An ancient cave, defended by ancient death traps and weird arcane seals conceals the antediluvian vault of an archlich whose reign predates recorded history. Undisturbed for untold eons, the vault now stirs thanks to the machinations of cultists who have meddled with secrets best left undisturbed... This module sends the heroes to an ancient cave occupied by cultists dedicated to the Mists of Madness. Defended by ancient death traps and weird arcane seals, the caves conceal an antediluvian vault, the resting place of an archlich whose reign predates recorded history in the Known Realms. Undisturbed for untold eons, now the machinations of the cultists and their eladrin master threaten to awaken the archlich, to dire ends that none can predict.

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!

Conquest, not beauty, is in the eyes of this beholder. A promise of adventure and riches, with a hint of total annihilation. The party should also have several powerful magical items, since the challenge that it faces is great. The geographical background and the local population are left vague so that the adventure can fit any campaign setting. Pgs. 39-44

What is the Lost Lands? The Lost Lands is the home campaign world of Necromancer Game's and Frog God Game's own Bill Webb. This campaign has been continuously running since 1977. Many of the adventures published by Necromancer Games and Frog God Games are directly inspired by this campaign. They have evolved over the decades, and more material continues to flow from it as the dice keep rolling. Sages and wizards of legend speak of the Lost Lands—many of the players who have lived and died in Bill's campaign over the years now have a place in history (in the books). Frac Cher the dwarf, Flail the Great, Bannor the Paladin, Speigle the Mage, and Helman the Halfling are well known to the fans of Bill's work. This is the game world, and these are the adventures in which the players of these famous characters lived and died. Hundreds of players over the past 35 years have experienced the thrills and terrors of this world. The Sword of Air is the centerpiece of the Lost Lands. Currently, this epic tome consists of several parts: 1. The Hel’s Temple Dungeon—kind of like Tomb of Horrors on crack. This six-level, trap-and-puzzle infested dungeon formed the basis of Bill's game through his high school and college years. Clark Peterson’s very own Bannor the Paladin spent several real life months in the place, and, sadly, finished the objective. This is where the fragments of the fabled Sword of Air can be found…perhaps. 2. The Wilderness of the Lost Lands extending to the humanoid-infested Deepfells Mountains and providing detail about the nearby Wizard’s Wall. This so-called “wall” was raised by the archmages Margon and Alycthron harnessing the Spirit of the Stoneheart Mountains to raise the land itself, creating a massive escarpment to block invaders from the Haunted Steppes. These archmages are actual player characters from the early 1980s who live on in the legends of the Lost Lands. Over 70 unique encounter areas are detailed, and each one is a mini-adventure in itself. New wilderness areas may be added based on bonus goals described below! 3. The Ruined City of Tsen. Legend has it the city was destroyed by a falling meteor. This place forms an aboveground dungeon area the size of a city, with over 100 detailed encounter areas. It’s a very dark place…even at noon. 4. The Wizard’s Feud—This campaign-style adventure pits the players in a long-running series of intrigues and battles between two archmages. Which side will they take? Their actions all play into the overall quest, and could well determine which side wins. Law and Chaos are not always what they seem, and if the wrong decisions are made, the entire ordeal could fail. Remember, one of the wizards WANTS Tsathogga to win. 5. New monsters, new demons, new spells, and new rules for various aspects of play. 6. The Tower of Bells. This dungeon is the result of the workshop Bill ran at PaizoCon 2013, where the participants assisted him in building an old-school dungeon. Visit the tower and discover the secrets of the “artist” within. Beware: those entering may never come out!

For more than a hundred years, the demon-infested Worldwound has warred against humanity, its Abyssal armies clashing with crusaders, barbarians, mercenaries, and heroes along the border of lost Sarkoris. But when one of the magical wardstones that helps hedge the demons into their savage realm is sabotaged, the crusader city of Kenabres is attacked and devastated by the demonic hordes. Can a small band of heroes destined for mythic greatness survive long enough to hold back the forces of chaos and evil until help arrives, or will they become the latest in a long line of victims slaughtered by Deskari, the demon lord of the Locust Host?

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 Cult of the Dragon, along with its dragon allies and the Red Wizards of Thay, seek to bring Tiamat from her prison in the Nine Hells to Faerûn. To this end, they are sweeping from town to town, laying waste to all those who oppose them and gathering a hoard of riches for their dread queen. Continued in The Rise of Tiamat.

Punjar: wide-eyed madmen stalk the streets pronouncing the end of days, mail-clad priests crush the skulls of heathens underfoot, and timorous virgins are offered up in sacrifice within sooty temples. But even the greatest of shining temples and the strangest of mystery cults don’t dare to challenge the terrifying finality of Death. Until now. In Blades Against Death, the adventurers cross between the realms of the living and the dead, and wager their souls in a desperate bid to steal a soul from Death’s hoary grasp. To win over the God of Dooms, you must be the most daring, stalwart and cunning and – when all else fails – willing to test your blades against Death! A mid-level adventure for the Dungeon Crawl Classics Role Playing Game, Blades against Death offers characters a once in a lifetime escapade. Those that return from the Realms of the Dead will have earned the true title of adventurer, while those that fail will spend eternity in Death’s service.

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.

Death Is in the Cards The remnants of the Ebon Fold are cutting a deadly path through the Falkovian countryside, draining travelers of their life force and leaving withered corpses in their wake. Hot on their trail you come across the sole survivor of one of these deadly attacks, a young vistani man with an extraordinary skill for fortune-telling.

These three organizations working together bodes ill for the residents of Nartok. ... And Schemes Within Infernal Schemes Great amounts of life energy are being collected for some foul purpose, although no one seems to know what exactly it is. The tarokka cards provide only mysterious glimpses of the future - a future in which a powerful evil sweeps the land and Death walks the world. Can you discover the truth of what is happening in the temple in time to avert the disaster predicted by the cards? Death Ascendant is a full-length adventure that can be run as a stand-alone scenario or as the second part in the Grim Harvest series. It contains a 64-page adventure booklet plus a full-color poster map detailing the Temple of the Eternal Order. TSR 9526

The lost city of Archaia - an ancient ruin sunken into the earth - lies deep in the badlands. In recent years, caravans from Eastdale have come under attack from orcs, goblins, and worse. Some say these blood-thirsty warbands have made lairs in the deep caves and ruins. Sill others say the ancient halls are filled with magnificent treasures left by the Archaians. Are you brave (or foolish) enough to delve The Forbidden Caverns of Archaia? The Forbidden Caverns of Archaia (FCoA) is a 296-page classic megadungeon for use with any old school fantasy role-playing game.

The Forbidden Caverns of Archaia will keep your players on their toes and your campaign going strong for years. FCoA is brought to you by the Old School Renaissance (so don’t forget your 10’ pole).

This Adventure is based on the web comic series, Table Titans. It is set in the same village that part of the comic takes place in, however the path of the adventure does not follow the story line set in the comics. There are familiar elements that are a wink and a nod to fans of the comic, but it is a unique story. The adventure is set around the village of Haverford, currently beset by an unknown [i]Terror[/i] that has resulted in many many deaths in the surrounding forest. The adventures have arrived at this once peaceful hamlet and if they discover the source of the [i]Terror[/i] plaguing the region they will be handsomely rewarded. The Terror of Haverford is a starter adventure. Characters will advance from level 1 to 4 if completed. This adventure has both social and combat encounters, as well as combat encounters that can be solved socially. If characters aren't thorough in their investigations they will be taken by surprise by what lies ahead.

The PCs answer a call for heroes by the Church of Traladara, asking for help in finding an ancient relic- the Shield of Halav. This is located in a lost temple, and the PCs must locate this temple, and brave its dangers to recover the shield before two competing teams from other churches find it first. Part one involves setting up the adventure, doing research, following clues, and discovering the site of the lost temple. Part two; once the site is known (ruins under a modern town) the heroes must travel there and find the entrance. Part three is braving the lost temple, filled with traps, puzzles, and other dangers, to find the missing shield, and then culminating in a climatic showdown with the completing teams.

A nest of vampires has claimed a dark forest and the surrounding human towns as its domain. Some of the local residents revere the vampires and serve as daylight guardians and spies. However, most of the townsfolk live in a state of dread. Those townsfolk have finally scavenged enough valuables to hire a band of adventurers to destroy the nest. Pgs. 66-71

In the Anauroch desert, darkness is growing. The followers of the Vile Spore Goddess Zuggtmoy have stolen the dreams of the Bedine Seeress Deja, trapping them in an eldritch artifact. Unless her dreams are returned, the Seeress will descend into madness, and her people along with her.

"More than five hundred years ago, clans of dwarves and gnomes made an agreement known as the Phandelver’s Pact, by which they would share a rich mine in a wondrous cavern known as Wave Echo Cave. In addition to its mineral wealth, the mine contained great magical power. Human spellcasters allied themselves with the dwarves and gnomes to channel and bind that energy into a great forge (called the Forge of Spells), where magic items could be crafted. Times were good, and the nearby human town of Phandalin (pronounced fan-duh-lin) prospered as well. But then disaster struck when orcs swept through the North and laid waste to all in their path. A powerful force of orcs reinforced by evil mercenary wizards attacked wave echo cave to seize its riches and magic treasures. Human wizards fought alongside their dwarf and gnome allies to defend the Forge of Spells, and the ensuing spell battle destroyed much of the cavern. Few survived the cave-ins and tremors, and the location of Wave Echo Cave was lost. For centuries, rumours of buried riches have attracted treasure seekers and opportunists to the area around Phandalin, but no one has ever succeeded in locating the lost mine. In recent years, people have resettled the area. Phandalin is now a rough-and-tumble frontier town. More important, the Rockseeker brothers - a trio of dwarves - have discovered the entrance to Wave Echo Cave, and they intend to reopen the mines. Unfortunately for the Rockseekers, they are not the only ones interested in Wave Echo Cave. A mysterious villain known as the Black Spider controls a network of bandit gangs and goblin tribes in the area, and his agents have followed the Rockseekers to their prize. Now the Black Spider wants Wave Echo Cave for himself, and he is taking steps to make sure no one else knows where it is." Extra Info from AL.com users: by @marcellarius. "There are a variety of locations in this adventure: the town of Phandalin, a gang hideout, a ruined keep in the forest, a destroyed village, and Wave Echo Cave (a dungeon crawl). The adventure is written in a sandbox style and relies on the players to choose their path. Phandalin offers several side-quests which could serve as hooks for continuing adventures. The premade characters have ties in their backgrounds to NPCs and locations. If you're not using these you'll need to consider other ways to introduce key NPCs."

The mine has been known as Tessount’s Folly for years, due to it producing nothing of value. Now Valmour, the youngest son of the mine’s late owner, has inherited the mine...and found something he should have left buried. Pgs. 56-81

Missing relics and a mysterious well. These are the things that have drawn your party to this idyllic region of the land. Why would someone take sacred objects, what do they have to do with each other…and why does the trail lead to a well in the middle of a lake?

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.

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).
