Emperor's Children - Coming of the Emperor: Not long after this great triumph the world's isolation came to an end. From the perpetually twilit sky emerged a flight of Stormbird dropships, heavily armoured and battle-scarred and bearing the Palatine Aquila, the personal badge of the Emperor of Mankind. When he learned of the Aquila, Fulgrim found his memories stirred.Chemos had no real military forces, but the Stormbirds' landing zone had been surrounded by the Caretakers, the planetary police force of the fortress cities. Fulgrim ordered the Caretakers to welcome the strangers and take them to meet with him in Callax.In his private quarters, Fulgrim met with the heavily armoured warriors from the stars, men who represented a true civilisation that possessed all the culture and refinement that Fulgrim longed to return to his homeworld. From amongst the Astartes stepped the shining figure of the Emperor of Mankind, and with one look upon Him, Fulgrim said nothing and simply dropped to his knees before his father and offered his sword in service.Fulgrim swore from that moment forward to serve the Emperor and the needs of the Imperium of Man with all his heart. The Emperor taught His son of Terra and of the Great Crusade He had initiated to reunite all the scattered worlds of Mankind beneath a single rule so that humanity would no longer face possible extinction at the hands of the galaxy's hostile forces. Then it could claim its rightful place as the dominant intelligent species in the Milky Way.Imperial records do not indicate the exact date of the meeting between Fulgrim and the Emperor; all that is known is that Fulgrim's vast flagship, the Pride of the Emperor, was completed by the Mechanicum of Mars 160 standard years before the start of the Horus Heresy in the early 31st Millennium.Fulgrim returned to Terra with the Emperor to meet the IIIrd Legion of Astartes that had been created from his own genome. But Fulgrim learned to his horror that an accident and then the viral blight had destroyed the majority of the gene-seed that had been cultivated from his DNA to implant the Astartes of the IIIrd Legion and that without access to their Primarch's genome, replacing it had proven to be a slow and labourious process.Fulgrim addressed the two hundred transhuman warriors who were then all that the IIIrd Legion could muster. There were so few that each of them bore the banner of a company of the Legion that had either perished, or now numbered only a handful of warriors. They were unbowed and stood with pride, as if in defiance of fate. The Primarch may have seen an echo of the struggle of Chemos in his remaining gene-sons.To them he gave the sacred task of bringing the Emperor's wisdom to all the stars in the sky, "You are the Emperor's chosen, His heralds, His warriors, His children, for this is only the beginning," the Book of Primarchs relates he told them upon their first meeting. On hearing of Fulgrim's words, the Emperor renamed the IIIrd Legion the "Emperor's Children", ratifying a name long known within the Legion since their defence of the Master of Mankind during the Proximan Betrayal early in the Great Crusade but now given the full legal force of Imperial decree.The Officio Militaris' College of Arms recorded the change and marked the IIIrd Legion's panoply as imperial purple with the eagle's talon-spur as their emblem and the unique right to bear the Palatine Aquila as executors of the Imperial will, an honour given only to the Emperor's Children until after the betrayal of the Horus Heresy.Fulgrim was soon consumed by the idea that he and the Emperor's Children needed to live up to the extraordinary honour the Emperor had shown them by becoming shining paragons of the perfection inherent in both the Emperor's person and His vision for Imperial culture and civilisation. The drive for perfection soon consumed the Primarch and his Legion, from the military tactics they employed to the embrace of an unusually artistic Legion culture and a concern for aesthetics and their personal appearances that was unsurpassed by any of the other Astartes.Fulgrim embodied this pursuit of physical beauty and perfection, for long silver hair flowed down his back, his wide eyes and melodic voice welcomed all who sought his counsel and his full lips often quirked into a wry smile. Fulgrim made sure that his Power Armour was of the finest quality that could be fabricated by Imperial technology and was intricately decorated in the purple and golden colours he had chosen for his Legion. Over it he usually wore a wide variety of intricately embroidered and high-collared cloaks.
