A girl stumbles across the moors, death hard on her heels. To her saviours, she speaks of Calignius - a smog-shrouded mining town deep in the mountains that has been gripped by a strange epidemic.

Now, Runar Skoldolfr and Tiberius Grim must lead a small expedition into the haunted vales of the Blood-Rock Peaks to answer the girl's pleas for aid. There, the hunter and the veteran priest of Sigmar will uncover the enigma of a forlorn-looking statue and its curious sway over the town - a place ruled by ancient fear and phobia, zealotry and madness.

Separated and isolated, Runar and Tiberius will learn there are far worse fates than death, for in Calignius friendships turn sour, faith boils into anguish and long-buried nightmares rise up from the shadows. If they are to survive, they will need to find a way to unite against the daemons that divide them.
