In the far future of the 31st Millennium, a War Without End is being fought among the stars; the Horus Heresy. The Empire of Man, once united in the Great Crusade to unite the disparate worlds of humankind, stands divided, mired in the most destructive and bloody civil war imaginable.
Horus, favoured son of the Emperor and greatest of the Primarchs; the genetically-forged demi-gods and leaders of his legions of super-human Astartes, leads a full half of his brothers in rebellion against those still loyal to his erstwhile master.
Corrupted by the malign powers of Chaos; the insidious Lovecraftian influence of entities from beyond this universe; he wages a war for the very soul of mankind. A war that will see horrors unending unleashed should he succeed.
Arrayed against him are those of his brothers still loyal to the Emperors vision, desperately fighting to preserve a golden future that may already be lost.
Amidst this carnage, Astartes warriors and even mundane humans strive to navigate the chaos of this conflict of god-like beings and warfare on an apocalyptic scale.
