Editing Negators (section)

===The Battle of Malphas===
The first open act of Heresy committed by Negators forces was far from the Betrayal at Cadia, on a distant world on the outer reaches of Segmentum Obscurus, where Aodhán, along with his brother Sarco Funerus and the lion's share of their Legion strength had been tasked with returning Imperial rule to a cluster of defiant systems. The campaign was thought to be a bloody but mercilessly quick one by initial estimates, the presence of unrecorded psyker cults and allied xenos at work against the Legions only serving to briefly extend the duration of the war. The true purpose of their mission to Malphas, however, was to place the Scions far from the light of Terra, where Aodhán could attempt to either convince his brother to the Warmaster's side or cut him down. The two Primarchs fought amidst the ruins of Malphas' halls of governance, Sarco's Contemptor chassis sustaining heavy damage before their duel was interrupted by the arrival of then-Captain Idrias Stern and Asoborn Levan, a Negators Legionnaire with little taste for betrayal. Though both Idrias and Asoborn sustained such injuries that they were interred in the aftermath of the battle, their intervention allowed the Undying Scions to extract their Primarch, who ordered a fighting retreat off Malphas, intent on making for Terra with all due haste. The Negators would continue to hound them for much of their journey.
