Aeldari - Drukhari: In the wake of the Fall, the ancient Aeldari civilisation was reduced to a broken diaspora, their empire destroyed by the aftershock of Slaanesh's inception. Yet those adherents of the pleasure cults hidden in the settlements within the Webway remained all but untouched, protected by the nature of the Webway's substance from the soul thirst of the newborn Chaos God.Great swathes of the labyrinth dimension itself were shattered into ruin, but many of those Aeldari who had built personal empires in and around Commorragh survived the birth of Slaanesh. The echoes of the new god's arrival had wrought insidious changes within them -- changes whose horrific nature would not be fully comprehended until later -- but the Commorrite Aeldari had escaped destruction.In their supreme arrogance they did not cease their quest for excess or pleasure, even for a moment. Repentance and atonement were alien concepts to a people who acknowledged no limits to their power.The Aeldari sealed within the Webway had not escaped the Fall, though this horror would only dawn on them slowly. Rather than having their essence consumed in one great draught, their souls were slowly draining away into the Warp -- consumed over time by Slaanesh rather than all at once.Where the Craftworld Aeldari learned to deny Slaanesh's hold upon them using the mystical Spirit Stones and Infinity Circuits as well as the strictures of the Asuryani Path to deny the pull of their darker impulses, the Commorrite Aeldari became expert at ensuring that lesser intelligent 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 psychic agony of others nourished their withered souls and kept them vital and strong, filling their frames with unnatural energies. Assuming they could feed regularly enough, the Webway dwellers became physically immune to the passage of time, thus using this parasitic immortality to hold off their deaths indefinitely.So it was that the Drukhari were born, sadistic, psychic parasites who subsist upon the anguish of others in order to prevent the slow death of their immortal souls. Ten thousand Terran years later, in the 41st Millennium, Slaanesh's thirst pulls at them still. There truly is no escape. The Drukhari have unwittingly doomed themselves, exchanging a horrific but mercifully swift end for an eternity of ghoulish starvation.To this day the Drukhari raid the galaxy from the canker upon Creation that is Commorragh, sowing misery and destruction wherever they emerge and spiriting away countless captives to their lairs for their own horrible ends. They are masters of torture and degradation, for the longer a Drukhari can drag out the punishment and agony of a captive of any sentient race, the greater the psychic nourishment that can be derived from it.A Drukhari who has recently fed upon the torment of others shines with a cold and startling aura, their physical form restored to perfection even as the spirit within festers. One who is starved of such energies for long enough will become a shadow, desperately hunting for a taste of pain with which to stave off the gnawing pangs in the depths of their soul.The Drukhari possess no psykers among their people despite possessing the same innate psychic potential as other Aeldari; even within the protective confines of the Webway, the threat of drawing the attention of Slaanesh to the mind of a potent psyker is simply too great to risk.
