"We owe the Eldar a great debt of gratitude. If it were not for their voices, we could not have our choir. If it were not for their chisels, we would not have our blades. Remember to thank them when you run them through."
- —Andrada, the Gore-Diva
The Fall of the Aeldari is the name for the terrible catastrophe that befell the Aeldari race early in the 30th Millennium of the Terran calendar and ended their domination of the Milky Way Galaxy after millions of standard years, leading to the birth of the Chaos God Slaanesh and the emergence of the present-day Aeldari factions including the Craftworld Aeldari, also called the Asuryani, the Drukhari and the rustic Exodites.
Ancient and mysterious, the Aeldari are enigmatic humanoid aliens who never speak openly of their terrible past. Before Mankind had even begun to walk upright, the Aeldari Empire spanned the galaxy. Their whims decided the fate of worlds and quenched the fiercest suns. Now, they are all but extinct -- the last fragments of a shattered civilisation plunged into constant warfare. They have been reduced to a scattered and nomadic race, as those who had retained enough sanity to flee before the Fall did so on mighty vessels called Craftworlds. It is on these worldships that the last remnants of the ancient Aeldari civilisation now drift amongst the stars.
The Aeldari will not describe their downfall to any member of a "lesser race," but much of the story can be gleaned from fragmented sources. The Aeldari succumbed to extremes of experience, their senses so finely attuned they perceived the heights and depths of agony and ecstasy. Throughout a long period of decline, the intensity of emotion generated by the Aeldari's excess began to coalesce within the Immaterium. A new Chaos power was being formed, growing stronger with every indulgence. This entity dozed fitfully, its dreams fed by the Aeldari's deeds. These dreams leaked back to the Aeldari psyche and the race plunged into further extremes.
In time, the Aeldari people sank to the lowest depths of depravity and the sleeping power awoke. The Chaos God Slaanesh was born and its birth cries decimated the race, drawing the spirits of billions of Aeldari into the Warp to be consumed by the newborn god. The worst destruction occurred at the heart of their galaxy-spanning empire, where the Warp erupted into realspace. An area almost twenty thousand light years across was engulfed in the very stuff of Chaos, known today as the Eye of Terror. The Eye is an area of Warp/realspace interface -- a vast, open wound upon the very fabric of reality constantly weeping filth and corruption.
The Eye of Terror is now home to the darkest evils of the galaxy. At the height of the Horus Heresy in the early 31st Millennium the Chaos Space Marine Traitor Legions were driven from Terra and naturally sought shelter within the Realm of Chaos. Some of these corrupted Space Marine Legions claimed new homeworlds, moulding each to their own perverse designs. The followers of the different Ruinous Powers now fight one another in an eternal struggle for supremacy known as the Great Game for the resources to be found within the Eye of Terror, but they are at their most deadly on the very rare occasions when they cease fighting one another and turn their attentions to the material universe outside the Eye. Few have managed to unite the disparate factions in this manner, but Abaddon the Despoiler, once the chosen lieutenant of Horus, is such a being, moulding the Traitor Legions, mutant armies, and daemon hordes into Black Crusades that pillage and destroy the Imperial sectors around the Eye.
The Eye of Terror, created by the shame of the Aeldari and the price of their Fall, now provides the means by which the Traitor Legions have terrorised the Imperium for ten thousand standard years, as time within that impossible realm is as distorted as it is within the Warp itself. Ten millennia after the events of the Horus Heresy, the very same Traitors who fled from the armies of the Imperium still embark upon their Black Crusades, while the Aeldari mourn for what was lost, and fear that Mankind, the foolish Mon-keigh, will replicate their arrogance --and its terrible consequences for the galaxy -- a thousand-fold.
Decay and Degradation
The Aeldari were a technologically advanced humanoid race, generally considered the most powerful intelligent species in the galaxy before the founding of the Imperium of Man. Their ancient empire spanned the Milky Way Galaxy, and the only intelligent race that could have challenged them, the Necrons, lay in hibernation on their Tomb Worlds across the galaxy in the wake of the end of the War in Heaven. They had unparalleled mastery of the Immaterium, so much so that they could even mold the mystical energies of that hyperdimensional nether realm into physical materials like Wraithbone. When Mankind was still long millennia away from building the Egyptian pyramids, the Aeldari already ruled a vast, unchallengeable interstellar empire. The fall of this empire came not from the actions of another species, but literally from the conflicts that lay within the Aeldari themselves.
Aeldari technology had advanced so far by the height of their empire that little or no work was required by individual Aeldari. As a result, at some point around the 24th or 25th Millennium, groups of Aeldari began forming groups known as Pleasure Cults dedicated to the pursuit of experiencing every sensation, pleasurable or painful, that life had to offer. As the Aeldari's emotions are often more powerful than those experienced by Mankind, they were capable of the dedicated pursuit of sensation in a way that even the most sybaritic members of the human race would find difficult to comprehend. These pursuits became more extreme, hedonistic and depraved as time went on. Torture and murder came to be seen as art forms every bit as worthy as poetry, music and painting. The Aeldari were extremely long-lived (even immortal before the Curse of the Nightbringer), never suffered from senility or disease, and their superior intellects, deep emotional resonance and potent psychic powers allowed them to perfect their skills to a degree far beyond that of even the most talented humans. The Aeldari were able to devise cunning new ways of torturing and killing their fellows at rates never imagined.
Government within the Aeldari empire soon collapsed and the degeneration of their homeworlds and colonies into utter depravity continued unimpeded. As the pursuit of ever more extreme experiences reached its height, death reigned in the streets of Aeldari cities, hunter and hunted each being part of a twisted ritual of destruction which consumed millions of lives. Some Aeldari were able to see that their now-corrupt society was destroying itself, and fled in disgust; these refugees would settle in the distant planetary colonies of their empire and would later be known as the Exodites.
Upon dying, the soul of any sentient deceased being traverses the bounds of the physical realm and goes to rest within the Warp. Generally, this has no effect on the physical realm. The Aeldari, however, are quite different. The psychically-gifted Aeldari have powerful souls and register a much stronger presence in the Warp than do the vast majority of humanity, most of whom possess no psychic abilities.
The deaths of hundreds of thousands of Aeldari in extremely pleasurable and/or painful ways -- and the concomitant entry of huge numbers of their souls into the Warp -- had an unintended, and catastrophic, side-effect: The restless souls of the dead Aeldari caused the formation of terrible Warp Storms, which made interstellar travel extremely difficult in the physical realm (This was one of the factors that precipitated humanity's Age of Strife). A far worse effect, however, was that these souls began to somehow coalesce into a larger entity, a living, psychic embodiment of the corruption that had taken their lives. As more and more Aeldari died to fuel the decadence and depravity of their society, this entity continued to grow, and the Warp storms continued to grow worse.
In the early 30th Millennium, this great Warp entity finally attained full sentience. In the last few years before its birth, many Aeldari were driven insane by the uncontrolled psychic energies possessed by this embryonic entity. Many Aeldari who had stayed behind on their homeworlds to try and turn their race away from the decadence that had consumed them saw what was happening and knew that something terrible was about to occur. These Aeldari left the empire behind, fleeing aboard colossal spacecraft called Craftworlds and taking any plants, animals or other pieces of the Aeldari culture and their homeworlds' environments with them.
At last the entity suddenly came to life, and was said to have "taken its first breath"; this first 'breath' instantly slew the overwhelming majority of the Aeldari who lived in the empire as their souls were 'inhaled' by the entity. The death toll was so massive within the Aeldari empire that Warp energy literally spilled over into the physical realm, creating a permanent interface of realspace and Warpspace later known to the Imperium of Man as the Eye of Terror. Even the Aeldari who had fled their empire were affected -— many Exodites and Craftworlders fell dead as their souls were also sucked from them. As well, many psykers of other races were also driven insane or killed by the power that had been unleashed. This new entity became the fourth major Chaos God, Slaanesh, the Prince of Pleasure, and the Aeldari empire was no more.
The Prince of Chaos
Slaanesh's first act after annihilating so many Aeldari was to hunt down their gods, who also existed in the Warp. As they had with Slaanesh, the psychically-gifted Aeldari had previously created their own pantheon of gods from their collective desires and beliefs' affect upon the energies of Warpspace. With the sudden deaths of so many Aeldari, the old gods were drastically weakened. Slaanesh took advantage of this weakness and destroyed them, assimilating them within itself. Unlike the other intelligent races of the galaxy who see the youngest Chaos God as male, the Aeldari consider Slaanesh to be female, and refer to her as "the Great Enemy" or "She Who Thirsts." Ancient Aeldari Gods, such as Kurnous, Isha, Vaul, and Asuryan were hunted down and consumed by Slaanesh.
However, among the death and destruction, two of the original Aeldari Gods survived. It is said that the Aeldari god of war, Kaela Mensha Khaine, fought Slaanesh, and neither was able to defeat the other — Khaine, being a war god, could not be defeated in battle, but Slaanesh was far too powerful for Khaine to defeat. Some tellings of the story state that in the end, the Chaos Blood God, Khorne, interceded on Khaine's behalf, likely with the aim of absorbing the Aeldari god of war himself. Regardless of the actual events of the battle, the result is clear: Rather than be absorbed by the more powerful Chaos Gods, Khaine's form was shattered and exiled to rest in the mortal realm in the form of great statues called "Avatars", which rest in the hearts of the various Craftworlds, while pieces of Khaine's soul reside in the Infinity Circuit of the Craftworlds and can be called upon in times of emergency to animate the Avatar--though the price is high in blood for this boon.
The other Aeldari god to survive the Fall was the trickster God Cegorach, also called the Laughing God. He is said to have hidden himself behind Khaine during the great duel with Slaanesh; when Khaine was finally banished, the Laughing God hid himself within the labyrinthine confines of the Webway, where he still resides. Occasionally he reenters the Warp in order to play pranks upon Slaanesh, most famously to rescue the souls of certain Harlequins from consumption by it.
After Slaanesh's birth and its war with the Aeldari gods, the few surviving Aeldari found their society in ruins. They were split into factions, and were forced to find ways of protecting themselves from Slaanesh; with Slaanesh's existence so closely tied to the Aeldari race, any Aeldari who subsequently died had his or her soul instantly consumed by the ever-hungry "Great Enemy". The new Aeldari factions -- the Craftworld Aeldari, the Drukhari, the Harlequins, the Aeldari Outcasts, and the Exodites -- each found their own ways of dealing with the curse of Slaanesh.
The Fall of the Aeldari was a major event on the galactic stage. Firstly, the Aeldari empire was extinguished, leaving behind the hell-region called the Eye of Terror that has threatened Aeldari and the Imperium alike for ten thousand standard years. The forces of Chaos gained another powerful patron in the new Chaos God Slaanesh, making the Ruinous Powers a further threat to the existence of mortals; however, Khorne's interference in the Slaanesh-Khaine duel caused a rift between Slaanesh and Khorne, and is one of the reasons why the two gods and their followers continue to be enemies.
The Aeldari went, virtually instantaneously, from being the most powerful force in the galaxy to being a species comprised of a relatively small groups who struggle to survive and preserve their culture. The various Aeldari factions are reviled by other races for their tendency to focus on their own survival, often at the expense of those other races' well-being, and for the treachery and subterfuge they have often employed in this effort.
The birth of Slaanesh had the side-effect of clearing the galaxy of the Warp Storms associated with the era immediately prior to its birth. This allowed interstellar travel and communications to resume; the human leader known as the Emperor of Mankind was able to take advantage of this to unify humanity under his leadership on Terra and Mars, end the Age of Strife, and begin his epic Great Crusade. The Great Crusade would see the forging of the galaxy-spanning Imperium of Man, which would attempt to fill the power vacuum in the galaxy left by the near-annihilation of the Aeldari.
Some Aeldari did learn from their mistakes. Knowing that their psychic prowess has profound effects upon the Warp, some far-sighted leaders among the Craftworld Aeldari, the Asuryani, have noticed the slow growth of a new deity, Ynnead, the Aeldari God of the Dead, within the safe confines of all the Aeldari Craftworlds' Infinity Circuits. The Aeldari hope that if and when Ynnead is finally born, he will confront Slaanesh and defeat it once and for all. But as the great Farseer Eldrad Ulthran has noted, this may take thousands of Terran years at the very least, and Ynnead's awakening will require the passing of every Aeldari soul linked to the Eternal Matrix-effectively destroying the Aeldari's past even as it might guarantee this faded species a new beginning.
