The orb spoke to him with flattery and advice. As he became reliant on the orb, its power over him extended, bending him to its will and taking control. It used him to further its agenda: destruction of the dwarven race and restoration of the duergar! Claiming to be acting on Odin's behalf, Ulvmard lead the Northmen to rise up against the dwarves, and ordered raids to pillage the southern kingdoms for the materials he would need to construct a colossal iron warrior to defeat the dwarves.

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.

Imprisoned in the first layer of Hell a group of unfortunate adventurers must find their way out amidst the chaos of the Blood War. Will they escape before the Lord of the Keep finds them? Well, only time will tell...
