Enter the ancient and corrupt city of Tyr, whose tyrannical sorcerer king has ruled for a millennium. As you wander the city, from the wreck of the Elven warrens to the sanguine splendor of the arena, you realize that the citizens of Tyr thirst less for water than they do for freedom. Now, after a century of slave labor, sorcerer king Kalak's great ziggurat nears completion. He has promised the city a grand celebration when the monument is done, complete with the most brutal arena spectacle in Tyr's long history. Rumors abound as to the nature of the spectacle: some believe it will bring with it the longed for manumission of countless slaves: others fear the annihilation of Tyr and her people as a sacrifice to Kalak's hunger for power; and a secret few believe it will be a day of revolution - a day of freedom. The adventure that introduces the Dark Sun setting as well as part of its metaplot. The adventure starts with the PCs being enslaved and forced to work on Tyr's ziggurat, where they make various connections that can affect things both in this adventure and the next in the series (Road to Urik).

Under raging stormclouds, a lone figure stands silhouetted against the ancient walls of castle Ravenloft. Count Strahd von Zarovich stares down a sheer cliff at the village below. A cold, bitter wind spins dead leaves around him, billowing his cape in the darkness. Lightning splits the clouds overhead, casting stark white light across him.

Fas below, yet not beyond his keen eyesight, a party of adventurers has just entered his domain. Strahd's face forms a twisted smile as his dark plan unfolds. He knew they were coming, and he knows why they came, all according to his plan. He, the master of Ravenloft, will attend to them.
