Oinos

The Gray Waste — Layer the First

The Gloom of Anguish, the Battle Plain

Themes of the Layer: Oinos, the Gloom of Anguish, is the first layer of the Gray Waste—at least, it’s the layer that the Astral Plane is connected to. This accursed place is the very embodiment of relentless suffering and ceaseless conflict. The key battlefield of the Blood War, Oinos is a realm where the philosophy of evil is entrenched in suffering and decay. It’s a place where hope is but a memory, and survival is a constant struggle against the oppressive forces of darkness.

The Lay of the Land

The landscape of Oinos is a desolate, pockmarked plain of mud and dust, trenches and razor wire, strewn with the ravaged and decaying corpses of countless battles. The ground is scarred from eons of conflict, making it a treacherous terrain for any who dare to traverse it. Stunted trees and plants dot the land, only to be trampled by the relentless march of fiendish armies or wither under the toxic air. The very atmosphere of Oinos is tainted with disease, most notably the Wasting Sickness, a malady that drains the life force from those unfortunate enough to walk the cursed soil here. This sickness weakens a victim slowly, draining first their vitality and then their personality, until they are completely debilitated and ultimately perish.

The sounds of Oinos are a cacophony of pain and violence. Here, you can’t escape the echoing screams of the dying, the distant clashing of weapons, the low rumble and ozone tang of magic, and the pitiful moans of the wounded. The clashing of steel, the tearing of flesh, and the anguished cries of the dying form a grim symphony that never ceases. Even in moments of relative calm, the air is filled with the haunting moans of the wounded. This constant noise serves as a reminder of the endless Blood War that rages across the layer, a battle between the forces of Baator and the Abyss that shows no sign of abating.

Key Features of the Gloom

Khin-Oin, the Wasting Tower, is an awful monument to the yugoloths’ power and ambition. This towering structure, constructed from the massive spinal column of the first power who crossed the yugoloths, rises twenty miles into the air and delves just as deep into the ground. Once the seat of power for the yugoloths, Khin-Oin is now a desolate fortress, its throne room sealed and its corridors echoing with the whispers of ancient secrets. The Siege Malicious, a throne of immense magical power, sits at the tower’s zenith, awaiting any who would dare claim it. However, the current master of Khin-Oin, the ultroloth Mydianchlarus, has not been seen in nearly a century, leaving the tower in a state of eerie abandonment.

The River Styx, that dark and malevolent waterway, winds its way through Oinos, serving as a grim reminder of the pain and anguish that define the layer. Merrenoloths, the boatmen of the Styx, ply their trade along its shores, ever eager to ferry desperate souls out of this cursed place—for a steep price, of course. The Styx itself is a perilous river, its waters capable of erasing memories and sapping the will of those who drink from it.

The Heart of the Blood War

The Blood War, berk, is the grand and grim spectacle of eternal conflict between the fiendish legions of Baator and the chaotic hordes of the Abyss. Imagine the fiercest battles you’ve ever heard of, then amplify the brutality and scale tenfold. That’s the Blood War, a never-ending struggle that rages across the lower planes, with Oinos as one of its central battlefields.

Picture this: vast armies of devils and demons clashing in a tumultuous frenzy, their battles rolling across the bleak plains of Oinos in unstoppable, destructive waves. The air is thick with the stench of blood, brimstone, and decay, while the ground is scarred and pockmarked by countless skirmishes. Weapons clash, claws rend, and magic crackles as these fiends tear into each other with a savagery that defies mortal comprehension.

In Oinos, the devastation is absolute. The landscape itself is scoured by the ferocity of the Blood War. The once flat and featureless plain is now a chaotic terrain of craters, trenches, and decaying corpses. The ground is littered with the remnants of war: shattered weapons, broken armour, and the bodies of the fallen. Everywhere you look, there’s evidence of the unending conflict—be it the blood-soaked soil or the charred remains of demonic and devilish siege engines.

The Field of Nettles is perhaps the most infamous battlefield in Oinos. This sprawling expanse of rocky ground and towering nettles, each capable of draining the blood from those they prick, is fed by the unending carnage of the Blood War. Here, fiends clash in epic battles, their blood nourishing the vicious plants that grow ever taller and more dangerous. The Field of Nettles is a grim shopping ground for scavengers too, who pick through the corpses for useful items, all while trying to avoid the fiendish scouts and the life-sapping essence of the Gray Waste.

Denizens of the Gloom

Important cutters to avoid in Oinos include the night hags, who herd their grotesque larvae across the desolate plains, and the press gangs that rove the battlefield, conscripting the living and the dead alike into the eternal conflict. Anthraxus, the former Oinoloth, once ruled from Khin-Oin with a leprosy-riddled fist, but his whereabouts are now unknown, leaving a power vacuum that the lesser fiends vie to fill.

In Oinos, the dangers are many. The ever-present threat of the wasting sickness, the perilous terrain, and the ceaseless conflict all conspire to crush the spirit of any who enter. Yet, the greatest danger of all is the layer’s insidious ability to drain a traveler’s very essence, leaving them a hollow shell devoid of hope and will. Oinos is a place where the philosophy of evil manifests as unrelenting suffering and decay. Its a realm where the clash of fiends and the stench of death permeate every corner, a battlefield where hope is a forgotten dream and survival is the only goal. The cursed land of Oinos embodies the true horror of the Gray Waste, a place where despair reigns supreme and the cycle of death and conflict never ends.
