A Company of Blood Ravens Space Marines, led by Force Commander Aramus, are sent to quell a rebel uprising led by House Vandis. Only when they are thrust into battle do they realise their true
foe is much more dangerous, and the rebellion is merely a front for a Chaos warhost. The Blood Ravens hunt the Black Legion and their followers throughout the system, but as the strain of
frontline warfare takes its toll, the Blood Ravens must draw on their reserves of faith in the Emperor to resist the lure of Chaos.
