Lorgar - Rebirth: After the razing of Monarchia, the history of the XVII Legion divides. One is the history of the Legion that the Imperium believed existed for solar decades after, the history of a Legion pulling itself from the pit of the past and embracing its true calling, a false history. The second is a shadow history, the true history that hid behind the mask of seeming loyalty. This true history can never be known, and what Imperial scholars do know of it are only distorted glimpses.On the surface, Lorgar's response to the Emperor's censure was to withdraw. For a time his Legion seems to have played little part in the Great Crusade. When they returned to action, it was clear that they were a changed force. Whereas before they lingered after conquests, now they drove forward with relentless momentum. Worlds burned, civilisations were made to kneel, and a trail of swift conquest and Imperial Compliance actions stretched behind them like a bloody cloak. It is said that the Emperor was pleased that His son had understood his error and would, in time, become what he was destined to be. To every other eye, the Word Bearers seemed possessed by a penitent fury and grim resolve to burn the past. All were deceived.That Lorgar was shaken by the shattering of his universe seems likely, but what action did it prompt? At the time some thought that the XVII Legion had withdrawn in shame, and that its return to the Great Crusade was fuelled by a wish to atone. Such a kind reading of events no longer rings true. Instead it seems likely that Lorgar's fall began after Monarchia, that the dark powers of the Warp reached out to him in his moment of doubt and offered him that which the Emperor had denied him: a higher power to believe in.It is not known whom these voices were that counselled him, and the hands that guided him to damnation. Again much remains hidden, but a number of candidates seem likely. Kor Phaeron, Lorgar's surrogate father on Colchis and close advisor, seems a likely source of poison, as does the Legion's First Chaplain Erebus. Both were steeped in the Old Faith of Colchis, a faith that was likely tainted by the four major powers of the Warp long before Lorgar fell from the sky. The word "Pilgrimage" is also one of the few fragments that has emerged as linked with that time, thought its precise significance can now only be guessed at. What cannot now be doubted is that the Word Bearers who re-joined the Great Crusade after the razing of Monarchia no longer served the Emperor.For over four solar decades the XVII Legion wore a false face of loyalty and planted the seeds that would eventually bloom into a galaxy-spanning civil war. The precise nature of their preparations is only open to supposition, but much can be deduced from Lorgar's character and the atrocities that would come later. First, it seems likely that the Word Bearers' renewed energy in the Great Crusade was a cover for its rapid growth in size, as well as the seeding of its new corrupting creed and belief in Chaos onto new worlds.It must also have been during this time that the XVII Legion was cleansed of dissent. The last of the old Iconoclasts and Imperial Heralds, the few Terran-born Astartes still among the Legion, and those who would not embrace the new faith must have been put quietly to the sword. The corruption of much of the apparatus of the Imperium also must have occurred in this time. So it was that when Horus finally fell to the temptations of the Ruinous Powers, Lorgar had already long prepared the ground for the civil war that was to come.
