Collection: Horus Heresy

The Horus Heresy is a series of science fantasy novels set in the fictional Warhammer 40,000 setting of tabletop miniatures wargame company Games Workshop. Penned by several authors, the series takes place during the Horus Heresy, a fictional galaxy-spanning civil war occurring in the 31st millenium, 10,000 years before the main setting of Warhammer 40,000. The war is described as a major contributing factor to the game's dystopian environment.
