The Dark Eldar are a faction in the Warhammer 40,000 universe, known for their sadistic and hedonistic nature. They originate from the ancient Eldar race but have chosen a path of cruelty and excess, living in the dark city of Commorragh. Their society is built on raiding and capturing other beings to sustain their own lives, as they are dependent on the suffering of others to avoid a fate worse than death. Dark Eldar warriors are highly skilled and agile, often using advanced technology and weaponry in battle. They employ a variety of units, including Kabalite Warriors, Wyches, and Reavers, each serving different roles in their raids. Their aesthetic is characterized by sleek, dark armor and a focus on speed and precision, making them formidable opponents on the battlefield.
