The Hells

The Fifteen Hells make up a single outer plane. The Hells are a remnant of the former plane Malumbris, which split into the Hells and the Abyss during the First Era. The Hells, together with the Abyss and Gehenna, are known as the Lower Planes. The Fifteen Hells is a Lawful Evil-aligned plane.

Inhabitants
The Hells are inhabited by the race of fiends known as devils. Each layer of the Hells is ruled by an archdevil, along with any lieutenants that they may have. The devils assemble large armies to fight the Blood War, but more often than not end up fighting each other as they vie for power.

Society
The Hells are a political nightmare; each devil, from the lowest imp to the mightiest archdevil, endlessly plots and schemes for ways to gather and hold power. Lying and backstabbing is a way of life, and necessary for survival.

The key commodity bought and traded for in the hells are mortal souls. The more a devil has and consumes, the more powerful they grow.

Layers
There are fifteen layers of hell, each ruled by a powerful archdevil.

Avernus
Avernus is the first layer of hell, and it is ruled by Zariel, the archdevil of falls from grace. Avernus is a vast wasteland of charred, ashen plains, the result of thousands of years of fighting from the Blood War. The terrain is treacherous, marred by obsidian rocks and boulders, and the starless, cloudless sky is filled by a red light.

Dis
Dis, the second layer of hell, is largely covered by an enormous city of the same name, located in a valley surrounded by a ring of spiked mountains. The layer is shrouded by a dark, hazy smoke, and every surface is hot to the touch. It is ruled by Dispater, the archdevil of strife.

Tigelidus
Tigelidus, the third layer, is a maze of dark, cramped caverns. No natural light exists here, and any artificial light shines only half as far as it would in any other plane. The ruler of Tigelidus is Zetin, the archdevil of fear.

Solitspes
Solitspes is the fourth layer of hell, ruled by Nucan, the archdevil of hopelessness. Solitspes is a endless barren waste, across which blows harsh, dry winds. The ground is made of soft sand that makes movement difficult.

Minauros
Minauros is the fifth layer of hell. It is a polluted swamp, constantly battered by winds, acid rain, and hail. It is ruled by Mammon, the archdevil of greed.

Phlegethos
Phlegethos is the sixth layer of hell, and it is ostensibly ruled by Fierna, though her father Belial also holds a great deal of power on the plane. Phlegethos is a blazing desolation of fire and lava. The sky is filled with smoke from the continuously-erupting volcanoes that dot the layer.

Insanitis
Insanitis is the seventh layer of hell, home to Dorunar, the archdevil of madness. Insanitis is a mess of a layer, with space behaving in odd and irregular ways often contrary to the laws of reality.

Degcrassa
Degcrassa is the eighth layer of hell. It is run by Forgath, the archdevil of the grotesque. The layer is full of heaps of garbage and rotting corpses stacked into large mounds to the point where the original ground of the layer is no longer visible.

Stygia
Stygia is the ninth layer of hell. Stygia is run by a vast, frozen ocean full of glaciers and peaks of ice. The ruler of Stygia is Levistus, the frozen archdevil.

Malbolge
Malbolge is the tenth layer of hell. and serves as a prison in the hells. It is ruled by Glasya, the daughter of Asmodeus.

Mendac
Mendac is the eleventh layer of hell, a large, frozen wasteland where icy winds blow buffet all who dare to travel it. It is the home of Kestal, the archdevil of betrayal.

Adoleb
Adoleb is the twelfth layer of hell, home to Balzu. Adoleb is a fiery landscape made of burning sulfur interspersed with hard stone land masses.

Maladomini
Maladomini is the thirteenth layer of hell, ruled over by Baalzebub. Maladomini is a once-lush wasteland, destroyed after the archdevil's betrayal of Asmodeus.

Cania
Cania is the fourteenth layer of hell, and it is ruled over by Mephistopheles. Cania is made up of moving icebergs and glaciers that constantly shift and collide with each other. The weather is freezing, and a harsh wind blows across the plane.

Nessus
Nessus is the home of Asmodeus, and is the fifteenth and lowest layer of the hells. It is a featureless plain with jagged structures jutting out of the landscape.
