Webway - Dark City: As the ancient Aeldari fell into decadence and depravity, amongst the pleasure-seekers and the interminably curious were those whose pursuit of excess became ever more extreme. These included a great proportion of the aristocracy of ancient Aeldari society; those with the wealth and the time to truly explore every aspect of decadence.One by one, the leaders of the hedonistic cults of excess that were taking over Aeldari society became obsessed with their own power. They relocated into the Labyrinth Dimension known as the Webway, taking over hidden ports and setting up strongholds at key nodal points within which to continue their debased pursuits.Almost invariably, these realms were linked via portals to the sprawling and exhilaratingly lawless city of Commorragh. Commorragh was originally the greatest of the Webway port-cities, impossibly vast and able to transport a fleet to any of the most vital planets of the Aeldari Empire by virtue of its many portals.Because of the access it granted to the far-flung corners of realspace, this mighty metropolis was reckoned to be the most important location in the entire Webway. It was too valuable to the Aeldari as a whole to belong to any single aspect of their interstellar empire, so it existed outside the jurisdiction of the great Aeldari councils of that time. Precisely because of its autonomy, the city-port quickly became a magnet for those that wished their deeds to remain hidden from prying eyes.The Aeldari sealed within the Webway had not escaped the Fall of the Aeldari untouched. Rather than having their essence consumed in one great draught, their souls were slowly draining away into the Warp -- consumed over time by "She Who Thirsts." The Aeldari fear Slaanesh above all, for it was given life by their actions, and yet waits hungrily on the other side of the veil to claim each and every one of them.Whereas the Aeldari of the craftworlds learned to deny Slaanesh's hold upon them using the mystical Spirit Stones and Infinity Circuits, the Commorrite Aeldari became expert at ensuring that lesser beings suffered in their stead. Provided they steeped themselves in the most extreme and decadent acts, the Aeldari of the Webway found that the curse of Slaanesh could be abated.The absorbed psychic emanations of agony drawn from other sentient beings nourished their withered souls and kept them vital and strong, filling their frames with unnatural energies. Assuming they could feed regularly enough on the psychic pain of other sentient beings, the Aeldari of the Webway became physically immune to the passage of time. So it was that the Drukhari or "Dark Ones," were born, a race of sadistic parasites who subsist upon the anguish of others in order to prevent the slow death of their immortal souls.To this day the Drukhari raid the galaxy from the canker that is Commorragh, sowing misery and destruction and spiriting away countless captives to their lairs for their own horrible ends. Commorragh appears within the Webway to be a composite urban centre on an impossibly vast scale, a hazy, contradictory realm whose dimensions can overawe the sanity of any who approach it. Thousands of starships dock each day at its spires, for the Drukhari are a far more numerous species than the Imperium of Man, or even their own craftworld Asuryani kin, fully suspect.Yet Commorragh plays host to more than just the Drukhari kindred of the Aeldari. Many diverse species of alien mercenaries, bounty hunters and even Human Renegades all risk their souls to do business in Commorragh, hoping to claim just some of the riches to be had in the Dark City.
