Having secured Baal, the Flesh Tearers receive timely reinforcements from the Indomitus Crusade. In that moment of hope, however, they realise they've not heard from their now isolated homeworld of Cretacia in far too long…
Ordered by Gabriel Seth to secure Cretacia, Chaplain Dumah and Apothecary Barachial set course for the Flesh Tearers' homeworld. But when they finally lay eyes on it once more, will they find a garrison standing firm, or a desolate wasteland scoured by their enemies? The Space Marines must walk in the footsteps of their chapter's mythic founder, and along the way they will learn what it means to embrace the Wrath of the Lost – or die trying.
