Written by the setting’s creator, incomparable RPG author Monte Cook, Ptolus: Queen of Lies is an action-packed fantasy adventure painstakingly re-designed for Ptolus: Monte Cook’s City by the Spire. Involving numerous challenging scenarios for characters of 11th level, Queen of Lies is filled with dozens of dark elf personalities, cunningly showcasing their alien culture—a world of merciless betrayal and sinister lusts. Deep below the surface, in the sunless lands of the Netherdeep, creatures of darkness build weapons and amass armies, dreaming of invasion. An attack on a peaceful elven shrine in Emerald Hill sends the heroes on a quest to retrieve stolen artifacts and kidnapped friends. All signs point to the actions of the dark elves of Ul-Drakkan, far below the city of Ptolus. However, even within that ancient fortress, there exists a deeper darkness.... Underground enemies lurk beyond every twisting passage, and strange creatures abound. The foul culture of the dark elves is both decadent and cruel, and the heroes may discover that they’ve stumbled into a web of deceit and treachery spun by the self-styled queen of the dark elves. Can the player characters complete their mission without being discovered, or will they find out, perhaps too late, that their actions been orchestrated all along by the wicked Queen of Lies?

When a series of grisly murders and raids on farms and fishing boats come to light, accompanied by a strange fog, the people of Elmwood need heroes to investigate and stop the attacks. There is hardly anyone in the Moonsea who’s life hasn’t been touched by one of the tragedies over the past years, and these attacks may have deeper causes than anyone knows. Part of the Elmwood Adventures Series

"The creatures are just too intelligent, too crafty, and too strategy-minded to "rampage." Rampaging brings the wrath of oath-bound knights, powerful mages, and divinely-protected priests. Why would a dragon want such attention, unless it had some special secret, or unless it was insane? Or both. The northern reaches of the Derideth Swamp were once plagued by a rampaging dragon. This black dragon, named Storamere, took a mad glee in attacking human villages, wiping out orc camps, driving off the lizardfolk, and decimating farmland. He met his untimely end, though, in an ambush devised by the monks of the Order of St. Chausle. Storamere died with a curse upon his draconic tongue: "you could not have defeated me in my lair," he told his slayers. "I am forever invincible in my lair." Now Storamere is back, with a horde of his misshapen half-dragon offspring, to have his vengeance. All that remains of the once-heroic monks are two old men driven mad by their last encounter with the black dragon, so it falls to a band of adventurers to again defeat the mighty dragon -- this time in his palace, where the boastful Storamere claims he is at his strongest." Includes maps and damage rules for navigating Storamere's lair, a semi-solid palace made of a dangerous, corrosive liquid five feet thick and located on the ethereal plane. Most of the monsters in the lair have the Half-Dragon template applied. Published by Atlas Games

The PCs must infiltrate a city ruled by monsters to search for the spymaster that holds the key to saving a besiged nation.

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.

An introductory adventure set in and under Shadowdale after the Time of Troubles. The subject of the adventure is the tunnels connecting to to Tower of Ashaba that are rumored to connect to the underdark.

For as far back in time as the tales of history stretch, the area bordering what is now the Lands of Launewt has been a foreboding, practically impenetrable forest. When the lords who ruled the various borderlands united to form the Council of Launewt a century ago, the forest was in the same physical condition as it is now: thick, dark, and expansive, said to be so dense at the center that sunlight pervaded the foliage only on the brightest days.

THE NEXT MARCH WASN'T DUE FOR ANOTHER 189 YEARS. TRY TELLING THAT TO THE MODRONS! On a regular schedule, the Great Modron March spills out of Mechanus, and the lawful automatons files their way around the Great Ring. No one knows why they do it, but everyone stays out of their way - because when the modrons march, they'll walk right over a berk who doesn't know enough to move aside. But this March has started decades before it was supposed to begin, and that's even more of a mystery. Caught unprepared, the planes shudder under the modrons' collective footsteps - and even the modrons themselves seem a little out of sorts. The Great Modron March anthology features 11 adventures for characters ranging from 1st to 10th level, as well as new information about the modrons of Mechanus. Each adventure can be played separely or linked together to form an extended campaign. The modron procession touches every Outer Plane in turn - and it isn't always welcome. On their unswerving path, the clockwork creatures will destroy celestial towns, be attacked by evil knights intent on using modron parts in foul experiments, and lead characters onto the deadly plains of the Abyss and into the famous prime-material labyrinth of Undermountain. Without help, they'll be lost in the swirling chaos of Limbo or even fail to complete the March entirely. And along their route, every blood on the planes seeks the answer to the most important question: Why have the Modrons abandoned their normal, lawful schedule to march years before they're due?
