Anauroch: The Empire of Shade

Anauroch: The Empire of Shade (also known as Anauroch: The Sundering of the World in advertising but the title was changed before publication) is an adventure module set in the Forgotten Realms using the 3.5-edition ruleset of Dungeons & Dragons. "Anauroch: The Empire of Shade is the final part of a three-part series of 160-page hardcover super-adventures set in the Forgotten Realms campaign setting. It can also be easily played as a stand-alone high-level adventure. In addition to encounters, this book contains detailed source material on the land of Anauroch, home of ancient Netherese ruins and the Empire of Shade."

Summary
Anauroch: The Empire of Shade offers PCs the opportunity to at last confront the ambitious machinations of the Princes of Shade, who have the power of Karsus himself within their grasp. The PCs must sift through history to determine what threat looms over the land, and then overcome the challenge of trekking through a hostile environment without the comfort of the Weave and its magic to aid them. To stop the shades from advancing their ambitions against the rest of the world, the characters must penetrate the very heart of the Empire of Shadow. Only by scattering the pages of the Nether Scrolls can they put a halt to the Shadovar scheme and prevent Shar from shattering magic forever.
