Inquisitor Lord Hieronymo Drake is dead. Much like the sector itself, the Macharian Inquisition is in disarray — but one Inquisitor has risen to the challenge of uniting them in Conclave. Beyond the countless heretics, daemonic influences and foul xenos lurks a threat that, left unchecked, could consume the whole sector. Can the conclave’s Inquisitors and acolytes put their shadow wars aside and work together to purge this threat before it threatens the entire Imperium? The Inquisition Guides bring the Holy Orders of the Emperor’s Inquisition to life at your gaming table. This second half of a thrilling two-book set for Warhammer 40,000 Roleplay: Imperium Maledictum, the Inquisition GM’s Guide gives you all the tools and content you need to craft unforgettable and perilous investigations for your players and their acolytes.
