What if the aftermath of the Great Rift saw yet another fundamental change in the Word Bearers, something even Lorgar couldn’t have foreseen? What if they realized...they were wrong?
As Mortarion witnessed himself firsthand and many amongst the ranks of Chaos are gradually beginning to witness themselves, with the return of Guilliman the Emperor has become active like never before and even manifest to a degree that he has tossed aside Daemon Primarchs like they were mere toys and smoothed the Warp ahead of Guilliman’s fleet to aid his cause in preserving His Imperium.
And recently, the existence of the Anchorite was revealed, a loyal Word Bearer who has accepted the Emperor is a god and has spread His teachings for over 10,000 years after seeing the truth of his deception by Chaos on Calth. Once the Word Bearers learned of his location, they sought to rescue him only to discover he had no desire to go with them and bore witness to the might of the God-Emperor manifesting through him before being forced to flee in failure.
If one Word Bearer could shake off the trappings of Chaos and embrace the Emperor as his one true god again, could not more do so especially after seeing the manifest might thereof for themselves?
I would love to see the revelation of the Anchorite slowly plant a seed of doubt within the Word Bearers and, for the first time in countless millennia, truly begin to question the faith Lorgar poisoned them with.
As they begin to increasingly see for themselves the power of the God-Emperor manifest, I think it wouldn’t be unreasonable for some to come to the conclusion that though the Emperor wasn’t a god at first, He most certainly is now and one evil the Pantheon fears. And moreover, He is the god they should never have stopped worshipping.
Imagine a splinter faction slowly establishing itself in utter secrecy within the Word Bearers in the same way the Lecticio Divinatus slowly grew within the Imperium.
Imagine Word Bearers who would now see Monarchia as a test, and one they failed as well as their Primarch by the God Emperor-not-yet-manifest. They would see Him taking the Golden Throne to truly become the god of Humanity that they always believed Him to be and chastise themselves for losing their faith so easily in the face of adversity.
In time, they would even come to hate Lorgar himself as a weak fool whose fanatical need to worship something saw him easily manipulated into holding his faith cheaply. He didn’t just betray the God Emperor and the Imperium, he damned himself as well as his sons.
No more would his sons be the willing harbringers of his failure, but rather carve a new epic for themselves and take their place as the most fervent servants of the God Emperor as they were always intended to be.
Though the Imperium may never forgive them, they resolve to serve the Emperor as true martyrs and carry His wrath to all of their former brothers and the other deluded worshippers of the Ruinous Powers until the last warp tainted heretic breathes their last.
For the Emperor!
