None fight with more grim determination than the battle-brothers of the Dark Angels, and their renowned specialised companies – the Deathwing and the Ravenwing – are held in awe by their allies and enemies alike. Working in concert, the formations of the Dark Angels are devastating in battle. Yet behind their devotion to the Imperium lies a shadowy obsession. Haunted by their past, the Dark Angels and their successors – known collectively as the Unforgiven – wage a secret war for redemption, a millennia-long crusade of vengeance that will either lead to their final atonement… or eternal damnation.
