"For untold eons, Eshebala ruled over Vulgarea, the 193rd Layer of the Abyss...content to revel in hedonism, corrupt the hearts of her dwindling followers and inflict petty cruelty. Yet, if there are days in the Abyss, there came one when she realized she despised her own province. She hated demonkind. She hated the Abyss. It had become unbearably tedious, spent...done. The burgeoning goddess decided she would dip her toe back into the lives of mortals, and quest to remember...to understand her own existence...But that was a lofty goal for a mind that had long ago begun to unravel. Instead...She is learning that all she has left is cruelty...and it was always cruelty that gave her power, so she now believes, to the woe of any who cross her path." Partly inspired by a scant notation by Carl Sargeant in 1992's TSR book Monster Mythology: "Eshebala is the foxwoman deity of vanity, charm, greed, and cunning. Her symbol is a female fox. Eshebala appears as a foxwoman, a shapely fur-covered female with a fox’s head, or as a beautiful young elf maiden. She is bedecked in rich clothing and jewels, and carries a silver mirror. Eshebala’s realm of Vulgarea can be found on the 193rd layer of the Abyss. She is wily and vain. She favors beautiful things and collects jewelry and art, the tackier and flashier the better. She prefers to overcome her opponents using subtlety rather than force, seducing and devouring out of boredom. She loves gossip, and always insists on being the center of attention. Eshebala is a patron of evil shapeshifters who use their wits and wiles before resorting to violence." Eshebala is a true chaotic evil demon goddess, behaving 100% true to form, and an extremely challenging opponent to take down for your players.

The battles of the Blood War have raged for longer than mortals have known life, the conflict's savagery and hatred fueling the dreams, desires and obsessions of the multiverse. One way or another, the war spills through all the layers of existence, and little escapes its influence. Some clashes have consequences that shake the Lower Planes. Others are far less meaningful - they're fought solely for the sake of violence and killing. "The Field of Nettles" is set in the aftermath of an especially pointless battle. The adventure rips the player characters from their comfortable lives and thrusts them into the Blood War full force. The goal is to cross one of the more infamous battlefields, seeing the scope and the power of the fighting - and hopefully coming away with a greater understanding of just how big the Blood War is. The adventure is designed for a party of 4-6 PCs of 5th-8th level. The characters don't get to save the multiverse, nor do they find the key to unlock the dark of any great secrets. But they might come to realize their importance (or lack of it) in the scheme of things. On the fickle borders of the planes, that can be worth almost as much.

Silently, ponderously, they float through the Astral Plane, mammoth isles of rock adrift in an endless sea of silver. Once they were gods.

Centuries past, Lady Ilse ascended to scion of House Liis by trading the archdevil Mammon what he wanted most: her immortal soul – and a diabolical betrothal. The triumph proved hollow, for every year on the eve of her fell covenant, she was beset by visions of Mammon and her foul promise. Seeking to save herself, she was buried alive, swaddled in the holy symbols of a dozen divergent faiths. This desperate ploy held Mammon at bay for centuries…but a devil can afford to wait a very long time. After hundreds of years, the last of the holy wards has fallen. The devil has come to collect his due. Tonight a storm crashes against the ancient manor house and forgotten spirits rise from the muck and mire. The fallen belfry tolls once more, announcing the hellish fete. As the adventurers arrive to explore the Black Manse, Mammon calls for his winsome bride. He will leave with a soul at the end of the night. The only question is: Whose?

She ran. Where to or for how long, she really couldn't say. The little flame of her oil lamp sputtered and went out a few times. She'd snap her fingers and make the wick flare to life, but she may as well have ran blind. The hallways were pitch black with soot and choked with smoke, every turn was a guess and every corridor a gamble. Unnatural screams echoed from every direction. Left, right, left again, was this the south or north end of the labyrinth? She had no idea. The next turn brought her face to face with a doorway completely consumed in blue fire. The room beyond was so bright she had to look through her fingers at it. A shadow covered her, a shape in the doorway: a hulking creature with a wolf-shaped muzzle and enormous pincers for hands, wreathed in the same blue flames. The screams were getting closer behind her, too. They had her cornered, again. The demon slammed its shoulders through the narrow opening, splintering the wood and stone. She dropped the lantern and let the wand in her sleeve fall into her waiting hand. With a word of power and a gesture, she appeared in the familiar bedroom: stuffy and reeking of wood smoke. She'd have to try again tomorrow, if she could remember. During an exploration on the sixth level of Undermountain, a strange invisible creature leads to a series of collapsed chambers that hide a forgotten secret and one of the most devastating forces known to the multiverse. Marambra Nyghtsteel, the forgotten apprentice of Halaster Blackcloak, has been locked away for an age deep within Undermountain. What point and purpose her forced seclusion has, only Blackcloak may know. When a spell consuming blue fire, known as The Spellplague is trapped within the chambers, a series of events have left Marambra, lost in her madness, struggling to survive.

Few planes possess the raw malevolence of the Infinite Layers of the Abyss. It is a place of random violence, appalling cruelty, and pure, unadulterated wickedness. Here, unreasoning malice rules, and countless demons torture and murder for the joy of it. The Abyss is innovative in its wretchedness, with each fleeting moment birthing new and awful psychotic acts of utter evil. Those who brave its depths find no relief from its corrosive nature, nor respite from the cancerous seeds of evil blooming within all who tarry here; they find only anguish, pain and if they're lucky, sudden, abrupt death.

A cold winter wind blows from the Scourge Mountains, but its origins are not of this world. And with it come horrifying stories of a fey who walks the land.

It is the Winter of the Witch…and if the archfey Koliada is not stopped, it could be the world’s last. “Winter of the Witch” starts with the PCs receiving an urgent but somewhat cryptic message from the skeletal knight, Sir Keegan. They find the skeletal knight a helpless victim of an aggressive interrogation by an undead minion of Orcus and his demonic thugs, who are attempting to extract the location of something called the Sun’s Sliver from the stubborn knight. The PCs fight their way into deep ruins, defeat the demon lord’s toadies, and retrieve the Sun’s Sliver. Once the PCs have recovered the Sun's Sliver, they must confront the Winter Witch in Winter's Heart, the witch's icy sanctum in the Feywild. Only there can they confront the cold-hearted archfey and save a section of the world from a wintery doom.
