Iron Hands - Coming of the Emperor: When the sky was split for a second time in the history of Medusa, the clans were confused, unsure of what this sign might represent. Without a word, Ferrus Manus left the clans immediately and travelled to the landing site of the phenomenon. Weeks passed with no news of Ferrus, but before the clans decided what they should do in regard to discovering the fate of their saviour, the sky erupted with titanic electrical storms and the ground shook to savage earthquakes, terrifying everyone. These events lasted for eight days, after which the entire world was said to have fallen unnaturally silent. A single day later, Ferrus returned to the site of the clans' great meeting, escorting an awe-inspiring figure. Stories concerning what acts the two great men performed vary, but most revolve around the common theme of a battle or trial of powers, responsible for the unnatural storms. Whatever had happened up in the mountains, it was clear to everybody present that there was now a close bond of mutual respect between Ferrus and the Emperor, who had arrived in search of His son. Ferrus Manus soon left with the Emperor to visit Terra, the world of his birth, and become acclimated to the customs and technologies of the Imperium of Man. Yet he promised the clans that he would always return to Medusa, the troubled world that would remain his true home.When the primarch of the Xth Legion was discovered, he was among the first of the Emperor's lost sons to be found, and, like Horus Lupercal and Leman Russ before him, had risen to become a warlord in his own right on the world on which he had been cast. So it was that Ferrus Manus' transition from planetary warlord to general of the Great Crusade was a swift one, aided by his evident hunger for the task set before him and the uncompromising intelligence and diligent application to this greater challenge he displayed. In a scant few years, Ferrus Manus was transferred full control of the Xth Legion which he took command of body and soul, renaming it and remaking it in his image. Sweeping away much of what had gone before by way of organisation at a stroke, the Primarch took the Xth Legion apart with the precision and intent with which an artisan might deconstruct a mechanical chronograph, reconfigure its components and re-assemble it in a fashion more to his liking.When Ferrus Manus took charge of his Legion, he, like most of the other primarchs, used his foster-world as the base and principal headquarters of his Legion. In doing this he wedded the two: the Medusan people and the Terran-founded Xth Legion together forcibly, creating something new that shared aspects of both that had gone before and eradicating with bloody-handed ruthlessness anything that would not yield to his will. Where once there had been Chapters as constituent units of the Legion in the Terran style, there would now be Clans, but this was not a mere symbolic union, and Terran Space Marines were ordered to displace the existing Clans' rulership both temporal and spiritual in the only way that the Medusans knew; by brute force. So the Iron Hands became the new Medusans; the Astartes walking among them as demi-gods, and the people of the nomad clans under their thrall fighting and dying not simply just to survive any more, but ultimately for their children to prove worthy to join the Iron Hands Legion's ranks.The installation of the Iron Hands on Medusa and the establishment of Imperial Compliance over the world did little to alleviate hardship, halt conflict or undo the barbaric superstitions of the natives. Ferrus Manus saw to that, for the trials and hardships of life on Medusa would winnow the weak from the strong and see that only the physically fittest, most warlike and psychologically "suitable" recruits would join the ranks of his Legion. To counteract the potential flaw of Medusa's small population base, Ferrus Manus saw to it that on suitably recalcitrant Human worlds his Iron Hands conquered by force, he exacted a tithe in perpetuity of strong male youths, taking them in early adolescence and selected at his behest by mendicant priests of the Mechanicum as tribute to Medusa: there to live, struggle, fight and survive if they were strong enough, as fresh blood for its clans. Should they prove worthy, they would become Aspirants for his Legion upon attaining their majority. So it was the bloody inheritance and bleak creed of Medusa was spread to successive generations of the Iron Hands, forging the Xth Legion into a weapon of unparalleled ruthlessness.
