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.

People from all over the world travel to the oracle of the dead, the Necromanteion, to commune with the spirits of the dead. Following a ritualistic preparaton of the body and the mind, a "Seeker", as they are called, enters the Adyton, and with the help of the Prophet comes in contact with spirits. Who would your characters talk to if they found themselves in the Necromanteion? Before you can answer that, you must first save it from a demonic invasion! With the temple in chaos, and foul fiends everywhere, will our adventurers be able to save the Necromanteion?

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!

The Dreaming Caldera involves the players infiltrating a volcano teeming with monsters that are intent on constructing a chaos god. The players must navigate through the hostile environment, disrupt the monstrous activities, and ultimately prevent a catastrophic event. 27 keyed locations Written for the Old-School Essentials (OSE) rule system

Long hidden away in remote vaults and guarded by powerful wards, the ancient Seven Swords of Sin have been stolen and brought together again for a terrible cause. Seven Swords of Sin is a lethal adventure that pits players against a vile enchantress, Tirana, in a trap-laden and monster-guarded dungeon. Only the brave (and perhaps foolish) can survive Tirana's lair and rescue the fabled Seven Swords of Sin from her heinous plot to unlock their deadly powers.

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.

"Mysterious Ways" is a D&D adventure set in the Holy Land (Israel and Jordan) during the time of the Crusades (1114 A.D.) in an alternate-Earth setting. This is a world where the portals to otherworldly realms, particularly the Lower Planes, are closed--sealed shut by the power of the True Cross, a holy relic sought by evil thieves who would see the gates to the Lower Planes flung open. Magic exists in this alternate world, but it is less prevalent than in other D&D campaign settings. This paucity of magic serves the core of the adventure's storyline and should be preserved, if possible. This adventure is designed for a party of four 7th-level player characters (PCs). It is recommended that the party include at least one lawful cleric or paladin. Consult the "Adapting the Adventure" sidebar for ways to incorporate the adventure into generic D&D campaigns and modify it for higher or lower levels of play.

East of Beregost, nestled in the outskirts of the Wood of Sharp Teeth, Durlag’s Tower has intrigued and yet stymied adventurers for decades. Stuffed full of mechanical traps and arcane wards, and rumored to be inhabited by fiends, very few have managed to extract any REAL treasure from the former home of Durlag Trollkiller. However, a powerful item in the ancient fight against the giants is said to be housed there, and the cloud giant Baron Rajiram has committed significant resources toward recovering it. After a pleasant tea in her garden, SEER calls upon you to beat him there and put a stop to his efforts! Continued in Durlag's Tomb.

"Investigate a mystical valley where stones can speak and monsters roam." "The Singing Stones" is a wilderness, point-crawl adventure for characters levels 3-5. It is set in a mystical valley known as Opera Valley, which is filled with sentient, speaking stones. It emphasizes exploration, interaction with unique environmental features, and solving mysteries through dialogue and puzzle-solving rather than straightforward combat. 23 keyed locations Written for the Old-School Essentials (OSE) rule system

The yuan-ti anathema, Hessatali, calls out to his yuan-ti faithful from his prison in the Abyss. His network of vipers has uncovered the ruins of ancient Ss’tatha’lass and the Fane of Hessatali, a fountain of pure venom that will return the demi-god to life. Above the buried ruins of Ss’tatha’lass, yuan-ti agents have moved to control the politics of Scornubel. The characters fall into a complex yuan-ti plot that spans the breadth of the realm, pits the heroes against the forces of the Abyss, and explores the culture of the yuan-ti.

While investigating rumors of a dangerous blue dragon wreaking havoc in the deep desert, the heroes tumble under the sands into the magically sealed dome of an ancient palace. 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. But the dome is weak because it has been assaulted by the mythical storm demon Azi Dahaka and his trapped minions, evil creatures that were sealed under the magical dome to keep them from ravaging an unsuspecting world.

The door to the Abyss can be opened with good intentions. An act of mercy released a creature of unspeakable evil. Now, only you have a chance to stop it. A vrock has been trapped inside a stone circle outside the village of Sundown. This stone circle remained untouched for thousands of years, until an unwitting mage decided to depetrify one of the standing stones that he mistakenly thought was a helpless farmer. This released the vrock, who killed the mage and has been trying to regain enough power to plane shift back to its home. This module primarily is based on investigation and problem solving, with a final fight with the vrock at the end. Roleplaying should be emphasized. The town of Sundown is fleshed out with NPCs and stores for player exploration. Pgs. 4-16

Deep in the wooded wilderness, the village of Grimmsgate is an outpost town on a seldom-traveled trail, right at the edge of nowhere. The village’s half-ruined temple of Law, dilapidated inn, drunken blacksmith, exiled trader and a few fur-trappers are enough to keep the bloody-minded denizens of the dark forest at bay, but nobody really expects the village to still be there in another ten years. The woods have become too dangerous for the trappers who once caught animals for fur, and merchants no longer travel the poorly-maintained road. What great evil and what fabulous treasures are to be found in these lands? A brave band of adventurers might make their fortunes here. Or perhaps they might never return… Grimmsgate is an introductory adventure for the Swords & Wizardry tabletop roleplaying game. The Swords & Wizardry rules are needed to play this adventure.

The characters begin by attempting to stop giant raids that have become prolific. They find out that the giant alliance is caused by the drow. They then descend into the Underdark in order to find the drow and stop their sinister plan. TSR 9179

A Conspiracy of Doors is a Dungeons & Dragons adventure for five player characters of 11th level. It can serve as an introduction to Sigil, the City of Doors, as well as a group of adventurers' first taste of action at the paragon tier.

Nearly 100 years ago, Lord Eriador wrested the lands from the hands of evil and began a reign of unsurpassed courage, wisdom, and might that lasted over three centuries. One day this great man of valor was called onward to continue his battle for freedom and goodness on a higher plane of existence. Leaving the responsibilities of rulership to his faithful overseer, he donned his magical shield, helm, and sword and traveled to the Holy Maountain of Anduin to meet his destiny. Eriador left the overseer with this solemn promise: if there ever arose a time of great need, he would answer a summons from the Mountain of Anduin to come back to vanquish any evil that dared to oppress his people. It is now the reign of the third overseer. For years now, an evil mage has been plaguing the land by sending forth hordes of evil humanoid minions to oppress the people. The overseer has been forced to pay tribute to the mage to protect his people. Life has become nearly unbearable for his subjects. It has been over five years since the mage desecrated the holy mountain by placing foul creatures in its depths to guard against the possibility of the people seeking help from their nearly forgotten champion. A fortnight ago, your party was gathered in a secret council chamber to meet with the overseer himself. You felt a spark of hope for the people of this land as the overseer told the legendary tale of Eriador. He gave you the equipment you need and charged your party with the task of venturing into the heart of the now monster-infested Mountain of Anduin to call back the people's great hero, Eriador the Paladin. Although the three parties sent before you had not returned, ridding the of the land of the mage seemed worth any risk, and you eagerly set out on your quest. Now, standing before the defiled mountain, you wonder if perhaps you were too hasty.

The characters have finally escaped from the maze and returned to complete the mission they originally started-they must infiltrate the tower of King Ovar and end his evil reign. Will the characters discover the secrets of the missing queen and the wizard Zayene's influence? Or will they perish in dragon fire?

The first part of the Dreams of Red Wizards adventure path originally published for the D&D NEXT Playtest. Following the events Ghosts of Dragonspear Castle, a new set of adventurer's will see some of the repercussions of that adventure. This adventure is intended to be continued in the Dead in Thay adventure (Note that they Dead in Thay 5e adventure featured in Tales from the Yawning Portal is missing a significant portion of interlude that links Scourge of the Sword Coast to the events within the Doomvault). The adventurers arrive when Daggerford is crowded with refugees from outlying lands. Goblins, gnolls, and orcs have been raiding the countryside. Now, food is scarce and tension is high. Blame for a theft has fallen on the refugees, and the Duke of Daggerford has forbidden more of the displaced from coming into town. After overcoming difficulties to enter Daggerford, the characters learn more about the raids. As they fight against the humanoids and delve deeper in the darkness that encircles Daggerford, the characters learn of Bloodgate Keep. After a final fiendish ambush, they’re ready to confront the real threat to the area. DM Note: This adventure points the adventurers strongly towards Bloodgate Keep but that location does not appear until the Dead in Thay adventure; at several points the party may feel drawn to explore that location rather than continue their investigations around Daggerford. However, since Bloodgate Keep is only eluded to as a source of great evil power, it can serve to easily segue to an entirely different adventure path. As a NEXT Playtest adventure, Scourge of the Sword Coast uses milestone leveling and the included stat blocks for creatures do not necessarily match or even appear in the 5e Monster Manual, nor do they have XP values or challenge ratings. In some places it will reference rules used in the Playtest but dropped or changed in the 5e release, these are unlikely to substantially impact gampley with 5e rules.
