Across the war-torn systems surrounding the Cadian Gate, Traitor Legions, renegade warbands, and daemonic forces carve their own paths of destruction. As these factions clash with the scattered remnants of the Imperium, a far more calculated threat begins to take shape. On the grim world of Medrengard, stronghold of the Iron Warriors, a far-reaching plan of conquest is set into motion.
