Once famed for its prosperous silver mines, the Mistlands are now a haunted realm of perpetual mist and endless ruins. A realm of ghosts and memories, few adventurers are brave enough to explore the rugged hills, for many who do are never seen again.

This supplement explores the history of the former realm of Silverdale, and presents rules for adventuring in the mist-wreathed lands, as well as over half a dozen new locales. The cult of Niht is explored in greater detail, along with the minor gods of sleep and concealment. Finally there are three new monsters, including the much-feared shadow dragon.
