The True Faith
The True Faith is a horrific amalgamation of mortal Cults, astartes Warbands and daemonic hordes all sworn to the dictates of the True Faith itself, an ideology born of the Word of Lorgar and twisted to serve the purposes of the Daemon-Saint, Azunar and, by extension, the Draziin-Maton, to whom Azunar had pledged eternal servitude. Where once they burned worlds for the Dark Gods, the Ruinous Powers have faded into minor states of reverence, and have been replaced by the worship of the One True God: The Nex- [FRAGMENT MISSING, PLEASE KILL]
During the dark era of the Second Age of Strife, the True Faith had yet to rise. At that time, the Dread Apostle Azunar the Truthbringer was not yet ascended to Daemonhood, and lead the twisted crusades from the front. Not tied down by either Abaddon's Chaos Imperium or Huron's own domain, the Host of the Truthbringer had outposts and launching points throughout both, and ignored the hostilities between the two, instead focusing on their true mission: spreading the taint of the Warp as much as possible.
Even during the time of the Imperium of Man, the followers of Azunar had been obsessed with the Warp, their fanatic dedication to the Dark Gods manifesting as an intense hatred for the veil between worlds. Creating Daemon Worlds was an act of divine justice in their deranged minds, and with the death of the Imperium, they were prepared to march through the galaxy, bringing ruin to all they encountered.
Or at least, that's what would have happened if not for a sudden change in the Apostle's goals. Rather than unleash themselves as a tide of destruction upon the Galaxy, or even aid their legion in the construction of the Chaos Imperium. No, something else was growing. Something of far greater importance.
The Death of the Emperor had awoken….. Something. The Apostle had felt it. Patterns that weren't in the Empyrean before had been forming. Something from the deepest warp was rising and descending, and it's tendrils wriggled their way into the Word Bearer's mind. A daemon of the Deep Warp, disguised as an angel of Ancient Terran faith, guided the Host of the Truthbringer into an alliance with El'Uriaq, promising them an ultimate truth behind the Warp: A truth that would finally grant them the power to defeat the adversaries of Chaos, even the hated Necrons and Tyranids.
Over the course of the Strife, the Host of the Truthbringer gathered Psykers and found ancient Eldar constructs, working alongside El'Uriaq and his cohorts of followers. Until at last, at the dawn of the 46th Millenium, the Host traveled to an isolated Hive World, their Psyker quarry in tow, and undertook a ritual of darkest power. We will detail the nature of this ritual later, but that was the day the Host of the Truthbringer died, and the True Faith was born.
After bringing a portion of the Nex into realspace, and by doing so, erasing an entire Sector from existence, the Host was utterly devoured by the Primal Horror they had summoned. Subsumed and embraced by all that was not, the members of the Host became far more, far less, and far worse than the already insane Astartes they once were. Each and every one of the 1,000 warriors of the Host were possessed by the dreaded Draziin, their bodies turned into roiling, formless Warpflesh contained within their armor, their Dreadnoughts and Helbrutes turned into even more twisted and insane forms. The Sanctified Desolation was renamed the Sanctified Dissolution, after their newfound God. All those Mortals who had found solace in the demented yet welcoming missionaries were turned to writhing spawn, merged with the floor, walls and ceiling of the vast fortress, adding themselves to the twisted, unreal geometries it was now adorned with. The only one spared this fate was Azunar himself, for after the thousands of years of conquest, and the sacrifice of an entire Sector, he became a Daemon Prince of the Deep Warp, a herald of the true End Times. And he would not have had it any other way. He had found God: not the glorious yet limited constructs of mortal urges, but the One True God: True Chaos, beyond all mortal reckoning.
Throughout the Age of Dusk, the True Faith grew, recruiting disparate Warbands and aiding the Daemonmancer El'Uriaq in his work. At that point, Legion of origin mattered not, only allegiance to the faith and the will of the Deep Warp. The original members of the Word Bearer Host became the Exalted, the highest rank of the faith, 1,000 warriors of insane faith and rampant mutation.
At the heart of the Sanctified Dissolution, the Daemon-King Azunar held court with the Draziin-Maton, communing with them over the nature of Chaos and the Deep Warp.
Now, in the 60th Millenium, the Daemon-King prepares for the Last War for creation. The Dissolution must triumph, or all will be lost.
