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.

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.
