Prince Yriel - War Amidst the Stars: For nearly a decade, Yriel led Iyanden's forces against Kallorax's armada. Guided by his own keen instincts and by the divinations of the craftworld's Farseers, Yriel set about isolating and destroying Kallorax's forces. This was not a war of fleets arrayed gloriously for head-on battle, but one of ambush and subterfuge. Yriel began to monitor the spaceways for distress calls, loosing his vessels to the hunt only when an attack was well underway and the pirates distracted with their plunder. The merchant vessels that had acted as unwitting bait seldom survived, but then, such was not Yriel's priority. Better by far that the dull-witted humans could make themselves useful by their deaths than live on to pollute the galaxy with their presence. Even so, a few fortunate vessels did survive, their crews at the fitfully blazing wreckage, wondering at what manner of force had wrought their salvation. Yriel's attacks were not limited to spaceborne engagements; any installation under Kallorax's command was a potential target. Swift-winged Vampire Raiders carried Wraithguard and Wraithblade strike forces against fuelling stations, asteroid bases, monitoring posts and slave yards. They struck without warning and left nothing but ruin in their wake. Little by little, Kallorax's supply chains withered and died.Angered by his losses, but powerless to carry the fight to an enemy whose base of operations was unknown, Kallorax sought ways to "motivate" his minions. Fear galvanised Kallorax's crews where avarice had not, and soon, the Aeldari experienced their first losses. Yet still, Kallorax's anger grew. On the occasions where the pirates actually managed to destroy a more substantial vessel, the losses they suffered in return rendered the success almost meaningless. Yriel's ships were simply too swift and too well led to permit Kallorax anything but the most trivial of victories.Matters finally came to a head at the planet Agrion -- the location of a key orbital shipyard from which the pirates staged their raids. Here, Kallorax finally experienced an Aeldari attack for himself. This was the closest to a conventional naval action the two sides had yet fought, with some four-score Iyanden vessels engaging a pirate fleet nearly twice their number. This was also the closest Kallorax ever came to a victory, for in the throes of battle, his forces managed to destroy or cripple a dozen Aeldari capital ships. Unfortunately, this success cost him half of his own forces. This included the pride of his fleet, the Hades-class Heavy Cruiser Deathless Reaver, whose Warp engines had been breached early in the battle by a pinpoint salvo from Yriel's flagship, Flame of Asuryan.When the pirate vessels at last withdrew in disarray, Yriel ordered his warriors aboard the shipyard. Alas, renegades aboard the shipyard recognised that they had nowhere to run and resolved to make the attackers pay for their temerity in blood. Yriel's forces breached the hangar bays easily enough but, once inside, the Aspect Warrior vanguard were cut apart by a storm of bolter fire. Determined not to fail, the Aeldari pressed on through the storm, but the resistance grew heavier the deeper into the station they fought. The pirates had the flotsam of a hundred battles to press into service, and every access point was defended by barricades and Icarus emplacements. Loathe to lose more lives aboard the shipyard than he had already, Yriel ordered the Aspect Warriors to retreat, and loosed his ghost warriors to the hunt. Guided by the precise commands of Spiritseers, the wraith-constructs advanced through the storm of shells and missiles, weathering blows that would have torn a mortal Aeldari apart. Kallorax's forces fled as Wraithlords tore down the barricades, but there was nowhere to hide from the vengeance of the dead. In a final, terrible battle amongst the coolant ducts of the shipyard's reactor, the ghost warriors scoured the station clean of foes, then used plasma charges to scuttle it.
