Background

The Dark Eldar or Eldarith Ynneas in the Eldar Lexicon are the forsaken and corrupt kindred of the Eldar, an ancient and highly advanced alien race of fey Xenos. Their armies, like their Eldar counterparts, usually have the advantages of mobility and advanced technology, though they are often lacking in resilience and numbers. The Dark Eldar revel in piracy, enslavement and torture, and are sadistic in the extreme.

Dark Eldar 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 interdimensional labyrinth known as the Webway to traverse the galaxy safely and far more quickly than most advanced races are able to with their Warp jumps. The Dark Eldar are unique amongst the intelligent races of the Milky Way Galaxy because they do not live on a settled world or worlds, 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 are mainly 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, though they are sometimes used as mercenaries by other species.

The Dark Eldar have been sighted in the Koronus Expanse, leading many to assume that somewhere in the Expanse is an outpost where they engage in their sadistic recreations. To date, this location has not been found, but many in Battlefleet Koronus would love to purge the filth of these Xenos from the stars.
