The Horus Heresy Book Five - Tempest
|Preceded by||Book Four - Conquest|
|Followed by||Book Six - Retribution|
Previously isolated from the brutal devastation of the Horus Heresy as it tore across the Imperium, the Ultramarines were drawn into Mankind’s civil war when betrayal reached Ultramar. The Horus Heresy Book Five - Tempest tells of the Word Bearers’ treacherous attack on the Ultramarines at the mustering world of Calth. This cataclysmic battle engulfed the entire system, pitching not only the Legions against each other, but also the massed ranks of the Imperial Army militia and the towering god-machines of the Legio Titanicus.
