Webway - Fall of the Aeldari: The Webway was created by the Old Ones, an ancient and technologically advanced intelligent species who established an interstellar empire across the galaxy tens of millions of standard years before the development of most of the other self-aware species. They created the Webway as a conduit that allowed its masters to travel at will to countless far-flung worlds without risking the fickle tides of the Warp.The ancient Aeldari were taught about this arcane technology by the Old Ones, and quickly mastered the Labyrinth Dimension of the Webway, expanding their realms into the furthest corners of reality where they learned much about the universe that has since been forgotten. Over the millennia, the core of the Aeldari species began to look inwards, inexorably seeking new ways to explore the full range of emotion and sensation which they felt so powerfully.A sickness of vice overtook the Aeldari, and blood flowed through the streets of the worlds of the Aeldari Empire amidst the bestial roar of the crowd. Their hidden realms within the Webway became sprawling palaces of avarice and sadism, and entire worlds were bent to the pursuit of the darkest of sensations. As the moral corruption of the Aeldari tightened its stranglehold, echoes of ecstasy and agony began to ripple through time and space.In the parallel dimension of the Immaterium, the reflections of these intense experiences began to coalesce, for the shifting psychic tides of the Empyrean can take form around intense emotion felt by large masses of sentient beings. Slowly, silently, a nascent god of excess grew strong in the depths of the Warp.Within the Warp, thoughts and emotions flow together, fed by fellow feelings until they achieve a consciousness of sorts. They become entities of greater or lesser potency depending on the intensity of their origin. Amidst the swirling psychic energy of the Empyrean, the corruption of the decadent Aeldari became manifest on a horrifying scale as the flood of raw emotions coalesced into a gestalt consciousness. Slowly, the Great Enemy stirred towards wakefulness.Too late, the Aeldari realised that they had created a god in their own hideous image, a god grown immense and potent by suckling upon the dark fodder of the collective Aeldari soul. No creature was ever conceived that was as terrible or perverse as the Chaos God Slaanesh.It is a name the Aeldari will not speak, instead whispering Sai'lanthresh, translatable from the Aeldari Lexicon as "She Who Thirsts." In a heartbeat, the shining Aeldari civilisation that had lasted for aeons had its heart ripped out, leaving a pulsing afterbirth of pure Chaos in its place.Since the Fall of the Aeldari in the late 29th and early 30th Millennia of the Imperial Calendar, the Webway has become a realm shattered and dangerous, its splintered reaches infested by strange beings from different realities. Yet the Webway's portals still allow the brave and the bold to strike without warning at millions of locations throughout realspace.The ancient Aeldari discovered millions of Terran years ago the means to move within the threads of the veil between realspace and the Warp. It was they who mastered the original Webway network, though it has changed drastically since the height of the Aeldari Empire, torn open by war and disaster. Moving between the dimensions is a technique fraught with danger, but such is the skill and intellect of the Aeldari that they are still able to utilise it without hesitation.The Asuryani craftworlds float in deep space and move at only sub-light speeds. Their exact locations are not known by other intelligent species, and the Craftworld Aeldari themselves do not consider their physical positions in the galaxy to be important -- a minor detail in an eternal journey. Smaller Aeldari spacecraft, moored in docks upon the craftworld's fringes, travel between the different craftworlds by means of the Webway. The main gateways into the Webway take the form of swirling spheres of light and darkness held in stasis astern of each craftworld.The pathways of the Webway lead to the craftworlds, to the surface of the verdant worlds of the Exodites, to the Drukhari's corrupt city of Commorragh, and to untold thousands of other worlds throughout the galaxy. Cloistered deep within the hidden city-realms of the Webway, those survivors who concealed themselves in their palaces of depravity still revel in the debauched lifestyle that led to the Fall of the Aeldari.In that twilight realm between the material universe and the Warp, the Drukhari mock and jeer those ravaged by the downfall of their species. Even though they would never admit it, they know in their hearts that, try as they might to allay their fate, unless something changes beyond their imagination to conceive, Slaanesh will claim them in the end.
