Roboute Guilliman - Ultramar: Around the time that the young Roboute Guilliman waged war in Illyria, the Emperor's Principia Imperialis fleet of the Great Crusade had reached the planet of Espandor in ca. 832.M30 at the outer edge of the network of worlds with which Macragge had maintained tenebrous contact. From the Espandorians the Emperor learned of the existence of Macragge and the extraordinary son of Consul Konor Guilliman, and from what He learned He knew that this child could be none other than a missing primarch.There have been some who have suggested that the Emperor's arrival at Espandor and the isolated region so far from the frontline of the Great Crusade's main spur of progress was no accident, and that by some arts He had perceived or had foreknowledge of what He would find. Regardless, what followed was certainly not foreseen.As the Emperor's fleet quickly moved on to Macragge, it was almost immediately deflected by violent Warp squalls which had risen up to separate Macragge and a handful of nearby systems from approach. Thwarted by a power even the Emperor could not readily ignore, it would be something in the region of five standard years before contact could be successfully attempted.In the years that intervened, Macragge had undergone a striking transformation. It was now a world of uniformity and order, prosperous and productive. Its cities had been rebuilt in glittering marble and shining steel, and the serried ranks of its armies were well-armed and well-equipped, and outfitting themselves now for operations beyond their own world.For even before the Emperor's arrival, Roboute Guilliman, it is said, had dwelt much on the ancient histories contained from his world's deposed aristocracy, and the fragments he found there telling of the ancient interstellar domains of Mankind, and he had begun to dream of new horizons and new worlds to conquer, of a domain "beyond the seas of night" or to use the ancient scholarly form found in the text -- "Ultramar."By his will, he made it so and within their Warp-sealed enclave, vessels from Macragge now plied regular and well-patrolled trade routes with local star systems, bringing raw materials and people to the flourishing world, while against some of its neighbours, short, victorious conflicts had already been waged to pacify the strife they had found there.It is said that when the Emperor finally saw what His lost gene-son had wrought in 837.M30, He was indeed pleased, and that He met Roboute Guilliman without the dissembling that had been needed with those primarchs He had found of more savage timbre, such as Leman Russ, Ferrus Manus, Mortarion and Vulkan. It is further recorded that once Guilliman learned the truth of his origins, he immediately swore his fealty to the Emperor, who he knew was his true father, for he had already theorised correctly the purpose for which he had not been born so much as deliberately created.It was immediately apparent to Imperial observers that Roboute Guilliman possessed a powerful analytical intelligence, even when compared to the transhuman cognitive abilities of his peers, as well as a talent for statecraft and macro-organisation of staggering potential. Yet few could then guess what such talents harnessed to the Great Crusade would go on to achieve.
