Battle of Biel-Tan - A World-Ship Fractured: The most integral part of any Asuryani craftworld is its Infinity Circuit -- that wraithbone core that runs like a skeleton throughout the immense structure, forming a limbo-like haven for the souls of the craftworld's dead. This is usually protected by the teleporting, psycho-crystalline creatures known as Warp Spiders from whom the Aspect Warriors took their own name, yet the daemon infestation spread by the Masque was so severe even they could not hold it at bay.The craftworld groaned like the living thing that it was, a terrible screaming haunting the cusp of hearing as the Daemonette host devoured the spirits of Biel-Tan's ancient dead from within.As battles broke out between daemon invaders and Asuryani defenders, rivers of hot blood ran between the spires and colonnades of the world-ship's many domes. With Meliniel's forewarning and the Phoenix Lord Jain Zar leading the counterattack, the Daemons of Khorne and Slaanesh had been efficiently quarantined, then banished to the Warp with ruthless efficiency. There was no celebration, no voices raised in jubilation as each new section of the craftworld was declared clear. The world-ship had been infested, and the most dire consequences would likely follow.It was into this unfolding tragedy that Yvraine and her companions arrived. Led by the Solitaire from the Webway gate that Farseer Lathriel had begun to seal once more, they were held at spearpoint by an Aspect Shrine of Shining Spears before being led to the craftworld's Seer Council. The newcomers were Eldar, that much was obvious, but they had with them those who wore the armour of Commorragh, seat of the Craftworld Eldar's ancient foes. In the wake of a daemonic invasion, the Biel-Tani were loath to welcome more potential enemies into their domain.Only when a knot of Daemonettes sprinted from the shadows of a ruined theatre did the fates show their true hand. Lathriel's warriors scythed down the first wave of daemon invaders, but the Slaaneshi creatures were fast, and hell-bent on reaching Yvraine.Many Biel-Tani fell to slashing talons and gouging blades before the Daughter of Shades stretched out her arms, her body glowing with the power of souls from beyond. She gave a great sigh, grey mist pouring from her mouth to wind around every fiend in the great chamber. There came a horrible keening, as if a thousand ghosts gave voice to their anguish at once -- and when the mist had cleared, thedaemons were gone.The resultant parley was strained, but welcome on both sides. Lathriel dimly remembered watching Yvraine dance during her childhood; she was taken aback to recognise her after the passing of so many cycles. And yet, she was unsettling now -- not only in the strange company she kept, but in her eyes and manner of speech. There was no time to investigate further, however, for the craftworld was upon the brink of calamity.Under Lathriel's stewardship, Yvraine and her vanguard were hurried to the Dome of Seeing. They were to take part in an emergency council.The debate was already raging. With the daemons defeated, the Spiritseers were doing everything in their power to siphon untainted souls from the catastrophically-damaged Infinity Circuit and install them into wraith-constructs by way of salvation. But they were few, and the daemon intruders many. Even as they worked, the wraithbone skeleton of the craftworld was crumbling and turning to grey ash. If this hideous metaphysical transformation continued, the craftworld itself would slowly fall apart. Something had to bedone -- something drastic.When Yvraine spoke up unheralded, there was a great clamour amongst the great and the good of the craftworld. Who was she to return to Biel-Tan unannounced after forsaking their ways? Why did she bring the murderous warriors of the Dark City to their door, claiming to know the truth of their mutual destiny? The Autarchs had little time for Yvraine, no matter her pedigree.When Lathriel spoke in her defence, however, all ears turned to listen. Perhaps, said the Farseer, the returned wanderer was more than she seemed. She had banished the daemons of Slaanesh with the same ease that another Eldar might exhale a weary sigh. Perhaps she was the Opener of the Seventh Way, as spoken of in prophecy by Kysaduras the Anchorite -- nemesis of She Who Thirsts, who weaves the skeins at the dawn of the Rhana Dandra.The hush that fell over the assembled masses at Lathriel's words was intense. The atmosphere held in equal parts hatred, fear, confusion and hope. Only a few of those present dared to believe that perhaps their dying craftworld could travel that thin strand of fate that led to the true rebirth of the Eldar race.Then came Jain Zar, her blade still dripping with daemonic ichor. Armoured boots clacking on wraithbone, she strode to the centre of the dome, and held court in a voice both clear and true."This one speaks with many voices. She is our salvation. Listen well."
