The Space Marine Legions of the 31st Millenium field a diverse and formidable range of genetically-enhanced warriors and advanced war machines, superior to any other military force in the galaxy. As an Age of Darkness falls across the stars and the fires of rebellion rage out of control, the armies that were used to forge the Imperium turn upon each other in an apocalyptic civil war – the Horus Heresy. Of the eighteen Space Marine Legions, fully half have betrayed their oaths. Defiant servants of the Warmaster, these Space Marines gather strength to overthrow the Emperor and claim the Throneworld of Terra. In the turmoil of the Horus Heresy, the Traitor armies unleash powers and ambitions beyond mortal reckoning, waging bitter war against their former brothers – those that still cling to their oaths and stand by the Emperor. By the determination and fury of these rebellious warriors will the fate of the Imperium, and that of humanity itself, be decided.
