After exploring the dreaded Castle Ravenloft, a surprise ”attraction” at the traveling Carnival, and facing off against the legendary vampire lord Strahd von Zarovich himself, the Wayfinders were shocked to discover that certain nightmares were becoming realities thanks to the involvement of a dreamwalker. As the riddles deepen, the party must venture deeper into the mystical Litwick Market for the truth that connects the Nightmare Man to the larger plots involving the Domains of Dread and Master Mirror, and their adventures might even take them to the depths of the enigmatic Plane of Dreams. But the Carnival has just arrived in a new land called Dementlieu, a place of intrigue, decadent delusions, and more mysterious murders. The heroes must find the thread that binds these events and places together, lest it all finally unravel and reality itself breaks apart… for good.
