Drukhari - Dark Eldar || Warhammer 40K Lore
32The Drukhari or Dark Eldar are kindred to the Asuryani and other Aeldari, an ancient and advanced race of elf-like humanoids. Their armies usually have the advantages of speed and 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 raiding parties use advanced anti-gravity skimmers to launch high-speed raids on their enemy while still transporting many of their warriors. Due to their use of the galaxy-spanning inter-dimensional labyrinth known as the Webway, they are extremely mobile, striking from seemingly nowhere, with little or no warning, and vanishing with their captives before a significant military reaction can be mobilized.
