Sua crueldade é um modo de EVITAR o caos - já que eles não têm pedras espirituais, que protegem suas almas, ao invés disso sacrificam almas dos outros. É um pouco paradoxal: eles fazem o trabalho do caos enquanto desprezam ao mesmo tempo; eles fazem o que Slaanesh cultist faz, mas ao mesmo tempo os desprezam e odeiam a She Who Thirsts por destruir seu antigo império. Se você preferir usar o sistema de alinhamento Warhammer Fantasy RP, eles são MALES ao contrário dos cultistas CHAOTIC.The Dark Eldar are the living embodiments of all that is wanton and cruel in the Eldar character. Highly intelligent and devious to the point of obsession, these piratical people revel in the physical and emotional pain of others, for feeding upon the psychic residue of suffering is the only way they can stave off the slow consumption by the Chaos God Slaanesh of their own souls.

This region of damaged tunnels is centred across the Warp Storm known as the Screaming Vortex. The Vortex is home to teeming hordes of daemon-worshippers and mutants, living and dying at the whims of warlords and sorcerers intent on murder and subjugation in the name of their dark gods. While this a ready source of slaves and victims for the raids of the region's Kabals, it is a realm largely inhospitable to the Dark Eldar, so strong is the presence of She Who Thirsts within the storm
Significa que a mera presença do caos enfraquece os Eldars das Trevas.
