Iyanden - Light in the Darkness: The story of Iyanden echoes that of the Aeldari race itself. It is a tale of greatness squandered through hubris, of valour subverted by arrogance and, perhaps, of a renaissance of glory yet to come.It is a story that began with the Fall of the Aeldari -- the dying days of the Aeldari Empire, when Slaanesh's monstrous birth shattered their civilisation, and the survivors fled in disarray across the stars. Having barely survived the catastrophe, the Aeldari of Iyanden did not long despair. Disaster fanned the flames of their arrogance where it had doused them in others.Those who had survived the Fall had done so precisely because they had never succumbed to corruption, or so the Aeldari of Iyanden said, and it was their duty to rebuild. In these early days of Slaanesh's existence, some on Iyanden's council even ventured opinion that the Dark Prince was an enemy that could be overcome, given time and the proper weapons.Though this ideology quickly faded when the scars Slaanesh left upon the Aeldari psyche failed to heal, the dream of rebuilding the empire of the past never did.Thus did the Seers of Iyanden harness ancient techniques of mysticism and science to recover the first Spirit Stones from the Crone Worlds, and soon thereafter adapted the Infinity Circuit of their craftworld to be a conduit for the souls of the dead. Though Slaanesh's shadow could not be truly denied, the Dark Prince would at least have to work harder for its prizes in the years that followed.It was a small victory, but against a nemesis of such terrifying and indescribable power, there would only ever be small victories. And if a god could be thus thwarted, the Iyanden Aeldari reasoned, then why could mortal foes not be similarly humbled?Driven by pride, Iyanden resolved to rebuild, not the Aeldari Empire of old, for that was long lost to them, but a new realm from which they would one day rule the galaxy once again. However, for this to be possible, the agents of Chaos would have to be banished from the galaxy.Deeming this noble goal could be more swiftly achieved though unity of purpose, Iyanden sent emissaries through the Webway to other craftworlds. They shared with them the discoveries of the Spirit Stone and Infinity Circuit, and bade them join in their great work.Iyanden's Seers soon lamented, for though their discoveries were welcomed, their call to action fell upon deaf ears or encountered minds too closed to embrace the opportunity. Many craftworlds deemed their resources just barely sufficient to ensure their survival in a hostile galaxy, and would not indulge such grandiose plans.Other craftworlds -- Alaitoc and Ulthwé foremost amongst them -- claimed higher duties, ones that required them to focus their strength on the destruction of ancient enemies rather than rebuilding their own past. In the end, only the Asuryani of Biel-Tan joined Iyanden's cause.For thousands of Terran years, Iyanden and Biel-Tan fought as inseparable allies, their distant craftworlds united by the common goal of defeating Chaos. Though the Asuryani force was few, when considered on a galactic scale, their mastery of the Webway allowed their fleets and warhosts to span the stars with a speed and surety no other race could ever have hoped to match.As Biel-Tan purged the western galactic arm, so did Iyanden drive the forces of Chaos from the eastern rim, tirelessly defending the Exodites and Maiden Worlds they hoped would one day form the heart of a new Aeldari civilisation.Then came the Tyranids. Iyanden had encountered such creatures before, but those had only been tendrils of the Hive Mind's awareness, groping blindly through space; now Iyanden stood exposed before the onset of an entire hive fleet.In their pride, the Asuryani of Iyanden underestimated the threat. They believed that their might could weather even this storm, that their armies and fleets could vanquish the Great Devourer. Alas, they were terribly wrong.In an eye blink, as the EAeldari reckon existence, the Iyanden craftworld was reduced to ruin. The craftworld's armies and fleets were all but gone, destroyed by the relentless Tyranid advance. Countless billions were slain, whole families and bloodlines lost forever; the living were outnumbered many times over by the dead.Now Iyanden, whose people once dreamed of ancient glory restored, was left all but adrift upon the solar tides. Abandoned by Biel-Tan, whose own dream of an empire reborn suffers not stragglers, Iyanden's living looked to their dead for salvation; the Infinity Circuit had become the craftworld's only hope.Roused from their dreamless slumbers and interred within mighty wraithbone bodies, the spirits of the past must fight for Iyanden's future, and for its very survival.
