Conan of Cimmeria has seen much in years as a reaver and mercenary, yet still some things remain shrouded in dark mystery. On his travels, Conan has come in contact with a malevolent force bound in enigmatic Black Stone, a power whose influence and malice has followed him through both the Hyborian Age and the swirling mists of time. Now, at an Aquilonian outpost on the edge of the Pictish wilderness, the Cimmerian encounters that familiar dark power once more upon the breast of a slain Pict: a mysterious eye Sigil.
But Conan is not alone in his discovery of the sigil. Across time and space, the sign is seen and its presence felt by other Heroes of Men. In each instance, and in their own ways, our heroes will be forever marked by the Black Stone...
