Book three in Black Library's iconic Ultramarines series returns The Ultramarines are the epitome of a Space Marine Chapter. Warriors without peer, their name is a byword for discipline and honour, and their heroic deeds are legendary. Exiled from the Ultramarines Chapter, former captain Uriel Ventris and his battle-brother Pasanius embark upon a deadly quest into the heart of darkness - the daemon world of Medrengard. There, they must destroy a facility creating new warriors for the Traitor Legions - but Warsmith Honsou and his Iron Warriors stand in their way. Can the Ultramarines complete their mission and redeem their honour, or will they join the ranks of the lost and the damned? This edition also includes the prequel short story 'Consequences', in which Uriel and Pasanius face trial for their breaches of the Codex Astartes, with their lives on the line.
