Supreme Grand Master Azrael summons Lazarus and his Fifth Company to honour an old debt on the Knight world of Reis – a planet upon which the warp has set its hungry gaze.

In the darkness beyond the galaxy, there are monsters. Some swim closer to the light, drawn by the beacon that is the Astronomican, while others stalk the Void, predators in the dark. The Carcharodons have hunted for millennia, but now they are drawn into a new blackness...the Dark City of the drukhari itself. Commorragh. For a thousand years, Chaplain Tangata Manu has searched for a relic lost under his watch: an ancient thing, once charged into the keeping of the Forgotten One himself. But at the brink of seeing his hunt fulfilled and the relic returned, it is stolen from under him.

After seven years of bitter war, the end has come at last for the conflict known infamously as the Horus Heresy. Terra now lies within the Warmaster’s sights, the Throneworld and the seat of his father’s rule.

But the way to the Throne will be hard as the primarch Rogal Dorn, the Praetorian and protector of Terra, marshals the defences.
