[ Gehenna ] [ Khalas | Chamada | Mungoth | Krangath ]


Gehenna — Layer the Third

The burning acid snow slopes of Mungoth

The Crackling Furnace, the Twilight Flames, the Treacherous, the Burning Ice

Themes of the Layer: Mungoth embodies the themes of exploitation, corporate greed, and a staggering lack of compassion. 

The third mount of Gehenna is a treacherous, wasteland of flaming ice where the landscape itself seems to conspire against you. It’s a frozen desert peppered with volcanic vents that cast a ghostly twilight violet glow, at least, the ones that aren’t snuffed out by acidic snow and storms of caustic ash. The ground is a fragile crust of rock, frequently rocked by tremors and mudslides. The void surrounding the mountain is perpetually dark, with the only light being a dim, eerie violet from the death throes of the volcano. Snowstorms here are no ordinary blizzards; they are lethal mixes of ash and acid that will etch metallic armours and even strip unprotected flesh from bone. The air is filled with the acrid scent of sulphur and burnt flesh, a constant reminder of the layer’s hostility to anything mortal.

The Dangers of Mungoth

Less-than-safe tunnels of Mungoth

Mungoth is a frozen hellscape where the steep slopes are constantly shifting and quaking. The snow is deadly, burning through clothing and flesh alike, dealing damage to anyone unprotected by magic. Mudslides, a deadly mixture of ash, snow, and lava, frequently cascade down the slopes, threatening to engulf any unwary sod. While the stench of sulphur is not as intense here as in Chamada, it still permeates every nook and cranny, making the air heavy and difficult to breathe. Visibility is often limited by the constant snowfall and ash fall, making navigation perilous, and scouting out dangers a constant challenge.

All in all, life of the surface is a miserable existence. And this is why the extinct lava-tubes, caverns and underground spaces of Mungoth are so hotly contested. Deep inside the mountain there’s at least some residual warmth, with rocks that glow a dull red or violet. The deeper you go, the less the cold bites, but the more fiercely there caves are guarded. However, planewalkers should be warned that mudslides and lava-bursts can also fill the caverns, turning the subterranean refuges into potential deathtraps too. Ah, Mungoth! Always a delight. 

The Denizens of Mungoth

Why would anyone be barmy enough to travel to this accursed place? Well cutter, you’d be surprised. Firstly, of course, there’s the petitioners, who frankly don’t get a lot of choice. The sods who end up here were those with true ice in their heart, misers who did nothing when they could have helped by donating a coin, corrupt lawmakers who fabricate evidence to frame a sod just to get themselves ahead, or berks who lie to send an innocent to the gallows, to protect someone close to them.

The followers of Loviatar, Mistress of Pain, also make pilgrimage to her realm, Ondtland. Her domain is a place of suffering and harsh discipline, where her devotees come eagerly to seek her cruel embrace. No doubt they find in Mungoth’s burning caress a reflection of their own inner pain and a second harsh, unloving mistress in the environment itself.

As for planewalkers, well there’s a reason that they might come here too. The diamond mines of Mungoth yield the largest, clearest, purest blood diamonds of any in the Lower Planes. Some call them blood diamonds because of the colour, others because they’re so dangerous to extract, and yet more because the Blood War is never far behind when a new motherlode of gems is discovered. Dwarves and duergar, svirfneblin and tieflings, even adventurous humans come here to try and strike it rich. The most dangerous jobs are done by slaves, naturally, but even the slave-drivers take enormous risks.

A yugoloth fortress of Mungoth

Most end up in the dead-book, of course, and that’s partly because the surface of Mungoth also is home to the shira divs, who embody the deadly nature of the wild. These fiends prowl the icy wastelands, their brutal hunts a testament to the survival of the fittest. They revel in adding to the harshness of the environment, pushing their prey to its absolute limits. Apparently, that just makes the corpses taste even sweeter. Diamond-hunters beware, because the shira are diamond hunter-hunters.

Last, and certainly most, are the yugoloths. While they’re less numerous here than on Chamada or Khalas, there are still more than you’d want. The ‘loths come here for business, and you’d better bet that yugoloths you’re unlucky enough to encounter on Mungoth are even more secretive than usual.

Usually known as the shock troops of the yugoloth armies, nycaloths are brutish and powerful, resembling hulking demons with bat-like wings. In Mungoth, they serve as enforcers and guards, patrolling the slopes and ensuring that any cutters who come snooping around are swiftly crushed. They revel in the violence, finding great joy in the pain and suffering of others. You might also be surprised to see hydroloths here. There’s precious little water, but the hydroloths have a knack with the mudslides—guiding them away from locations important too yugoloth goals, and if that means they accidentally destroy a mining burg at the same time, well that’s just a bonus. But what are they defending? Well, cutter, that’s a dark for another time… you’ve not garnished me nearly enough jink for me to risk telling you that.

Mungoth is a reminder to us mere bashers of the destructive power of greed and exploitation. It’s a place where the very ground beneath your feet is a potential deathtrap, where the air is poison, and the snow burns. Only the most resilient and well-prepared mortals can hope to survive here, and even then, it’s a grim and thankless existence.
