Conan of Cimmeria has returned north to find the area under siege from a supernatural threat – known in the surrounding wilderness as the "Tribe of the Lost." Aided by a battle-ready Pictish scout named Brissa, the two warriors have hacked their way through trails of the undead who seemingly answer to an unseen master. Now, as they reach the end of carnage's path, Conan and Brissa have encountered a mysterious tower of black stone – the possible source of the horrors that have led them this far. But now a question looms larger than the spire itself... how much further will they need to go?
