The Space Marines are humanity’s champions, their loyalty to the Emperor beyond question. When a Chapter falls from grace, the Imperium will stop at nothing to hunt them down and exterminate them. Whilst fleeing the wrath of the Imperial Fists, the disgraced Soul Drinkers Chapter seek refuge in an uncharted region of space in the hope of taking on precious fuel for their battle-barge. Upon making landfall, they are confronted by the stark horror of a world devastated and stripped of all life. Only by finding survivors on another planet in the sector can Sarpedon and his battle-brothers get to the root of this terror. But soon the Soul Drinkers find themselves fighting for their very lives, against a deadly new enemy – the necrons!
