Robbie MacNiven returns to the characters introduced in his short story A Brother’s Confession with the novel Blood of Iax, a Dark Imperium-era Ultramarines story featuring a Primaris-only strike force. Blood brothers Kastor and Polixis – Chaplain and Apothecary respectively – are part of Strike Force Fulminata, and are taking the fight to the invading orks on Ikara IX when the tide turns and Imperial forces hurriedly go on the defensive. The arrival of ork warlord Urgork changes everything, especially as his objectives go beyond simply finding the biggest scrap possible – the canny Urgork has a plan, and it involves Polixis.
