It is the plane of exile.

It is the prison plane of the mulitverse

It is where the overthown plot their return. . .

Carceri may seem the least overtly dangerous of the Lower Planes, but that first impression quickly disappears - acid seas and sulfurous atmospheres may be rare on this plane, but the danger of Carceri is a subtler thing. This is the plane of darkness and despair, of passions and poisons, and of kingdom-shattering betrayals. On Carceri, hatreds run like a deep slow moving river, and there's no telling what the flood of treachery is going to consume next.

It is said that a prisoner on Carceri may only escape when she has become stronger than whatever imprisoned her there. That's a difficult task on a plane whose very nature breeds despair, betrayal, and self-hatred.

Carceri is called the sixfold realm because it has six layers nested within each other like little wooden dolls. On each layer, a strange of small planets stretches in two directions towards infinity.

Some of Carceri's layers are battle-scarred and wasted, the legacy of the Blood War. While much of Carceri remains oblivious to the war raging across the lower planes, portions of the plane are used as staging grounds or even battlefields.


The first layer of Carceri is a realm of vast bogs and quicksand. The River Styx runs freely through the layer, saturating the ground with its magic. Channels carved into the soft ground through eons of erosion are wide and deep. Where there is no river, there are swamps. Though patches of dry ground exist, they are rare and usually climb swiftly to rugged mountains where enraged titans dwell.

Mosquitoes swarm the air above the bogs, annoying travelers. Even more annoying are the smooth-talking petitioners that populate this dreary realm.


The orbs in the second layer of Carceri are covered with fetid jungles and scarlet plains. The stench of decay fills the air, a rot fueled by acidic secretions of jungle plants. Those without immunity to acid are soon rendered down to their component materials if they stay too long amid the swaying trees.

The plains of Cathrys are more habitable. Vast wind-swept grasslands cover the planes. Some patches possess razor-sharp leaves, which can cut a traveler not mindful of them to ribbons.


The third layer of Carceri is filled with sand. Stinging grit is driven so hard by the wind that it can strip and exposed being to the bone in a matter of hours. Sandstorms are frequent, as are tornadoes.


The fourth layer of Carceri is a realm of mountains so tall, rough, and cruel as to stagger the imagination of a traveler from one of the Material Planes. Travel on foot here is almost impossible, because the land is divided by canyons miles deep where it is not lifted to absurd heights by mighty tectonics. A few trading routes do exist, usually in the form of rickety bridges and cliff face trails barely wide enough for one.


Each orb of Porphatys is covered in a cold shallow ocean fed by constant black snow. The snow and water are mildly acidic.

Artificial structures do not last long in Porphatys. Small islands barely taller than sandbars rise above the waves. Most petitioners crow from atop the small sandbars, promising anything to those who can take them away.


The coldest layer of Carceri is also the lowest - or innermost, given the nested nature of the plane. Unlike the other layers, Agathys has only a single orb: a sphere of black ice streaked with red. The Necromanteion, citadel of the deity Nerull, watches over the otherwise deserted ice layer.

On the ServerEdit

There is a portal near the Mercykiller's Prison in the Lady's Ward that is said to lead to an island in Porphatys. This island is larger than many, and holds a prison.

Brave travelers should note that this portal is only one way. Those who enter will have to find another way out of the prison plane.

Protection from acid is also advised.
