Editing Onyx the Indestructible (section)

===Youth===

According to the traditions of the [[Stone Men]], Onyx the Indestructible was the last of the [[Primarchs (Hektor Heresy)|Primarchs]] created by the Emperor of Mankind. In this account, the other Primarchs were mere trial runs before the finished product could be assembled, and for this reason the Stone Men and their successors generally hold that the Hektor Heresy was inevitable once Onyx's incubator was stolen away from the Emperor's laboratory beneath the Himalayza Mountains and the Primarchs were deprived of their intended leader.

The Primarchs' loss was Neolithus' gain. A Feral World at the time that Onyx's capsule crashed to its surface, Neolithus was a world of vast, steaming jungles inhabited primarily by a breed of gigantic ant-like cyborgs under the direction of a malevolent supercomputer. We do not know what these creatures called themselves and in Onyx's own account they are referred to simply as "Cybants". Regardless of their identity, the Cybant hive had driven the native humans into savagery and to the brink of extinction, but the coming of Onyx would change all of that. Both the cybants and human hunters nearby saw the descent of the Primarch's capsule and hastened to claim whatever bounty had fallen from the heavens.

Unlike those of his brothers who were welcomed into their worlds by human hands, Onyx fell into the grip of the Cybants. The cybernetic horrors claimed his incubator and carried it away to their lair, where it was investigated by more sophisticated models under the direct control of the central intelligence. After a lengthy investigation, the Cybant hive managed to open the incubator - and infant Onyx, already the height of a human youth, leapt out to smash its sophisticated servitors. The dispatch of warrior models failed to contain the young Primarch and Onyx rampaged through the hive, laying waste to the Cybants until he found the supercomputer itself. The machine tried to bargain with Onyx, but either the infant did not understand or did not care to bargain. With one blow of his mighty fist, the Primarch destroyed a menace that had almost annihilated Neolithus' people.

Destroying the nerve center of the Cybants killed most of the drones. The remainder moved about at random, heedless of any danger until they died. For the humans of Neolithus, it was obvious that a great miracle had delivered them and the wisest among them knew the light in the sky was the cause. Eventually a few bold scouts ventured into the Cybant lair to pick the bones of their nemesis, and there they discovered Onyx supping on Cybant haunch. Incredulous at first, the scouts soon learned that the "boy" was far more than he seemed and hailed him as their saviour. Over the next three years, the Primarch grew to his full stature, mastered the tongue of the natives, was given the name Onyx Lithus - he who banished the night from Lithus - and was recognised as God-King of the Planet. He lived in as much luxury as he desired and directed his adoring subjects to better their condition through many ingenious schemes of his own devising.

This tranquil life was interrupted by the coming of visitors from the stars. A mighty giant in golden armour strode out onto the surface of Neolithus, directing its minions to gather up specimens for his great interstellar zoo. Hybtar the Collector, for the giant was none other than that miserly xenos, was eager to sample the fruits of Neolithus and a creature as singular as Onyx was the most precious of prizes. Although Onyx was too mighty for Hybtar's entourage to subdue, the alien seized the people of Neolithus and threatened to kill them unless Onyx surrendered himself. Above a chorus of weeping, mighty Onyx gave himself up to save his people. From his beloved home, the Primarch was taken to Hybtar's immense space station, there to be exhibited for the amusement of the alien and its guests.

For many days, Onyx raged in his enclosure, trying to smash open an exit even to the killing Void outside. He struggled in vain. For all of the Primarch's might, Hybtar's station was fitted with powerful force fields that secured its enclosures. Only by learning the languages of his fellow captives - the Eldar Princess Yvanna, the sentient crystal Adj'Manax, and the ancient reptilian Bitol q'Thop - through long and patient study could Onyx break free. Bitol q'Thop, nearing death and sensing the character of a true hero in Onyx, gave up the last of its life force to project an illusion through Adj'Manax's crystal structure. This semblance fooled Hybtar's minions into believing that Onyx had escaped and the dupes willingly opened up the Primarch's enclosure to investigate. It was their final act. Onyx quickly freed his companions and then took a moment to honor the long life of Bitol q'Thop before moving on with the next phase of his plan. Princess Yvanna stole away to the station's launch bays, using her people's legendary guile and grace to evade detection. Onyx, with Adj'Manax upon his back, made for the core of the station to seek revenge. While Hybtar's guardians were fierce and heavily armed, but against the Primarch's might they stood little chance. The alien itself was another matter. Adj'Manax had slowly reshaped itself into an armoured carapace around Onyx's vitals and it was this precaution that saved the Primarch's young life when Hybtar greeted its former captives with a blast from an advanced energy weapon. Shocked by Onyx's survival, Hybtar had no time for a second shot before the battle became a hand-to-hand struggle for survival. Hybtar and Onyx fought throughout the station, throwing one another through walls and bulkheads alike until the vast structure's integrity began to fail. Even with the station collapsing around them, the two collusi continued to brawl, until finally Onyx drove them out into the Void. There, the Primarch seized his foe and smote him with a tremendous blow, sending Hybtar hurtling towards the nearest star and annihilation. For minutes Onyx and Adj'Manax tumbled through the Void, slowly growing more distant from the ruins of Hybtar's station. Both were resilient to the rigors of hard vacuum, but it is no exaggeration to say that their lives were saved by the arrival of their comrade Princess Yvanna in a hijacked shuttle.

Adj'Manax's homeworld was long gone, and Onyx had little knowledge of stellar navigation at this point. Only Princess Yvanna knew her way home, and on the long voyage to [[Craftworld_Eldar_(Hektor_Heresy)#Craftworld_Sgathan-Ra|Sgathan-Ra]] the three had many adventures, sealing their friendship and discovering strange technologies such as Onyx's Igneous Cannon. Yet their journey did not end at the home of Princess Yvanna. Her father, King Ku'Kyullain the Dark was grateful enough to Adj'Manax and Onyx, but he could not permit the two to stay on Sgathan-Ra. As a token of his thanks, the Eldar King summoned Harlequins to guide his daughter's companions to their rightful home. Before their parting, Princess Yvanna pressed her elegant hands against Onyx's and pledged that they would meet again one day - a scandolous gesture only barely tolerated in the ranks of the Eldar. Onyx's journey through the Webway was bizarre, though the Harlequins' knowledge of the secret ways kept danger at arm's length. In a matter of days, the Primarch had traversed vast reaches of space and arrived at Ancient Terra, the homeworld of his mighty father and the Imperium of Mankind.
