Tarkus - First Aurelian Crusade: Surviving the Dark Crusade, the Blood Ravens were led to ultimate victory by Captain Thule in their campaign on Kronus. Tarkus next served with Aramus, the Force Commander of the Blood Ravens operations in Sub-sector Aurelia, the Chapter's primary source of new recruits. He was charged with aiding Aramus in protecting the Blood Ravens recruiting worlds of Calderis, Typhon Primaris, and Meridian.Upon the arid wastes of Calderis, Tarkus fought against Ork invaders, most notably destroying the main entrance to the Fellhammer Mine in order to block access to the Greenskins. Soon after, Tarkus was deployed to find and rescue Sergeant Avitus, who had been incapacitated after fighting against the Orks in a key village.With help from Scout Sergeant Cyrus, Tarkus and the Force Commander managed to eliminate the Orks, revived Avitus and recaptured the village from the Orks before being extracted. Later during the campaign, the Force Commander led the Blood Ravens strike team against two Ork leaders -- a Stormboy Nob named Skykilla and an Ork Warboss called Gutrencha, defeating them both. As the battle wore on, Tarkus, Avitus and the Force Commander redeployed to Fellhammer Mine in order to re-capture it from the Orks.When the strike force of Astartes entered the mine they discovered an Aeldari Warp Spider Exarch and his retinue were already there but the xenos vanished before they could be engaged just as the Orks attacked. Only the timely intervention of Sergeant Thaddeus allowed the strike team to advance again.After capturing a vital communications array, the strike team discovered that an Aeldari force was behind them, stirring up the Orks. The Blood Ravens found the Ork Mekboy Badzappa and his mob under attack by an Aeldari Warlock and a company of Guardians. Although the Astartes slew the Warlock, the wily Ork Mek escaped once again.As the Warlock died, he spoke of the existence of a greater foe that threatened all of the Sub-sector, but the Blood Ravens remained unconcerned by what they took to be the random babbling of the member of a xenos race known for their duplicity.The Blood Ravens next travelled to the jungled Feral World of Typhon Primaris to eliminate the Aeldari activity that had been detected on that world. A Warp Spider Exarch was stirring up the Feral Orks of the Evil Sunz klan located in Typhon's jungles into revolt and he and his force had to be put down. This Exarch mentioned nothing of the so-called "greater foe" once confronted by the Blood Ravens, but Thule asked the Aeldari to return to Calderis as Mek Badzappa was launching an attack against the capital of the desert planet, and its citizens were reporting plants mutating and the appearance of small purple creatures that were killing the local nomads' livestock.The Space Marines returned to Calderis and finally killed the Ork Mek, but they were soon attacked by Tyranids drawn from a probable splinter fleet of Hive Fleet Leviathan who had entered the Sub-sector Aurelia intent on devouring all of its worlds.Once the Blood Ravens successfully destroyed this new threat, they returned to Typhon Primaris. During their time there, Tarkus was convinced by an Aeldari Ranger, named Nemerian, under the guise of a truce, to set aside their prejudice and work together in common cause against their mutual enemy, the Orks. The wily Ranger led Tarkus and his squad in a devastating Ork ambush, which saw the death of the sergeant's entire squad, leaving himself as the sole survivor.Tarkus never forgave himself for the death of his brothers. To add to his ire, the Aeldari Ranger managed to effect his escape during the fight. Weighing heavily upon him, Tarkus' guilt kindled a deep hatred of the Aeldari, which has not lessened over time.The Blood Ravens eventually killed Nemerian, who had been the one stirring up trouble for the Imperium amongst the Feral Orks. After this grim victory, the Blood Ravens returned to Calderis to kill the Tyranid Warrior who had mortally wounded their commander, Captain Davian Thule.Tarkus eventually left the command of the Blood Ravens' Force Commander in the Aurelia Sub-sector and went to the Hive World of Meridian in order to investigate the reason behind the recent Ork appearances at the hive city of Angel Gate. He rejoined the Force Commander's troops whilst they were planetside, searching for the force of Aeldari that attacked the vulnerable Angel Gate.The Astartes discovered that the Aeldari planned to overload the forge's reactor to devastate Meridian and stall the splinter Tyranid Hive Fleet from reaching their own Craftworld of Ulthwé. Tarkus also discovered that the Meridian nobles of House Vandis had warehouses full of stolen Blood Ravens relics. With help from the Force Commander and his strike team, Tarkus captured and defended the warehouse, and later uses a salvaged set of Terminator Armour to assist the Force Commander in defeating the Aeldari Farseer Idranel.Tarkus' last deployment was to the Typhon Graveyard, as part of the Strike Team that was to use biotoxin weapons to damage the Hive Ships feeding on Typhon. After injecting two samples of the biotoxin, the Strike Team made its way to a teleport relay which allowed the Blood Ravens' 3rd Company to deploy to the Strike Team's aid. With help from Captain Gabriel Angelos, the Strike Team eliminated the main Tyranid Hive Tyrant, and defeated the main Tyranid force in the sub-sector.
