Warhammer 40K lore, Space Marines [2]
In the fading light of the 31st millennium, the furious blaze of the Great Crusade simmered down to mere embers. In this tale, we delve into the abyss that lay hidden in the hearts of the Astartes/Space Marine Legions, an insidious vulnerability that would serve as a gateway for the corrupting tendrils of Chaos, luring half their brethren into damnation. It is a tale of secret societies, the inscrutable Lodges formed in the silent, shadowy recesses of Astartes brotherhood, a cancer that went unnoticed until it was too late. Ultimately, it led to the spawning of the most catastrophic event in the annals of the Imperium: The Horus Heresy.
