On the fringes of the Cicatrix Maledictum, the Black Templars of the Second Dorean Crusade tear through the void to join the crusade fleet on the sands of Tempest - an ancient, storied shrine world. Assailed by the murderous warbands of the Blood God, the crusade has come to burn the planet clean of the Ruinous Powers once and for all.

But when a violent warp storm scatters the fleet, the Dauntless Honour is left battered and alone in the void. Besieged by doubt, Castellan Emeric and his brothers must cling to their faith and carve a way to Tempest. For it is there that their battles will truly begin, and the cost of victory may be more than even they are prepared to pay.
