Changes

Following Tallarn, the Iron Warriors were ordered by Horus to man a defensive line of worlds in order to hold off the [[Ultramarines]], which with the death of the [[Ruinstorm]] were advancing towards the traitors rear. Perturabo dutifully oversaw these vicious, bitter sieges. Overstretched and under-equipped, the Iron Warriors once again bled for worlds far from the center of the war without thanks. Perturabo by this point had grown weary and darker, both from the effects of Fulgrim's treachery and the corrupting effects of the Black Oculus. Perturabo's war on [[Krade]] was interrupted by [[Argonis]], who brought orders from Horus to find [[Angron]] and bring both of their Legions for the muster at [[Ullanor]] in preparation for the drive on Terra. Despite having to abandon much of his forces as well as worlds he had fought so bitterly for, Perturabo obeyed the Warmaster and journeyed to [[Sarum]] with a small fleet in search of information of Angron's whereabouts. On Sarum, the [[Daemon]] [[Sa'ra'am]] revealed that Angron was on [[Deluge]] before possessing the body of [[Volk]], creating the first [[Obliterator]]. Perturabo then traveled to Deluge, where he confronted the vicious and corrupted [[Daemon Primarch]] Angron. Perturabo and Angron engaged in a brutal battle, with the Daemon having the clear edge in power and speed. However despite taking many wounds Perturabo endured and goaded Angron, declaring that he was born a slave and now was a slave to Darkness for all eternity. By using the Iron Warriors, [[Iron Circle]], and Volk to out-maneuver and bombard the World Eaters, Angron was bested as an Ultramarines fleet appeared in orbit over Deluge. Angron laughed and declared that they were all now going to die, but Perturabo reminded the Daemon Primarch that he had [[Nuceria|seen his warriors butchered while he had done nothing]] once before. This moved Angron enough to act, and after creating a [[Warp Storm]] the Iron Warriors and World Eaters fleets were able to escape the Ultramarines and move to [[Ullanor]], where they accompanied Horus for the muster.{{Fn|13}}
