With the rise of Tiamat threatening to destroy the world, the undead masters of Thay have approached the Council of Waterdeep to discuss the possibility of an alliance. But the Dragon Queen has agents everywhere, even in a remote keep on the Thayan frontier. A vampire noblewoman has been killed, and the characters are the prime suspects. To clear their names, they must find the real killer, and learn how even the undead may die… Murder in Thay is a 4-6 hour Dungeons & Dragons adventure for characters of levels 13-14, for use as an expansion of the "Mission to Thay" chapter in Tyranny of Dragons or as a standalone module. This publication comes with a map pack, a new magic item (the pyx of soul capture), and monster and NPC stat blocks, including two new creatures, the fearsome dread centurion and the not so fearsome undead cat!
