Believing Terra has already fallen to the Warmaster, Primarch Roboute Guilliman founds the Imperium Secundus. The unthinkable has happened - Terra has fallen to the traitor forces of Warmaster Horus Nothing else could explain the sudden disappearance of the Astronomican's guiding light at the heart of the Imperium, or so Roboute Guilliman would believe. Ever the pragmatist, he has drawn all his forces to Ultramar and begun construction of the new empire known as Imperium Secundus. Even with many of his primarch brothers at his side, he still faces war from without and intrigue from within - with the best of intentions, were the full truth to be known it would likely damn them all as traitors for all eternity.

Since the earliest days of the Great Crusade, Sanguinius – angelic primarch of the IXth Legion – was ever among the closest and most loyal of Horus’s brothers. But the Blood Angels have long kept their true nature hidden from the rest of the Imperium, and when the Warmaster hints that the key to their salvation may lie in the ruins of a conquered world, the sons of Sanguinius race to claim it. Now, as the revelation of their betrayal dawns and the traitors’ hand is revealed, the Blood Angels must face all the warp-spawned armies of Chaos, as well their own personal daemons, upon the blasted plains of Signus Prime...

Roboute Guilliman, the Battle King of Macragge, leads his Legion, the mighty Ultramarines, in conquest of the galaxy as part of his father's Great Crusade. Faced with an alien empire, all his dreams of a shining galaxy of peace threaten to fall into ruin... Long before the coming of the Imperium, the realm of Ultramar was ruled by Roboute Guilliman, the last Battle King of Macragge. Even after learning of his true heritage as a primarch son of the Emperor of Mankind, he strove to expand his domain as efficiently and benevolently as possible, with the XIII Legion Ultramarines as his alone to command. Now, facing a rival empire on the ork-held world of Thoas, Guilliman must choose his weapons carefully – otherwise his dream of a brighter future could be lost forever. It's the start of a brand new series of 18 books focusing on the greatest of heroes, the primarchs themselves. This volume kicks it all off with a tale of Roboute Guilliman at the height of his powers, leading his legion into battle at the apex of the Great Crusade.
