There are also several short stories available, two of which can be found in the doorstopping omnibus edition. Unlike the previous 3 books, it isn't a first person narrative and predominately focuses on the character of Magos Drusher, a bystander dragged into a case by Eisenhorn himself. The fourth book, The Magos, is set between the Ravenor and Pariah Trilogies, and serves to bridge Eisenhorn's role between the two. The third book, Hereticus, sees Eisenhorn pursued by allies of Glaw and his attempt to stop Glaw from acquiring a world-ending power.

The pursuit of these enemies leads to Eisenhorn uncovering and defeating a much-revered Inquisitor gone to Chaos. The second book, Malleus, begins with a major celebratory parade ruined by Chaos-linked renegades. In the subsequent investigation, Eisenhorn and crew find themselves embroiled in a heretic group's plan to contact aliens for a daemonic text. The first book, Xenos, starts with Gregor Eisenhorn and his crew pursuing a heretic in a seemingly routine task when they uncover a mysterious artifact bearing the preserved mind of the heretic Pontius Glaw. Throughout the books, Eisenhorn finds himself having to use increasingly desperate and dangerous means against his foes. Eisenhorn is a trilogy of novels by Dan Abnett set in the Warhammer 40,000 universe, following the adventures of Inquisitor Eisenhorn and his retinue as they combat the enemies of the Imperium of Man.
