The Nine Hells

The Nine Hells, more commonly referred to simply as Hell, is one of the Outer Planes of the Planescape. As the name suggests, Hell is comprised of Nine individual layers, each layer having it's own unique appearance and atmosphere. Running through each of Hell's nine layers is the River Styx.

Avernus
The first layer of Hell, Avernus is an expanse of badland-like plain. The horizon expands out in every direction, and the never-shifting sun sits directly overhead at all times, drying all moisture to the point that few things if any grow and the ground is reduced to cracked earth. Floating in the sky is a grand citadel next to a featureless, grey cube that is chained to one of the citadel's towers. A single town exists on the banks of the River Styx, and otherwise the plane is an uninhabitable desertscape.

Dis
The second layer of Hell, Dis is warm like Avernus, but not to the same extreme. It is a musky, humid heat permeating the plane of swamp-like ground surrounding a labyrinthine structure around the Iron City of Dis, which covers most of the usable land of the plane.

River Styx
A river of blood and souls, the River Styx acts as the final resting place for souls lacking the willpower to fully constitute a proper Soul Vessel. Charon's Ferry travels along the river, collecting power from wandering souls to fully form those with sufficient willpower. These souls are then distributed through the lower planes at Charon's discretion.

Avernus' Trading Outpost
The single town in all of Avernus, the Trading Outpost acts as a point for individuals to come to Hell and purchase fresh souls who find their afterlife in these unforgiving circumstances. Items are traded more than currency, but all manner of things could be found in the Outpost before the Aberrations siege on the settlement.

Thuldor
A small settlement carved in the bedrock beneath the River Styx in Avernus, it acts as a safehaven for wandering souls lost in the top layer of Hell.

Iron City of Dis
An expansive city of Devils living out their status, flanked with slaves of both Hell-bound souls and lesser Devils. All sorts of debauchery and indulgence can be found in any nook or cranny of the city. Less a punishment for the damned (though soul-slaves experience their own form of torture here), the City of Dis acts more as a personification of everything a mortal could do to find their end in one of Hell's many layers.
