Dark Eldar: The Dark Eldar are the forsaken and corrupt kindred of the Eldar, an ancient and highly advanced alien race of fey humanoids. Their armies like their Eldar counterparts, usually have the advantages of mobility and advanced technology, though they are often quite lacking in resilience and numbers. The Dark Eldar revel in piracy, enslavement and torture, and are sadistic in the extreme. The Dark Eldar's armies make use of various anti-gravity skimmers such as Raiders and Ravagers to launch high speed attacks. They strike with little or no warning, using an inter-dimensional labyrinth known as the Webway to traverse the galaxy safely and far more quickly than most advanced races are able to. The Dark Eldar are unique amongst the intelligent races of the milky way galaxy because they do not live on a settled world(s), but rather the bulk of their population is concentrated in one foul city-state (the Dark City of Commorragh) that lies within the "Ordered" Immaterium of the Eldar Webway. The dark Eldar mainly consist of pirates and slavers who prey on targets across the galaxy to feed their unholy appetites for other sentient beings' souls, a terrible desire called "The Thirst". However they are sometimes used as mercenaries by other species.
