The Macharian Crusade — William King

In the last years of the Crusade, Macharius comes to Loki. This heavily industrialized world is the bastion of Lord Solar's arch-nemesis, the traitor Richter. Formerly one of Macharius's trusted advisors, Richter's betrayal is indicative of the low morale and dissent amongst the Imperial forces. Brought to the edge of the known galaxy, thrust into a plague-ridden hell of trench warfare, Macharius faces his sternest test. As the end of the Crusade dawns, this could be the end to the Imperium's war and the final fall of Macharius.
