The Eldar once ruled a vast inter-galactic empire. They are more advanced than humans in every way. It was this superiority, however, that led to their downfall. As rulers of the galaxy, the Eldar were tremendously hedonistic, dedicated wholly to the pursuit of pleasure. Their activities created a disturbance in the Warp, manifesting in a new Chaos god, Slaanesh. When Slaanesh emerged, he consumed almost all the Eldar souls and ripped apart their empire in an event known as the Cataclysm. Today, the once proud Eldar are refugees, scattered across the galaxy. Their armies are still formidable and proud, but now they must fight for survival against increasing enemies.
