Aurelian Crusades - Second Aurelian Crusade: Just when all seemed to be returning to normal in the Sub-sector Aurelia, the Warp opened up and spat out the former capital world of the sub-sector and ancient homeworld of the Blood Ravens Chapter, the Ice World of Aurelia.Home to the Blood Ravens' ancient fortress-monastery of Selenon and many loyal citizens of the Imperium, the planet was corrupted by a Greater Daemon of Nurgle known as Ulkair. The Blood Ravens' Chapter Master Moriah had attempted to destroy the daemon but failed, and the weakened daemon was imprisoned in the depths of Keep Selenon by Azariah Kyras, then a Librarian of the Blood Ravens.Yet the daemon's influence proved too strong and eventually the shaken Kyras fell to the taint of Chaos. Aurelia itself was swallowed by the Warp and its existence in the sub-sector that had been named after it was all but forgotten.The ice-encased world returned to realspace in the late 41st Millennium bearing the foul hordes of Chaos, a warband of Chaos Space Marines from the Black Legion led by the Chaos Lord Araghast the Pillager and the former Word Bearers Dark Apostle Eliphas the Inheritor, who had been resurrected by the will of the Dark Gods so that he might seek the destruction of the Blood Ravens, now as a member of the Black Legion.Captain Gabriel Angelos and Force Commander Aramus rallied the Blood Ravens Astartes of the 3rd and 5th Company to face this threat, but no sooner did they join combat then the Aeldari and the ever present Orks rose up to cause trouble along with the heretical soldiery of the Hive World of Meridian's noble House Vandis.Before long the entire sub-sector was embroiled in fresh combat against multiple foes with the forces of Chaos causing havoc at will.As the Blood Ravens scrambled to respond to these threats even more dire circumstances came to light as the space hulk Judgement of Carrion returned to the sub-sector. Determined to recover valuable intelligence and ancient advanced technology from the space hulk to aid them against the foul servants of Chaos, the Blood Ravens under the command of the local Force Commander, Sergeant Aramus, assaulted the Judgement of Carrion only to discover the bodies of fallen Blood Ravens from the 5th Company, formerly members of an expedition led aboard the Space Hulk by Apothecary Galan.As the forces of Aramus investigated the hulk they were shocked to find evidence of Galan's corruption by the powers of Chaos, but the truth of the matter was far more insidious.As Aramus and Captain Angelos desperately fought to keep control of the sub-sector and unlock the secrets of both the Judgement of Carrion and the lost planet Aurelia, they were interrupted by the arrival of Apollo Diomedes, the Captain of the Blood Ravens Honour Guard and the right hand of the Blood Ravens' Chapter Master and Chief Librarian Azariah Kyras. Diomedes ordered all Blood Ravens forces to stand down, an order both Angelos and Aramus promptly ignored.As Diomedes got increasingly sterner in his orders, Aramus and Angelos continued to resist the forces of the Black Legion, with whom the Chapter had recently avoided open conflict for an unknown reason.As his investigations continued, Aramus discovered to his horror that the source of corruption was none other than Chapter Master Kyras himself, who had fallen under the sway of the Greater Daemon Ulkair during his earlier campaign on Aurelia centuries before and spread his taint to Galan aboard the Judgement of Carrion.Kyras escaped the doomed world of Aurelia aboard the Space Hulk and had returned to the Chapter with his dark seed of corruption when he met with Galan's expedition.Daring open conflict with Captain Diomedes' forces in their base-camp on Calderis, Aramus attacked Galan, slaying the Traitor and his tainted bodyguard of Terminators, a battle which ended in a confrontation with Captain Diomedes himself.Reluctant to accept the corruption of his political patron within the Chapter, Diomedes found himself torn but let Aramus and his comrades leave Calderis and continue their operations against the Black Legion warband of Araghast the Pillager. The Battle of Aurelia culminated in the death of Eliphas the Inheritor, who seized control of the Black Legion warband by betraying Araghast and leaving him to the mercies of the Blood Ravens earlier in the fighting.Despite Eliphas' machinations, Aramus was able to re-seal the Daemon Ulkair in its icy tomb within Keep Selenon on Aurelia. Even with this victory, Chapter Master Kyras declared Captain Gabriel Angelos a Renegade and Traitor to the Chapter and Sergeant Aramus found himself faced with the knowledge that the Chapter Master was a corrupt agent of the Chaos Gods.Diomedes and Aramus returned to the Chapter to bide their time, while Angelos fled Kyras' wrath. When the time was right the 3rd Company was determined to return and join with Force Commander Aramus and Captain Diomedes to cleanse the Chapter of the insidious taint that lay like a malignant cancer at its core.
