The Time of the Dark
Night after night, Gil found herself dreaming of an impossible city where alien horrors warmed from underground lairs of darkness to destroy mankind and all the works of men. But when the wizard Ingold Inglorion crossed the Void to ask sanctuary for the last Prince of Dar, he learned her dreams had been true visions of a strange reality. 

On Ingold's world, the monstrous Dark had been mere legends for 3,000 years, But now, for unknown reasons, they were ravening savagely across the land, and there was no escape from their fowl powers and insatiable hungers. 

Attempting to help Ingold, Gil and Rudy, a young drifter, were drawn into the nightmare world of the Dark. There they had to remain-unless they could solve the mystery of the Dark. 

Then, before they could realize their fate, the Dark struck!
