Dark Eldar are the evil kindred of the Eldar. They prowl the galaxy as pirates, slavers, torturers and mercenaries. The Dark Eldar emerged after the Cataclysm, the fall of the Eldar brought about by their hedonism which created a vast Warp Rift, and manifested the Chaos god Slaanesh. Most Eldar souls were consumed by Slaanesh in the Cataclysm. The Dark Eldar escaped this fate by following his lead and consuming the anguished souls around them. This strengthened them, and allowed them to cheat death. Now they thrive on murder and pain, their desire for sadism never sated, ensuring their immortality.
