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.

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.

From The Magazine: "Every summer, Duke Hightower holds a competition quite different from the traditional jousting and archery tournaments held by similar lords of his station. The rules of his tournament change from year to year, and, to oversee the games, the duke has appointed two wizard brothers who help choose the setting and create the rules and challenges of the competition. This year the competition is called the “Owlbear Run,” an overland race that requires each participating team to escort a live owlbear from the town of Telvorn to the town of Milvorn. The teams will face a variety of challenges; some are devised by the wizards, others by the competing teams or their sponsors, and some occur entirely at random. All of these tests are in addition to the challenges inherent in motivating a temperamental owlbear. Fortune and fame await the first team to cross the finish line, and the local lords sponsoring the race are eager to enlist skilled champions for their causes." Pgs. 2-27

The sleepy village of Raven's Lake has a secret: A terrible god lives in the depths of the settlement's namesake. The citizens of Raven's Lake know that something lives in the lake. People who go out on the lake after dark go missing far too often and frequently turn up weeks later with no memory of where they've been. The local church of St. Cuthbert has been abandoned no fewer than seven times in the last two years, each time its lone cleric packing hastily and fleeing town without a word. Adventurers who come to Raven's Lake have a habit of vanishing forever. The truth is that something does indeed live in Raven's Lake but it is far from a deity. It's an exiled aboleth by the name of Zlorthishen. Pgs. 33-36

As the story goes, worshipers of Bahamut and worshipers of Gruumsh spent years warring. As the dead piled up, a Bahamut faithful crafted a weapon of devastating power. Most of the inventor’s peers balked at its use, but some felt it was justified. Those few who used the weapon were twisted into mad, dark beings by its corrupting power. The rest of Bahamut’s flock locked them and the weapon away in a dungeon prison. The dungeon and its terrible secret were long forgotten—until a group of rakshasas happened across the ancient tale. Now they seek the weapon for their own designs. Pgs. 132-137

Important: The adventure is 1e but it has monster conversion notes for D&D 4th edition The town of Highport, once a human community overlooking Wooly Bay from its perch on the northern coast of the Pomarj, fell prey to hordes of humanoids swarming out of the jungle-covered hills surrounding the settlement. Though the orcs, goblins, kobolds, ogres, and gnolls razed much of the place in their ferocious rampages, the smoldering ruins they left behind soon became a new kind of community, a place of trade between the humanoid “locals” and the unsavory human traders who have no compunction about doing business with them. Slaves are a commodity in ready supply in Highport’s market, since many pirates raid up and down the coast of the bay, putting fishing villages to the torch and filling their holds with captured refugees. Slavery has become a thriving business in the town, and rumors abound of a cartel of Slave Lords who run things from behind the scenes, filling their coffers in secret from the buying and selling of human chattel. The trade has become so prolific that the good folk to the north have grown tired of these depredations and decided to fight back. Forces of righteousness and honor have recently descended upon Highport, some openly and others in secret, in various attempts to destroy the machinations of the Slave Lords and abolish the abominable enterprise that has taken far too many loved ones from home and hearth. One such doughty servant of goodness is Mikaro Valasteen, a cleric of Trithereon. Mikaro slipped unnoticed past the crumbling walls of Highport with a single mission: to rescue and transport as many slaves to their freedom as possible. Mikaro and a handful of faithful assistants located a number of escaped slaves—as well as rescued a few more not sufficiently restrained and guarded—and shepherded them through the gates and beyond the reach of their humanoid tormentors, returning them to their lands and homes. This covert freedom brigade enjoyed remarkable success early on, since the servants of the Slave Lords were often lax in their vigilance and sloppy in their efforts to prevent loss of the “merchandise.” After one too many shipments never made its destination, the humanoids stepped up their security and the normal channels of escape from Highport closed to Mikaro and his team. He cannot risk exposure by smuggling the freed slaves through the gates as merchandise any longer, since shipments of goods are now regularly stopped and checked. No longer able to free the slaves in that manner, Mikaro began hiding his charges in an abandoned villa in a particularly rundown part of the town. Although they are safe for the moment, their numbers have grown unmanageable, and the priest fears it is only a matter of time before someone slips up and brings slavers to their doorstep. Ever more desperate to find a new means of escape from Highport, Mikaro has started work on a plan that is both daring and dangerous. He intends to use a series of old sewers coupled with natural caverns running beneath the town as an escape route to the sea beyond the walls. But he needs someone to clear out the creatures and pitfalls he knows lie within. Pgs. 2-27
