Following the atrocities Horus committed in the Isstvan system, war broke out across the galaxy. Learn more about these early battles.

The early battles of the Horus Heresy ranged from planet-wide devastation to smaller, but still bitter, battles. See what big plans were made, and some of the unintended consequences – such as Lord-Captain Morrachi of the Blood Angels and the 78th Expeditionary Fleet remaining ignorant of the civil war until it concluded.
See what each Legion was up to following the breaking of the Ruinstorm, and learn more about the Knights Errant, Shattered Legions, and the so-called Blackshields. This lore was originally published in The Horus Heresy Book Six: Retribution, released in 2016.
Grab a MKII Tactical Squad and get ready to re-fight these early battles. Then, join us next week when we take a look at the Conquest of the Coronid Deeps.
