From the mysterious birth of the Emperor's Sons to the fierce battles that broke out when half of the legendary Primarchs rebelled against their father, these peerless warriors and creators of history were among the most glorious champions of humanity. This anthology contains stories of the greatest or darkest deeds of eight of them: from the Angel Sanguinius, who alone bore the burden of his legion's most brutal deeds, and Vulcan, incredibly human by the standards of his brothers, to the surly Perturabo, who combined inventor and architect with bloodthirsty commander, and Horus, who eclipsed his brightest light with the darkness that grew in the depths of his soul.
