13th Black Crusade - Xersia: The Imperial campaign against the Dark Eldar, though nothing more than a distraction from the maelstrom of the Despoiler's invasion, soon posted another victory. Another force of Drukhari raiders had been defeated, on this occasion by the Relictors Space Marine Chapter, upon the world of Xersia. The Relictors had not formally acknowledged the command authority of Logan Grimnar's Adeptus Astartes command council, and appeared to have launched this attack upon their own initiative, not as a response to command council directives. It was believed by the Cadian High Command that the Drukhari's raids simply attracted the Chapter's attentions, and the raiders paid for their crimes in blood.Xersia was a well-garrisoned star system, and many of the Imperial forces present there witnessed the Relictors' assault. It was said that the Chapter slaughtered three entire Kabals, purging the system and hunting down every last xenos before slaying them without mercy. The Chapter's officers were said to bear arms of terrifying potency: swords able to spew cleansing flame, and axes that sucked the essence of the Emperor's foes from their bodies, leaving nothing behind but a dried husk. The Chapter marched under arcane banners and icons of tangible power, the followers of their enemies scattering before them. The Relictors delivered the Emperor's wrath wherever they passed. A number of Imperial Guard officers on the ground at Xersia attempted to contact the Relictors' Chapter Master, Commander Artekus Bardane, but the Chapter Master refused to acknowledge their communications.Subsequent to this action, the Relictors appeared in a number of other campaigns before arriving in the Cadia System. The Chapter was known to have participated in an attack against a warband of the Word Bearers Traitor Legion on the world of Subiaco Diablo, during which an Inquisitorial task force disappeared under suspicious circumstances. They were next seen in the Cadian Sector, where they clashed with a Night Lords force at Exeltra Minor, before becoming embroiled in the suppression action against the Drukhari raiders at Xersia. The Chapter next appeared near Cadia itself. Upon their arrival in-system, the Great Wolf Logan Grimnar issued orders that the Chapter should reinforce the Imperial garrisons of Cadia. Commander Bardane refused to acknowledge Grimnar's orders, and his fleet departed the system, headed, by best estimates, for the Agri-world of Fremas. Grimnar was furious that the Relictors had refused to submit to his command. In a fit of rage, Grimnar ordered his most elite Wolf Scouts to track down the Relictors and discover the true nature of their mission.Exactly what occurred at Fremas is a matter of some doubt, but the Pack of Wolf Scouts despatched by Logan Grimnar tracked the Relictors to the remote Diamedes Archive, where the Chapter appeared to have repulsed a Chaos attack before turning upon the Archive's defenders. None of the defenders were reported to have survived the assault, but Grimnar's men recovered partial video-logs that suggest the Relictors' objective was the sealed stasis vault at the heart of the mountain top fastness. The contents of this vault were known to but a handful of Adepts in the Imperium, most of whom resided on Terra. The Relictors' actions would later put them in conflict with both the Inquisition and later, the High Lords of Terra, which put the future of their Chapter in dire jeopardy.
