cage. This phenomenon makes Sigil one of the most coveted locations in the multiverse. Gods and fiends would love to take over, but Sigil is guarded by a being called the Lady of Pain, whose diligence bars would-be conquerers from entering the city. Those within the city that displease the Lady find themselves either flayed alive by her shadow or cast into Mazes from which few ever escape.

Prior to the events of the Faction War adventure, Sigil's political and philosophical system is dominated by fifteen factions, all vying for the most believers (see Factions, below).

Inner Planes

The Elemental Planes (Air, Earth, Fire, and Water) are the most famous Inner Planes, but there are many other planes traditionally grouped into this category. These planes are:

The Positive and Negative Energy Planes

Realms of pure "healing" energy and the force that powers undead, respectively.

The Paraelemental planes

Intersections of Elemental Planes, such as Magma, the intersection of Fire and Earth, or Ice, the intersection of Water and Air.

The Quasielemental Planes

Planes formed from the interactions of the Positive or Negative Energy Planes and the planes of Fire, Water, Air, and Earth (such as Vacuum, formed from Air and Negative Energy, or Mineral, formed from Earth and Positive Energy).

The Inner Planes have their own gods and realms (see Powers under Outer Planes, below)

Outer Planes

There are seventeen Outer Planes, each formed from the moral and ethical alignments of the sentient beings in the multiverse. Most of the Outer Planes are divided into layers; the majority of portals deposit beings on the first layer of the plane. Many of the gods (or Powers) in the multiverse reside on the Outer Planes, in lands called realms that are under their direct control. The souls of those who worship these powers reform in their powers' realm upon death. If a being follows no power, their soul is instead drawn to the plane that most matches their alignment. Mortals also dwell on the Outer Planes; their alignment generally matches the plane they are on. Enough like-minded beings of another alignment can cause a portion of the plane to break off and appear on the plane that matches their alignment. The Outer Planes are:

The Abyss

Chaotic Evil. The Abyss has an infinite number of layers, each one unique and filled with hateful, unthinking evil. The tanar'ri (or demons, as they are known on the Prime Material Plane) dwell here.

Acheron

Lawful Neutral Evil. This is where the souls of those killed in senseless wars go, to fight among the armies of slain soldiers until they are killed a second time and merge with the plane. The first layer of Acheron is the most famous- an infinite realm of gigantic iron cubes, floating in the void, on which vast armies clash. The cubes occasionally collide, smashing anything caught between them to paste.

Arborea

Chaotic Good. This is the plane of the elven and Greek powers. It is typified by vast rugged geography, immense forests, mountains that peak above the clouds, and other splendors of nature.

Arcadia

Lawful Neutral Good. Arcadia is a plane of law first and good second. Day changes to night with no pause, and vigilant militias of dead paladins patrol the perfectly-straight roads. The formians -- a caste race of ant-centaurs -- are native to Arcadia.

Baator

Lawful Evil. 'The Nine Hells' of Baator are the domain of the baatezu (or 'devils'). There are nine layers to the plane, each more terrible than the previous. Avernus, the first layer, is a land of scorched rock, constantly bombarded by fireballs that tumble out of the sky.

The Beastlands

Neutral Good Chaotic. Relatively few sentient creatures live on the Beastlands, compared to the number of animals dwelling here - everything from ants and cats to dinosaurs. Most of the plane is wide-open savannas, deep primeval forests, and unfathomable oceans.

Bytopia

Neutral Good Lawful. The Twin Realms are stacked in a unique way- imagine them as the floor and ceiling of a great cave, connected by enormous stalactites and stalagmites that merge into each other. Unlike many other planes, where travel between layers is accomplished with portals, the two layers of Bytopia can be reached by climbing one pillar until gravity reverses and one finds herself climbing 'down' to the other layer. The beings that dwell here are industrious, cheerful, and helpful.

Carceri

Neutral Evil Chaotic. The 'Prison Plane' is where the souls of backstabbers and traitors dwell. Carceri is noted for being comparatively inaccessible; there are many portals leading to the plane, but very few portals leading out.

Elysium

Neutral Good. The Peaceful Plane is a land of soft fields, quiet woods, and calm waters. It is home to the guardinals, a race of animal-like celestials.

Gehenna

Neutral Evil Lawful. This plane is comprised of a series of immense double-ended volcanoes, floating in the void. Each volcano is its own layer. The yugoloths (or 'daemons') rule this plane in name, but there are several other powerful fiendish races that dwell here as well.

The Gray Waste

Neutral Evil. The Three Glooms are desolate lands where all color is muted to shades of gray. Visitors soon find their own color fading away, and their ambition soon follows, leaving them empty husks, devoid of emotion. The yugoloths are a powerful force on this plane, but the night hags and their larvae trade are the real power here. The tanar'ri and baatezu use the Gray Waste as their primary battlefield, as its metaphysical location is halfway between that of Baator and the Abyss.

Limbo

Chaotic Neutral. Limbo Limbo Limbo chaos ever-changing NO NOT THAT listen berk it's like every mad power CRUMBLING FROM THE INSIDE flowers rusting HOPE SPRINGS DIAGONAL

Mechanus

Lawful Neutral. The Clockwork Universe is comprised of immense gears (some of which are miles in diameter), each revolving in tandem with the cogs that connect to them. This is the most orderly of all the Outer Planes. The modrons reign here, from the Tower of Primus at the center of the great gear Regalus.

Mount Celestia

Lawful Good. The Seven Heavens are comprised of seven ascending peaks on a great mountain. The Mount is surrounded by the Shining Sea, an endless ocean of sparkling holy water. The archons oversee Mount Celestia, from the lantern archons that guide new pilgrims to the throne archons that watch over all else.

The Outlands

Neutral. This is the smallest of the Outer Planes, though it is still technically infinite. The best-known features of the Outlands are the Spire and the sixteen gate-towns that lie in a ring around the "edge" of the plane (imagine a pancake with a pen stuck in the middle- Sigil floats above the Spire, and the gate-towns form a ring around the edge of the pancake). Each gate-town is tied to one of the other Outer Planes, and each contains a permanently open portal to that plane somewhere inside. The gate-towns reflect the plane they lead to, and most inhabitants share the alignment of that plane. Between the gate-towns and the Spire are nine rings (the Outlands' version of planar layers). At the ninth ring, where the gate-towns are, magical spells function more or less normally. As one approaches the Spire, higher-level spells cease to function, starting with ninth-level spells and descending, to the base of the Spire where no magical spells function. Beyond the gate-towns are the Hinterlands, a strange area where space and time break down, and further movement away from the Spire is severely restricted.

Pandemonium

Chaotic Neutral Evil. The four layers of Pandemonium are nothing but an endless series of caves, cut through by a howling wind that never ceases. Exposure to this wind inevitably drives one insane. The first layer is the most open, and each below it becomes more cloistered. The final layer nothing but a series of air-pockets inside the endless rock. The worst monstrosities of the planes are imprisoned here by the powers. It is said that the Lady of Pain once sent her enemies here before she gained the ability to create Mazes.

Ysgard

Chaotic Neutral Good. Ysgard is most famous as the home of the Norse powers, but many other creatures live here, including giants and bariaur (a sort of ram-centaur unique to the Outer Planes). The entire plane is comprised of floating islands of rock--some the size of continents--drifting in an open sky. The undersides of most of these earthburgs burn with a constant magical fire, though in some places the earthburgs float flaming-side up.
