Luther - Dark Angels: Shortly after the success of the campaign, the Emperor of Mankind and his Astartes scouts arrived on Caliban in 846.M30 after they detected the psychic emanations of one of the primarchs. From the moment the Emperor landed, Lion El'Jonson felt the deep connection between himself and the Master of Mankind, and swore his fealty. In return, the Emperor made the Lion the commander of the Ist Legion of Space Marines that had been created from his genome.The Emperor launched His Great Crusade after the end of Old Night to reunite all the lost colonies of Humanity and restore Mankind's birthright as the rulers of the galaxy. The Emperor's Space Marine Legions purged entire star systems of Humanity's xenos oppressors. As the Imperium's wave of conquest advanced across the galaxy, Imperial scouts brought word that they had rediscovered the isolated world of Caliban in the Segmentum Obscurus and that it was home to a man who was likely one of the missing primarchs.The Emperor had first sent emissaries from the Ist Legion to serve as His advance force on Caliban, Astartes who had been created from the genome of their lost primarch Lion El'Jonson. The Imperials brought with them all of the advanced technology that was hailed by the people of Caliban as miraculous. Soon, the Astartes of the Ist Legion were putting potential Astartes aspirants from The Order and the other knightly organisations through myriad martial trials and competitions to gauge their level of martial prowess and character.Only the strongest and most dedicated were allowed to pass to the next stage. Many within The Order whispered that they were competing for a place within the ranks of the Astartes. But these trials also served the secondary purpose of determining if the Human strain on Caliban was genetically pure enough to warrant its status as a world that the Ist Legion could recruit from in the coming years.While the Calibanite knightly orders revelled in their differences and often resorted to combat to settle their feuds, the Astartes Legions were united in purpose and will. Such division could not be tolerated, and at the behest of the Lion and the Astartes, the individual knightly orders were disbanded and brought under the control of the Ist Legion.Such a drastic move did not happen overnight, and could not pass without dissenting voices, but when the Lion spoke in favour of the union of the knights and the glory that would be theirs for the taking in the service of the Emperor, most such voices were stilled, most, but not all.The Emperor Himself finally came to Caliban on a day that would live on for centuries in Calibanite legend. His great vessel descended from the heavens and He welcomed his lost son back into the fold. The event was slightly marred by an attempt against the Emperor's life made by certain conservative knights of The Order who feared the changes that would be wrought to their world by the Imperium and its advanced science and culture, but these malcontents were swiftly and mercilessly executed as traitors by the Astartes.More objections were raised when the soldiers of the Imperial Army descended to the surface of Caliban. The Ist Legion's aspirant trials had already identified the likely candidates for recruitment into that august body, but the vast majority of the planet's population would still be able to serve the Emperor as troops of the Imperial Army.Within an unimaginably short period of time, the surface of Caliban was transformed from a world of sprawling wilderness and pre-industrial castles to one of martial industry that rang to the beat of factory hammers and the tramp of booted feet as its populace girded itself for interstellar war.The Emperor's servants descended to Caliban with enormous earthmoving machines that cleared dozens of kilometres of forest a day and left flat, lifeless soil in their wake, ready to be planted or built upon. Mines, refineries and manufactoria followed, ready to transform the planet's abundant resources into vital war materiel for the Emperor's Great Crusade.Cities were built to supply the sprawling industrial sites, growing upwards and outwards with each passing year as the traditional villages and towns surrounding the fortress-monasteries were emptied and their citizens relocated to better serve the Imperium.Finally, the day arrived when those individuals whose courage had been proven beyond doubt, whose stamina, endurance and strength had seen them through the Astartes trials were ready to be added to the ranks of the Ist Legion. Word had come from Luther that the Astartes had made their final selection for advanced training and the genhancement required to join their ranks.Through the application of Imperial science and the marvels of the gene-seed, these aspirants were transformed over the next several years into battle-brothers of the Ist Legion, newly renamed the "Dark Angels" by the Lion after an ancient Calibanite fable.Luther had been chosen to join the Ist Legion by the Astartes, but in common with a large proportion of that initial intake from The Order and the other Calibanite knightly orders, he had been too old to benefit from the implantation of gene-seed. In its place, Luther, and others like him, had undergone an extensive series of genetic, surgical and biochemical enhancement procedures designed to increase their strength, stamina and reflexes to superhuman levels.They were taller, stronger and quicker than mortal men, but for all that they were still not true Astartes. It was difficult for Luther and the others to come to terms with that fact, knowing that they were surrounded by those who had once served under them as squires and junior knights, but were now far more powerful than they could ever hope to become.Luther still served as the Lion's second within the Legion, earning his position based on merit and fuelled with a desire to prove himself by his devotion to the Imperial ideal. But despite his successes, he could not escape his own inner conviction that he was somehow being looked down upon because he was not a full Astartes.
