Gehenna (/gɛˈhɛnnɑː/ ge-HEN-na or: /gɛˈhɛnə/ ge-HEN-uh[)

The four layers of Gehenna were infinite planes with gravity at a forty-five degree angle to the ground, making travelers feel as if they were on the side of a mountain with no base or peak. Anyone losing their footing could tumble for miles/kilometers before finding enough purchase on the slope to halt their fall. Nearly all terrain that was not a river of water or lava was slightly slippery to quite slick. All structures were either built onto or carved into the slopes. Heat and light came from the ground, but the source was volcanic: lava flows, vents, fumaroles, and mud pots were very common. Earthquakes and volcanic eruptions occurred often, tearing the land apart. On the hotter layers, unprotected flammable items and creatures would catch fire from the glowing ground or superheated gases being ejected. The barriers between layers were always underground, usually in dead end corridors.

Geography

Khalas

The uppermost layer, Khalas, was the most livable of the four planes with many waterfalls cascading down the slopes, the largest being the river Styx. The Styx followed a rough path down the slope, fell for thousands of feet/meters, ran through twisty rapids before finally disappearing into underground passages. Steam rose into the infinite and empty black sky making the horizon glow a dull red. Khalas touched the Astral Plane and had connections to Hades, the Nine Hells, and Concordant Opposition. The portals looked like black chasms in the floor of deep underground passages. Markings on the walls would often indicate the portal's destination, if you could read them.

Chamada

The second layer of Gehenna was the most violently active layer with lava cascades thousands of miles/kilometers wide and city-sized volcanoes yawning open on the slopes. The air was foul with acrid smoke for 10 miles (16 kilometers) above the surface and would cause blindness to unprotected eyes and had the effect of a stinking cloud on the lungs. Below ground the air was fresher but stank of burning flesh and hair.

Mungoth

Mungoth was a land of falling ash and burning snow. The furnaces of this layer were fewer and farther apart, allowing ice and snow to build up in the darker places between active areas. Travelers had to brave the never-ending avalanches of wet snow and fiery rock. Underground passages were relatively safe.

Krangath

The fourth layer was devoid of any volcanic activity, even underground. All was dark and cold. The name of this layer meant literally "dead furnaces". It is here where Irkallu, the realm of the Ereshkigal, is found. It sits in beak half-light as the souls of the dead simply exist.
