United States? claimed Horus. We are however the devices of his will definitely to obtain prestige of the galaxy before his climbing. When the fights more than, we will definitely be discarded, for we are flawed manufacturings, made from the huge womb of uncreated night. Also before our births, the Emperor cast us apart when he may have conserved us. You bear in mind the problem of Chemos, the marsh it was when you was up to its exploded hinterlands? The pain you experienced there, the discomfort most of us sustained in the worlds where we expanded to participant? All of that might have been stopped. He can have quit all of it, nonetheless he cared so little for us that he just relent. I saw it happen, my brother, I saw it all.

My brother, hear me. Warriors of the XVII th Legion, hear me. This violence is against the code of the Legiones Astartes and against the will of our father, the Emperor. In the name of the Five Hundred Worlds of Ultramar, I implore you to cease fire and stand down. Open communication with me. Let us speak. Let us settle this. This action is an error of the most tragic kind. Cease fire. I, Roboute Guilliman, give you my solemn pledge that we will deal with each other frankly and fairly if these hostilities can be suspended. I urge you to respond."Many human civilians and soldiers suffered terrible radiation burns, which remained with them for the rest of their lives. Although these burns were painful and unsightly, the survivors of the Battle stubbornly refused to have them surgically removed, declaring that the "Mark of Calth" was a badge of honour.

Erebus had managed to complete his blasphemous ritual on Calth's surface, which summoned a Ruinstorm to the galaxy's Eastern Fringe -- a monstrous Warp Storm larger and more destructive than anything space-faring humanity had witnessed since the days of the Age of Strife. It would split the void asunder, dividing the galaxy in two and rendering vast tracts of the Imperium impassable for centuries. On the verdant fields of Komesh the Ultramarines 9 th Chapter died, its half-assembled ranks overrun by a tide of scarlet warriors and armoured vehicles under the command of Foedral Fell. Small islands of cobalt blue shone sporadically across the plains as individual companies and small detachments made brave, but futile stands with whatever weapons and munitions that were at hand. The fighting at Komesh was to be some of the bloodiest of the entire engagement, with upwards of 15,000 Ultramarines slain; the survivors, barely 5,000 strong, would later fight their way free under the command of Tetrarch Tauro Nicodemus in a running battle that would last almost twenty long hours. Further north at the muster camps of Erud, within sight of Numinus City, engines of the Titan Legio Suturvora scattered and blasted elements of the 1 st, 2 nd and 3 rd Chapters of the Ultramarines Legion.There were many portents of the tragedy soon to unfold upon Calth. Given the extraordinary thoroughness with which the XIII th Legion maintained its readiness, it might have been considered tragic, or incompetent, that so few were heeded. The first signs of the Word Bearers betrayal was the minor interruption in Vox traffic around Calth that was attributed to solar distortion -- the void was known to forever creak and whisper around the audible and electromagnetic ranges. Soon there were various reports of a voice chanting over Calthian Vox-links in Calth space. This eerie chanting soon interfered with the main orbital data-feed between the orbital installations and the surface of Calth for several seconds. An hour later, there were two more bursts of such interference, the source of which remained undetermined. Calth Communications Control reported an hour later that there were "a series of malfunction events" and warned that further communication disruptions might be expected during the day until the problem was identified. An hour after that, on the night side of Calth, the first of the bad dreams began. At around Mark -16.44.00, Magos Uhl Kehal Hesst noticed a foreign scrapcode infesting the cogitators controlling Calth's orbital defence network. The source of this scrapcode was a Chaos ritual being conducted in secret at the camp of the Word Bearers' auxiliaries, The Brotherhood of the Knife. [2d]. This ritually-produced scrapcode, known as the Octed, was finally implanted at Mark -7.55.09.
