Ynnari - Era of the Dathedian: The events at the close of the 41st Millennium saw the galaxy all but split in half by the celestial cataclysm the Aeldari call the Dathedian.It brought with it a rise in aetheric phenomena -- and being part of a psychic race, the Ynnari were profoundly affected.The Cicatrix Maledictum, that great tear across the fabric of space and time, has further divided the Aeldari people. After the birth of the Great Rift, the Asuryani sent out psychic communiques to every one of their craftworlds, taking stock of the sheer scale of the disaster that had befallenthem.Two of their number did not respond, their psychic traces dwindling with every passing night. Though to an empire as large as the Imperium of Man this would have been considered acceptable losses, for it counts a million worlds and more in its number, for the Aeldari it was a cost so high it wrenched at the heart.To lose two entire craftworlds was a bitter pill indeed. Perhaps one day they would return, just as Craftworld Altansar was drawn from the gullet of the Warp by the odyssey of the Phoenix Lord Maugan Ra. But for now, those craftworlds were gone. Whether their spirits enriched the growing gestalt of Ynnead, none save the Whispering God himself know.Far from uniting the survivors against the common enemy of Chaos as Yvraine had hoped, the rift between the space-going nations of the Aeldari grew all the wider. Their scattered craftworlds are not Warp-capable, for the Aeldari would never risk their souls by willingly braving the hellish dimension of the Empyrean.To do so would be tantamount to suicide, for it would court the hellish attention of Slaanesh, "She Who Thirsts," that entity which prizes Aeldari souls over all others. Neither can the Asuryani craftworlds traverse the Webway, that alien labyrinth dimension between the Warp and realspace through which smaller Aeldari voidcraft traverse the galaxy's hidden paths.Even the smallest of the Asuryani craftworlds is the size of a minor moon, and there are few if any Webway gates large enough to accommodate them. The Harlequins still use secret ways within the Webway for the Aeldari to slide through the vast reaches of space in relative safety, and those who have converted to the Ynnari cause guide Yvraine and her growing congregation through the labyrinth dimension whenever they can.But the coming of these ruinous times have rendered even the quietest space lanes fraught with peril. The Aeldari have become a people truly divided, and in so being, court a new fall.In the cultural hearts of the Aeldari Empire, the wound of the Great Rift -- or the Dathedian in the Aeldari Lexicon -- festered and ran deep.No civilisation of the galaxy could look upon a night sky mauled by the energies of Chaos and not feel affected by it. To a species as sensitive to psychic phenomena as the Aeldari, the scar in the heavens was a constant dull ache in the mind, a reminder of all they had lost.Perhaps it would never have existed at all were it not for the formation of the Eye of Terror, born from the sickening cataclysm of Slaanesh's birth. That stark reminder of their darkest hour gnawed at the mind, making Yvraine's claims of another god yet to be born -- though this time as a saviour -- ring hollow.Across the galaxy, nightmares of guilt and doubt wracked the Aeldari. Even the callous and self-serving Drukhari were affected, forced to admit their way of life was under dire threat. A new era of war began as the turmoil within was turned into merciless strikes against ancient enemies, new foes, and former allies.Much of the blame for the new disaster was put at the door of the mysterious death cult known as the Ynnari, especially upon Biel-Tan. There, the populace had been divided between fervent support for Yvraine and the outright condemnation that followed her visitation -- coinciding, as it did, with the daemonic invasion and subsequent fracture of the craftworld's Infinity Circuit during the Battle of Biel-Tan.Yet the new era brought hope, too -- a new strand of fate that some believed would lead to the Aeldari rising to greatness once more. The being that Yvraine summoned from within Biel-Tan's broken wraithbone skeleton was an Avatar, of a sort -- and for an Avatar to exist, a god had to have risen in power in the Warp for it to incarnate.The entity known as the Yncarne was proof that the Whispering God was real, and hence that he could perhaps save their souls from She Who Thirsts once and for all.
