CONNOR powers

Horus’ armada gathers, and he has defeated all enemies sent against him, even the Emperor’s own executioner. One barrier remains before he can strike for Terra and lay waste to the Emperor’s dream. The Beta-Garmon system occupies the most direct and only viable route to the Solar System and Terra. To break it, Horus assembles a war host of incredible proportions and Titans in untold numbers. To lose here is to lose the war, and Horus has no intention of turning back. But the Imperium understands the importance of Beta-Garmon too.

The Heresy came to Calth without warning. In just a few hours of betrayal and bloodshed, the proud warriors of the XIIIth Legion - Guilliman's own Ultramarines - were laid low by the treachery of their erstwhile brothers of the XVIIth. Now, as the planet is scoured by solar flares from the wounded Veridian star, the survivors must take the fight to the remaining Word Bearers and their foul allies, or face damnation in the gloomy arcology shelters beneath the planet's surface.

The fortress world of Regium has a proud history, For millennia, it has endured when others have fallen to ruin and damnation, standing defiant in defence of the Imperium of Man. But now it is shaken. Parasitic plagues run rampant, and Regium's citizens are haunted by dreams of horrific monsters feasting upon their flesh and marrow. Lieutenant Castamon of the Ultramarines recognises these signs of an impending Tyranid invasion all too well. Rallying his warriors, the battle-hardened veteran launches a strike force to slaughter the xenos in the outer system, before it can reach Regium.
