A genius inventor - Anthony Karstark, founder of the "Karstark Inventions", has recently reached a new level of reclusiveness, when he stopped showing up at his company events. A concerned friend and employee, Holly Amberfell, hires an adventuring party, to figure out what happened to him. As adventurers enter and explore the quarantined manor of the great inventor, they have to deal with his mechanic inventions, figure out minor mysteries of past and present, and finally - face Anthony himself, changed by a strange disease into a Slaad-spawn. Guesting at Artifice Manor is an 8-10 hours long mystery and exploration adventure, that should roughly take two playing sessions (or can be squished into one - suggestions on how to do it are inside the book!). It is optimized for 4 to 5 characters of 8-10 levels. This adventure can be used to kick-off a campaign, exploring the origins and history of Slaads.

None know from where the Heresiarch first came, but all remember the night that it did. It rode down from the bleeding stars on a great serpent, hurling bolts of obsidian lightning that shattered the monuments and capitols of every nation. Its infernal army swept aside the defenses of the mortal empires in a single hour, decimating legions once thought to be the invincible fist of humanity's god-kings. Faceless priests - each bearing the symbol of the trident - drifted through the fallen cities and scorched villages on a frigid wind, and when they rose to greet the huddled men and women ringed by their festering, bloated dead, they spoke a single, simple offer: worship the Heresiarch or die. Thousands of crusaders fell tonight so that you might be given this chance. In a last stand that, for the first time, united all of the empires of humanity as brothers and sisters, a way was cleared into an infernal stronghold said to contain a gate to the Heresiarch’s fane. All is silent save for the clangor of distant battle. Surrounded by grim-faced knights and teary-eyed peasants – their hands clasped in desperate hope – you step through the glowing, churning doorway, knowing there will be no help and likely no return.

A slaver gang known as the Bloodreavers are terrorizing the countryside from their base deep in the labyrinth under Thunderspire Mountain. But these slavers are only the symptom of a larger threat in the bowels of Thunderspire.

Many centuries ago, the dwarven kingdom of Sarphil stretched out across the Galena Mountains east of the Moonsea. They dug for the precious metals hidden beneath the rocky terrain, and they established numerous cities and settlements to aid in their excavation and manufacturing efforts. This was during the early days of Myth Drannor, the elven kingdom in the forest of Cormanthor, and the dwarves and elves initially clashed as each sought resources and expanded their territories. Myth Drannor and Sarphil eventually settled their differences, and many dwarves moved into the elven city to offer their services and expand their knowledge. In the Galena Mountains, Sarphil continued to flourish. Unfortunately, these days of prosperity did not last long. The last great king of Sarphil was lost in the dwarven city of Mount Throndor, beneath the mountain peak of the same name, and Sarphil withered under bitter clan disputes since no single family could claim legitimate lineage over the fragmented kingdom. What happened under Mount Throndor has been a mystery for thousands of years. Many attempts have been made to reclaim the lost riches and legacy of the last Sarphilan king, but powerful wards have prevented intrusion under the mountain, wards erected by the dwarves of Sarphil. Were the wards built to keep outsiders from intruding – or to keep something inside from escaping? An enterprising dwarven leader wants to find out, but she is going to need some help from a band of heroes. Horrors of Mount Throndor is a Dungeons & Dragons adventure of exploration, darkness, and terror featuring a lost dwarven city overrun by forces from the Far Realm and the journey to cleanse it once and for all. The adventure is designed for a group of 11th-level characters, and successful completion of the adventure should put the characters at 16th level. Here There Be Monsters Mount Throndor has become infested with madness from the Far Realm. During their journey to penetrate the ward and through the city itself, the characters are going to face gibbering horrors, unpredictable slaadi, fanatic stone giant cultists, degenerate star spawn horrors, mutant derro, undead dwarves, and countless golems. The ancient breweries of Mount Throndor have produced alementals who slither in the darkness, and a great dwarven war juggernaut named Big Hans stomps through the city. Legendary Villains and Epic Moments Though it has been sealed, Mount Throndor is not empty. The characters have opportunities to meet, interact with, and (likely at least) combat against powerful foes within the legendary dwarf city. A dwarf lich, a Far Realm spider goddess, an iron-encased demilich, and a melted flesh derro warlock monstrosity all await, along with a mind-bending force - Great Cthulhu! The characters have a chance to face an avatar of Great Cthulhu in the dwarven depths in the final confrontation of the adventure to free Mount Throndor and rid Faerun of a Far Realm invasion! An Adventure of Exploration Mount Throndor is a big, sprawling complex, a dwarven city with two major strongholds, a bridge system spanning a massive underground lake, and a deep mining complex. The scale is difficult to grasp and convey. Previous examples of adventures featuring these elements have included maps - usually lots of them, great spawling maps connected at ends to make huge subterranean dungeons. It is the classic image of a D&D dungeon crawl, and the map is a key component to its visualization. However, in this adventure, the maps are handled differently. There are certain areas, ususally outside the dwarven city itself, that include maps that are suitable for use at the game table, either in theater of the mind style or grid-and-miniatures. Mount Throndor itself is presented with an abstract map, and exploring it utilizes the exploration procedure outlined in Appendix A. Characters traverse the huge subterranean system using this abstract system, and during their travels they are going to run into random encounters and sites with more interesting and complex encounters.

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 town of Whitehaven is beset with undead. The townsfolk are quick to blame the Witch of Whitehaven, who lives nearby with her partner in the Surbrin Hills.

“Gorgoldand’s Gauntlet” takes place in a cave network in the side of a cliff overlooking a lake and can be inserted easily into any campaign. Gorgoldand’s Gauntlet is a site-based adventure with a pre-dominance of puzzles and traps. The PCs discover a map leading to the Gauntlet and explore it looking for treasure. They test their strength and wits against various traps and puzzles created by a gold dragon who converted a cave network into a proving ground to surreptitiously test the abilities of local adventuring bands. If they make it all the way to the end of the Gauntlet, they’ll have the chance to fight a dragon construct made of the dungeon's treasure hoard and have the chance to gain access to a magic item that can have a significant impact on their adventuring careers. Pgs. 39-51

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.

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 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.
