Phlegethos, the Fourth Layer of the Nine Hells, is a churning hellscape of volcanic devastation—an endless realm of lava rivers, geysering magma, and scorched obsidian plains. Governed in uneasy tandem by Belial and his daughter Fierna, it serves as Baator's judicial crucible, where punishment is both spectacle and principle. Fire is omnipresent and sentient, judging the worth of souls and igniting only those it deems unworthy; native devils and sanctioned travelers are spared its wrath. The Pit of Flame stands as the layer’s cruel court, where sinners are cast and slowly reduced to ash while their crimes are etched in living fire. The city of Abriymoch, carved into a vast caldera, thrums with infernal bureaucracy and smoldering intrigue. Spinagon devils toil amid fuming refineries and molten forges, while barbed hamatulas enforce order. Rich in infernal minerals and arcane heat, Phlegethos pulses with power and peril, a realm where law burns hot and ambition burns hotter.

Under a soot-black sky, rivers of lava snake across cracked basalt fields, casting an eerie red glow. Ash drifts like snow, coating jagged hills and crumbling obsidian spires. In the distance, the city of Abriymoch rises from a blazing caldera, ringed with flame-lit towers. Smoke veils the horizon, pierced by eruptions that stain the sky. Infernal figures march through the glow, shadows dancing in firelight.
