'In the fighting pits of the Conqueror, Khârn and his fellow World Eaters compete in ever-bloodier contests of carnage and mayhem. As the Butcher’s Nails dig ever deeper into their brains, the Legion have forsaken the Crimson Path. Now they walk a darker, more dangerous road: the Eightfold Path.'

'Darnath Lysander is a man tortured by his past, a past in which the Iron Warriors play a prominent, and unpleasant, role. As the First Captain of the Imperial Fists must choose between the lives of innocents and the death of one of Perturabo’s sons, he recalls a similar incident that haunts him still, and must decide what mistakes are worth repeating.'
