Ferrus Manus - The Sapphire King: It was at the precise moment that Ferrus Manus' head was scythed from his shoulders by the Traitor Fulgrim that the Daemonic entity known as the Sapphire King came into being. Spawned from the psychic bow wave of Ferrus Manus' death, this Daemon was forged from the Primarch's frustrated pride, his boiling anger and sorrow, and from his shame. From the moment of its birth, the Sapphire King fed on the repressed emotions of the soul-scarred Iron Hands. It basked in their chained desperation, bound to their fate by the emotions they felt but would not express. The Daemon bedevilled them across the centuries, offering opportunities for damnation disguised as steps away from the weakness they so feared. It nudged the minds of Imperial officials and potential foes, forever seeking to goad the Iron Hands into spending away their humanity like coin. The Chapter bent their every effort to purging the weaknesses of the flesh, never realising that the more they demonised their wants and needs, the greater the hold the spectre of their repressed emotions gained upon them.Following the aftermath of the campaign fought against a massive Ork WAAAGH! dubbed the Weirdwaaagh!, upon the Forge World of Columnus in 249.M41, questions arose in the Iron Council regarding Iron Father Kristos' questionable conduct. In 260.M41, sufficient dissent continued to arise amongst the Iron Fathers in regards to Kristos' behaviour. Only an entire Iron Council could resolve the wider issues raised. Though a fair and logical process, it was not a swift one; the years turned to decades as the Kristosian Conclave ground on over the next couple of centuries.As the Kristosian Conclave reached its zenith in 460.M41, the Sapphire King judged the Iron Hands ripe to fall and set its trap in motion. Each Iron Hand carried within his heart a rancid seed, a bomb of repressed passions that could erupt to destroy him at any moment. The Daemon would simply provide the spark to light the flame and watch the Chapter burn upon a pyre of their own emotions. In that same year, a vast host of Iron Hands descended upon the Gaudinia System. Iron Father Kristos had assumed the mantle of war leader and had assembled more than eight hundred Iron Hands under his control. This was the greatest deployment of the Chapter for centuries, and was accompanied by the majority of the Iron Council. Clan Company Raukaan once again took the lead in a massive planetary assault upon Gaudania Prime and so was at the heart of the abominable trap that was there unleashed.As the Daemonic entity was confronted by the Clan Companies Raukaan and Sorrgol in their entirety on Gaudinia Prime, Iron Father Kristos was corrupted, both body and soul. Everywhere, the adherents of Kristos (known as Kristosians) were overcome by the twisted perfection of strange flesh engines -- the harder they attempted to repress their urges with logic, the faster they succumbed. Howling Daemons of Slaanesh burst forth from tears in reality, and set themselves upon the beleaguered Iron Hands. With them came warriors of the Emperor's Children. Amid the madness, the bejewelled Daemon itself strode forth to confront the Iron Hands.At that moment, Iron Father Kardan Stronos was struck by the revelation that by cutting off their emotions, his Battle-Brothers were only causing themselves to fall to the corrupting influence of Chaos. Their only chance to save themselves was not by cutting themselves off from their emotions, but by embracing them, and shackling them to their iron will. Activating his Vox, Stronos barked commands to the forces around him, ordering them to release their anger, lest their foes destroy them with it. The Battle-Brothers disengaged their inhibitor protocols and loosed furious battle cries. As the emotional floodgates burst open, the Sapphire King shrieked its rage as the repressed energies that had fuelled its spell were vented like steam from a boiler. Freed from the debilitating Warp-craft, the surviving Iron Hands gave vent to their revulsion, blasting the Daemons apart in rains of ectoplasmic filth or tearing them limb from shimmering limb. With a fury they had never before allowed themselves to display, the Iron Hands made short work of their Chaotic foes. The Sapphire King was utterly destroyed and the remaining Emperor's Children were swiftly blasted into bloodied ruin. To ensure the destruction of the surviving machine-spawn, the Iron Hands launched a massive orbital bombardment, ensuring the Daemon Engines' destruction.
