The Eisenhorn series is one of Dan Abnett’s most acclaimed works in the Warhammer 40,000 universe. The core trilogy, consisting of Xenos (2001), Malleus (2001), and Hereticus (2002), follows Inquisitor Gregor Eisenhorn of the Ordo Xenos over decades of service to the Imperium. Each novel focuses on a major investigation that tests Eisenhorn’s convictions and forces him closer to the very forces he hunts. The Magos (2018) is a later addition that continues the story.
Xenos introduces Eisenhorn and his warband as they investigate a heretical text and a conspiracy stretching across several worlds. Malleus moves into the politics of the Inquisition itself and introduces daemons. Hereticus brings the trilogy to a climax that fundamentally changes Eisenhorn’s position. The series also includes shorter fiction: Born Unto Us, The Keeler Image, Missing in Action, and Backcloth for a Crown Additional are stories that fill in events between the novels. The Eisenhorn series is widely recommended as an entry point to Warhammer 40,000 fiction for readers unfamiliar with the setting.
