Hector Rex - Siege of Vraks: Lord Rex's most famous action occurred during the climax of the Siege of Vraks in 830.M41, the lamentable Imperial campaign to retake the Imperial Armoury World of Vraks Prime from the heretical Forces of Chaos led by the Apostate Cardinal-Astra Xaphan. It was during the Rebellion on Vraks that Rex uncovered a prophecy via the Emperor's Tarot that the planet could potentially fall and become a Daemon World. To avoid this outcome, Rex lobbied the entire Scarus Conclave to obtain direct control over the war on Vraks and to induct the entire 88th Regiment of the Death Korps of Krieg into his own retinue. Despite objections from the Ordo Hereticus, who claimed that the matter of Vraks fell under their purview and not that of the Ordo Malleus since Xaphan was a former member of the Ecclesiarchy, Lord Rex was elected the Proctor-General of the Conclave of Scarus, becoming the de facto leader of all the Imperial military forces arrayed against the Forces of Chaos in that sector. The battle to save Vraks from daemonic incursion began in earnest, and so Inquisitor Rex and his Grey Knights strike force, under the command of Brother-Captain Arvann Stern, took the fight to the Forces of Chaos. At the height of this conflict, Lord Rex faced the summoned Lord of Bloodthirsters known as An'ggrath the Unbound.The Bloodthirster and the Inquisitor fought, the blessings of the God-Emperor against the insatiable battle lust and hideous strength of the Blood God. Bathed in holy light, Lord Rex fought like a man possessed, until both the Inquisitor Lord and the Greater Daemon were wounded. Lord Rex knew the Bloodthirster's name and hurled it back at the fell creature like a physical blow, for the power of a true name causes a denizen of the Warp to be repelled. As the two foes fought one another, blades leapt to and fro with blinding speed, until Lord Rex was able to focus the power of his mind upon his enemy, stabbing flashes of white lightning into his mighty blade, which impaled the daemon. From the tip of Arias a bolt of power leapt forth, causing the Bloodthirster to stagger, its legs suddenly buckling beneath it. Lord Rex continued to send more bolts of psychic force into the vile daemon, and each bolt's touch clawed its unholy flesh like fire.As the fell creature called forth to its patron Chaos God to lend it strength, Lord Rex plunged the Nemesis Force Sword deep into the beast's chest. A mighty halo of light exploded as Rex unleashed all his power, channelling it along the blade and into the black heart of the daemon. Gathering every last ounce of his power, the Lord Inquisitor willed the creature dead, and thrust his sword again, twisting the blade hard. Though he was sent sprawling to the ground with a bone-crushing blow, Arias was still hilt deep in the daemon's chest, its light burning ever brighter. The foul creature howled its frustration, for it knew that it had been defeated, the life-giving energies of the Warp severed from it, then in a flash of dark energy An'ggrath was cast back screaming into the Warp from whence it came. The daemon-lord was no more.Though Vraks Prime was eventually reclaimed by the Imperium and brought back into the Imperial fold, it was all for naught. For the planet was forever tainted by the foul influences of both Khorne and Nurgle. Lord Rex placed the world under Ordo Malleus quarantine, declaring the planet Perdita, much to the chagrin of the rival Ordo Hereticus. In the years to come, the Ordo Malleus would conduct a long review of what had occurred on Vraks Prime, and it would be Lord Inquisitor Hector Rex's conclusion that the Vraks System should be interdicted. Automated sentry warnings were to be positioned to warn other starships away, and periodically Imperial Navy patrols would sweep through, making sure the system did not become a haven for pirates or aliens, though the planet and its star system would also no longer be of any value to the servants of the Emperor.
