Haemonculi - Age of Dark Genesis: Rulers of the Stars (ca. M15-M20) - Those Aeldari who would become the first Haemonculi are the masters of the ancient Aeldari Empire. Powerful beyond the dreams of mortals, they hold dominion over the stars themselves. Worlds live or die at their whim, and suns are born and quenched under their command.Shadows in the Twilight (ca. M18) - With the other intelligent species of the galaxy posing little threat, currents of complacency begin to flow throughout Aeldari society. A new paradigm of self-indulgence begins to rise. The Aeldari turn to ever more capricious acts in order to fill their long lifespans with excitement. Many become addicted to the finest sensations their empire can provide. As the Terran centuries slide past, cults of decadence thrive in lawless port-cities of the Labyrinth Dimension of the Webway -- Commorragh foremost amongst them.Faith Bled Dry (ca. M19-M24) - The worship of the Aeldari gods fades as the Aeldari indulge their obsessions at all costs. Obeisance is instead paid to the Dark Muses, figures synonymous with unrepentant vice. New depths of depravity are plumbed inside the realm of the Webway and without. Those Aeldari who will become the Haemonculi are central to each new orgy of experience. These shadowy figures grow daily in power and influence among the cults of pleasure, feasting on ever more esoteric banquets of sin. The worst of their number begin to change, body and soul, though for now their corruption is hidden behind fine words and ethereal beauty.Devils in the Darkness (ca. M25-M30) - The core of Aeldari society becomes infected by the spiritual malaise. Some have mixed feelings about the direction their society has taken, whilst others -- the forefathers of the Haemonculus covens amongst them -- are utterly unrepentant. As the lines between unbridled experience and outright evil are blurred, the rich Aeldari emotions seeping into the Warp begin to coalesce. The more puritanical of the Aeldari, horrified by the degeneration of their society into decadence, hedonism and corruption, flee their ancient homeworlds in an attempt to escape the imminent catastrophe, becoming the first Exodites and Craftworld Aeldari.Fall of the Aeldari (ca. M30-M31) - The psychic tempest the Aeldari are unwittingly stirring in the Warp reaches a stormy climax, and a new Chaos God is born. With a soul-shattering scream of triumph, She Who Thirsts rips her way into existence. The heart of the Aeldari Empire is torn out by Slaanesh's birth, annihilating almost all of the Aeldari race and leaving a sector-wide wound in reality in its place. Only those Aeldari who had fled to the fringes of the galaxy survive. Even those hidden in the port-cities of the Webway pay a terrible price.Rise of Commorragh (ca. M31-M32) - Despite the aching void that now blights their souls, the Aeldari controlling the sovereign realms of the Webway, the Drukhari, amass ever more power. One city in particular, the mighty Commorragh, grows strong upon the carrion of the old empire. As the multi-dimensional metropolis becomes ever more influential, it subsumes many lesser Aeldari port-cities within the Webway until its preeminence is beyond doubt. The Dark City grows at an exponential rate, and countless factions and dynasties build ever more impressive monuments to their own prowess. The true architects of the city-realm's supremacy, hidden from sight by the vaunting ambition of those who claim to rule, withdraw to haunt its lowest levels. The underspires of Commorragh grow like stalactites beneath its impossible reaches, and within them the Haemonculus covens are born.
