For over a thousand years the things that lurk beneath the waters, skulk in the darkness and lie hungrily in dank crypts have been patient, while all around them men and monsters bicker amongst themselves, bold enough to traverse the dark caverns' depths but afraid or perhaps wise enough to leave the forgotten vaults and hidden passages alone. Beneath the lost ruins of ancient Thracia lie the vast caverns of a once great civilization. While a death cult rules the surface, the Minotaur King and his beast men lurk fall below. Descend even deeper into the darkness and discover a lost and arcane world that waits for those brave enough to enter! Necromancer Games and Judges Guild have teamed up to expand and update the classic module Coverns of Thracia for 3.5. Designed for characters of 3rd to 8th level and higher, the Caverns of Thracia is a mini-campaign setting that presents intricate plots and exciting adventures.

In the city of Waterdeep rests a tavern called the Yawning Portal, named after the gaping pit in its common room. At the bottom of this crumbling shaft is a labyrinthine dungeon shunned by all but the most daring adventurers. Known as Undermountain, this dungeon is the domain of the mad wizard Halaster Blackcloak. Long has the Mad Mage dwelt in these forlorn depths, seeding his lair with monsters, traps, and mysteries—to what end is a constant source of speculation and concern. This adventure picks up where Waterdeep: Dragon Heist leaves off, taking characters of 5th level or higher all the way to 20th level should they explore the entirety of Halaster’s home. Twenty-three levels of Undermountain are detailed herein, along with the subterranean refuge of Skullport. Treasures and secrets abound, but tread with care!

Part megadungeon, part underground expedition, Operation Unfathomable serves as both a one-shot adventure and a campaign framework. PCs are (optionally) drafted at swordpoint to recover the Nul Rod, a priceless artifact that was recently lost in a local prince's foolhardy attempt to destroy the Chaos Gods of the Underworld. The PCs have been drafted as an expendable set of pawns to venture into the vast and bewildering Underworld and retrieve the Nul Rod. With the Underworld's innumerable beasties being on high alert after the prince's expedition, the PCs must sneak through the incredibly dangerous Underworld. Fighting is not as important as stealth, fast-talking, and running away rapidly. This is the expansion from Sholtis's original Operation Unfathomable, released in Knockspell #5 (2011).

For decades, the tiny village of Ravenmoor has existed quietly on the upper reaches of the Lampblack River. Linked to the outside world only by an overgrown, mostly forgotten trail, the villagers are comfortable with their isolation. Certainly, the lack of a village inn, the oppressive humidity, and the bug-infested moors and swamps that surround the village do little to encourage visitors. When a clerk in the city of Magnimar discovers that, due to a clerical error, the village of Ravenmoor hasn’t paid taxes in years, a tax collector is sent to the distant community to settle accounts with its mayor. When the tax collector fails to return, however, a group of adventurers must travel to the town during its Founders’ Feast celebration to investigate his disappearance.

The Dread tunnels of Ruxbar were created by a cult of a lesser evil deity of the giant pantheon, known as Jargain to serve as a planar gate in hope of bringing chaos and destruction to the natural order of the world and power to the one who would control the gate. Ruxabar was the high cultist who completed the ritual but to his surprise nothing of what he expected came through the gate. Plague creatures, toxic gases and vapors, diseases of all kinds and decay lay quick waste to him and his cult. For some time the gate remained open and the settlements nearby were afflicted with diseases never seen before. The nearby town of Stagwood was quickly abandoned due to the plague. Rumor has it that the gods have weakened the gate and the cult has been destroyed. The remaining villages that managed to somewhat resist the plague are now hiring brave adventurers to venture into the tunnels and close the planar gate for good! Are you capable enough of surviving the horrors that reside in the Dreaded Tunnels of Ruxabar? Published by Mistfactor Press

In this prelude to the full Princes of the Apocalypse campaign book, adventurers face off against the influence of Elemental Cultists in the hills and canyons of the Dessarin Valley. The four mini-adventures within are only tangentially related to each-other, and instead serve as starting points and hooks for the plots of the complete Princes of the Apocalypse Campaign. Players start in the well-described town of Red Larch; first investigating a local necromancer, then uncovering cult influences within the town, and finally heading off to infiltrate or do battle with two small elemental cultist strongholds. All parts of this adventure can serve as great places to seed hooks for other campaigns.

The ancient world of Harth withers beneath its dying sun…but it’s not dead yet. Welcome to the strange and dangerous city of Carcassay, huddled below the skeleton of a titan rat, sprawling above the ruins of countless dead civilizations. This is where folk come to find wealth, power, revenge, secrets, oblivion… and everything in between. Carcassay is a sandbox city adventure. There are many locations to explore in, around, and under the city. Players can explore any place at any time, and may radically reshape the city’s politics, economy, religions, and physical existence. There are standard dungeons stacked under the city, and GMs are encouraged to keep adding more dungeons… all the way down. Tone. It leans more toward low fantasy or sword-and-sorcery. Most shops look like real shops. Most people look like real people. But strange and horrible things lurk everywhere as soon as you start to scratch the surface. This is my Lankhmar. Carcassay is a vast, bizarre city. It has over 100 locations where you can meet Chaos cultists, Lawful knights, retired adventurers, shopkeepers, brewers, musicians, artists, scientists, hermits, royalty, beggars, doctors, space vampires, eldritch horrors, machine priests, crab colonists, mushroom farmers, mummies, assassins, and diplomats from distant lands… and the moon. And every one of them has goods or services to sell, and a quest (or three) to offer. What sort of quests? Fetch a relic, assassinate a rival, find a relative, steal a soul, implant an agent, cure a disease, stop a riot, solve a murder that hasn’t happened yet, hunt a thief, locate a shrine… the list goes on. And for every Quest, there is a specific Reward: money, weapons, relics, Chaos mutations, exclusive memberships, information, Angelic miracles… the list goes on. This is a place where you can make a lot of money, but also where you can spend that money on interesting goods and services. Factions? We have a few. Seven Chaos cults, five knightly orders, two mercenary companies, four wealthy families, six (seven!) Corpse Lords, foreign diplomats, rival innkeepers, rival tavern owners, plus all the dungeon-delving gangs currently mucking about underground. When you grow weary of all the adventures at ground level, there are three classic dungeons buried under the city to explore. This book contains months (if not years) of campaigning. Enjoy the Chaos.
