Iggwilv. Orcus. Maleanthet. Obox-Ob. Charon. These names are among the most notorious in the multiverse, appellations belonging to some of the most dangerous and powerful creatures on the lower planes. Heroes from countless worlds have raised their arms against these immortal foes and, in most cases, these heroes have perished to their soul-blasting, life-ending might. Their lairs are notorious as they are: the River Styx, beautiful but deadly Shendilavri, the Gray Wastes of Hades, frozen Thanatos, and mind-numbing Zionyn. Simply entering one of these scions of evil is akin to suicide.

In ages past, the wizard Karavakos made a deal with devils, which resulted in him being trapped in an extradimensional pyramid, unable to escape. His only hope for escape is to lure adventurers into the Pyramid, in hopes that they will destroy his splinters and return his power to him. But his wife Vyrellis, whom he slew in a rage when the Pyramid formed, still lingers in spirit and wants nothing more than to see him laid low... Although set to allow PCs to just fight through each encounter, tips are included for PCs negotiating with the factions trapped in the pyramid.

The yuan-ti anathema, Hessatali, calls out to his yuan-ti faithful from his prison in the Abyss.

"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 temporarily weakened dome reseals above them, and they are left to explore the golden palace of Zahadran, once seat of power for the legendary Caliph Ardishir the Magnificent.

A terrible plague has swept through the city of Cairdus, and despite the local clergy’s best efforts, they have been unable to control the spread of the disease. Even those who seem cured often contract the disease again. The only thing that is making any headway are the special blessings given by the powerful Baron Velstaf, but he only grants these blessings for a price that few can afford. The Star of Olindor is an adventure designed for 7th-level rogue, or other character of similar abilities. The obstacles in the adventure are set up to encourage the use of stealth and trickery, and many rely on classic rogue skills. The adventure takes place in the city of Cairdus, the details of which have been intentionally left imprecise, so that it can be easily slipped into an existing campaign, or better yet the adventure can be altered to take place in any existing city. Part 1 of the Olindor Trilogy.

The Tale of The Haunted Ravine is a Hex Crawl Adventure of Exploration that can be used for any game system but was designed for use with D&D 5e. A Hex crawl map and random roll tables are used to create surprising encounters and mysteries for your players to interact with. Wild necrotic magic, magical mutations, undead, lost souls, and demons all cloaked in a fog fog-choked landscape; forsaken by the gods and scarred by the battle fought here long ago. Will your adventurers survive and escape the Haunted Ravine? Or will they join the legions of cursed souls imprisoned in this corrupted land?

The Underdark is a subterranean wonderland, a vast and twisted labyrinth where fear reigns. It is the home of horrific monsters that have never seen the light of day. It is here that the dark elf Gromph Baenre, Archmage of Menzoberranzan, casts a foul spell meant to ignite a magical energy that suffuses the Underdark and tears open portals to the demonic Abyss. What steps through surprises even him, and from that moment on, the insanity that pervades the Underdark escalates and threatens to shake the Forgotten Realms to its foundations. Stop the madness before it consumes you! Note for DMs: This adventure is not for the faint of hearted, to run or to play. The module starts with 10 NPCs traveling with the party through the grueling Underdark. This number can grow. The encounters within the book are often incredibly deadly for the characters that would be going through it. This is because the module expects them to run or talk their way through the events, or, in some cases, the module expects them to lose. If your players aren't the kind of party to run, talk, or surrender, do not get this adventure. The module almost requires that you use milestone leveling because the experience provided does not commonly get players to the levels they should be once they get to certain milestones in the story (7th when they leave the underdark, 15th when they face the demon lords.) Good luck and happy questing.

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?

"Bloodwood of the Cruor Circle" is an alseid and blood hag lair suitable for four or five 10th-level characters. This adventure can be completed in a single session. The Cruor Circle, a coven of dark druids led by a blood hag, has taken over control of the local alseid herd with the power of the blood. Within the forest, those who do not make proper sacrifices are stalked by the alseids and taken to the Bloodwood. Within the Bloodwood, captives become blood sacrifices, empowering the creation of sap demons, blood ponds, and other twisted products of the dark druids.

In this town, nothing goes like clockwork. A voice in the darkness offered him power, with only one string attached: first he had to find some adventurers. A fiend and minions of the plane of fire have set up shop beneath a small town, and have been attracting evil minions to their lair! In this town of Jenkel, the religious leader (named Broderick) is secretly under the influence of the demon and has been doing her will out of his own greed for power. A tilted pyramid appeared in the town years ago, and is actually the tip of a tower buried in the town. The tower leads to a dungeon and a shrine where the party can fight off the demon and rid the town of the evil influence. Pgs. 18-31

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.

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. Cold, beautiful, and deadly, she turns every mortal she touches into a statue of ice, and she seems determined to blanket the entire north in a blanket of frost. 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.

The Wells of Darkness is the seventy-third layer of the Infinite Planes of the Abyss, a prison used by demon lords and a graveyard for creatures the multiverse would rather forget. Imprisoned in one of these wells is Shami-Amourae, the Lady of Delights.
