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.
