Minauros

Minauros was the third layer of the Nine Hells of Baator. It was an endless polluted swamp constantly battered by winds, acid rain, and hail, and pinpointed with various cyclopean cities of carved stone.

"There are more secrets — dead, alive, and otherwise — buried under the muck o' this layer than the Lady of Pain ever knew. I'll tell you a few, berk, for a price..."

Description
Minauros was best described as a great stinking swamp, a fetid marsh of mire, muck and misery extending further than one could possibly imagine. The plane was a dismal morass of reeking, rotting earth and inches of polluted, diseased water where the corrupting powers of poison and sickness were enhanced and recovery diminshed. Corpses and carrion were so ubiquitous across the hellish bog that stumbling was a constant problem, and the occassional falls they induced might be enough to kill from landing on a sharp, upthrust bone or falling unconscious and drowning in the unclean waters.

Much of Minauros was dominated by a dreary urban landscape, a kingdom in a state of endless disrepair constantly teetering on the edge of ruin. The structures that interspered the plane were in need of constant fixing, upkeep, or outright replacement, all characterized by flimsy materials, cheap construction techniques, and shoddy artisanship. There were cities of ornately carved stone, masoned in cyclopean fashion, but even these suffered from slow decline. Almost everything built in Minauros was left untended to inexorably slide into the bottomless mud, gradually collapsing into the gigantic sinkhole that was the plane. Nothing of value stayed in the bog for long, with any treasure of size, magic, or other notability fated to be destroyed or taken.

Geography
The black, putrid surface of Minauros was covered in thick layers of scum and dotted with a series of mud flats and cesspools. The bubbling, filthy waters dispersed various foul odors and yellow-green swamp gas faintly illuminated the murky, fog-shrouded air. In some places infernal heat rose up from below, boiling and steaming the dank waters and creating mud geysers, while others were so cold the water iced over. Beneath the slowing mud were deep pits, which combined with the other hidden dangers required travelers to cautiously slog their way through the unpleasant swamp. Deeper in the plane, the marshes eventually gave way to stretches of lifeless, cinder-choked trees and volcanic ridges, the obsidian and igneous rock meandering eternally through the swamp until toward the center the plane rose into a vast and tortured volcanic badland of ash-hills and slime-filled rifts.

The weather of Baator was not really weather as such, but rather vigorously regulated features of a lawful plane, all happening for a reason, and the steady, never-ending rains of Minauros were no exception. The dimmed, eternally overcast skies of Minauros ranged from brown to leaden  and roiled with fecund, drooping clouds ranging from slate gray to putrescent indigo. An incessant pour of oily, polluted acid rain pelted the soil from above,  creating a sound like hundreds of beaten drums. Usually this was followed by sleet, which struck travelers and stuck to them to create an icy coating that slowly melted into an oily residue irremovable while still on the plane. Lastly came the frequent and sudden rushes of jagged, flesh-flaying hail, composed of balls of polluted ice sometimes augmented with hooks, metal shards, and the still-sharp teeth of long-dead devils.

These changes in atmosphere were cyclical in nature, the other effects accompanying the rain. Hailstorms reoccured at least every five minutes and would take under half an hour maximum to return. The storms lasted anywhere between a few seconds and a couple minutes, made worse by the fact that the bitter winds of a raging storm made flying, the otherwise fastest method of travel, highly dangerous. Away from any kind of structure, the only shelter for those unfortunates caught outside was the ridges, hiding behind which was effectively the same as having none.

Cosmography
By Asmodeus's decree, no planar portals could connect directly to any layer of Hell besides Avernus. This meant that in general, if one wanted to get to Minauros they would have to go the layer above it, Dis, and find a portal, and likewise would need another to get to Phlegethos below. Portals existed from the City of Dis to the Sinking City and Jangling Hiter, as well as from the Sinking City to the lower city of Abriymoch in Phlegethos. It was also possible to reach Phlegethos from the lowest points of Minauros by way of constant dribbles of slimy water that sluiced into long and generally lethal falls.

There were also other means of getting to Minauros without interfering with the other layers. Offshoots and waterfalls of the River Styx could be found on every layer of Hell, and a landing of the Infinite Staircase was known to lead somewhere within Jangling Hiter.

World Axis
In the World Axis cosmology model, the Nine Hells were a planet-shaped astral dominion floating in the Astral Sea, no longer of infinite size nor consisting of layers. In this cosmology Minauros was a dark and brooding cavern about across and a few  high supported by colums of rock every  or so, the rain caused by the oily water seeping from the ceiling. It was reached by descending down a road lined with gibbets from the lower gate of Dis which gradually broadened out into the layer of Minauros. Traveling scores of miles down dripping steps cut into Minauros's mudy geysers would put one at the feet of great rocky columns before a steep descent to the blackened plains of Phelegethos.

In the World Axis, the Styx plummeted into Minauros from a fuming cavern in Avernus, slowly and sluggishly wandering on a long, dark jounrey before emerging in the icy seas of Stygia.

Notable Locations

 * The City of Minauros, the largest settlement in the layer and the seat of power of Mammon, Lord of the Third. It was constantly sinking into the swamp, so expeditions of petitioners and slaves were sent periodically to fetch volcanic rock to shore the city up and replace its streets.  It was rumored that beneath the city lay the ruins of an ancient city pulled from the Outlands.
 * Aeaea was the secondary realm of Hecate, the Greek interloper deity of magic and the moon.
 * Jangling Hiter, a city suspended by chains from the bottom of Dis, the second layer.
 * The realm of Pisaethces, The Blood Queen.

Inhabitants
The primary inhabitants of Minauros were bearded devils, chain devils, imps, and spined devils. However, also quite common here were barbed devils, who were charged with tracking and hunting down petitioners who attempted to escape. Lemures and nupperibos composed the remainder of the population.

Notable dukes that formed Mammon's court included the generals Bael, Caarcrinolaas, and Melchon; Focalor, Mammon's seneschal; and Glwa, Mammon's consort.
