The Eldar in general consist of five distinct sides: the Craftworld Eldar (often simply called Eldar), who are similar to the High Elves; the Drukhari, who are similar to the Dark Elves; the Exodites, who are similar to the Wood Elves; the Harlequins, servants of Cegorach, the Laughing God; and the Ynnari, a new faction of the Eldar that worship the god Ynnead. These equivalences are only in very general thematic terms, however, as the major details of the races' backgrounds differ greatly from their "Warhammer Fantasy" counterparts. For instance while the Dark Elves have long existed as the main antagonist to the High Elves in "Warhammer Fantasy", Games Workshop originally incorporated both High and Dark Elves' elements into the Craftworld Eldar for the "Warhammer 40,000" universe. Only recently in 1998, did they create the Dark Eldar as a separate army, and there is little back-story on the Eldar-versus-Dark Eldar rivalry. The Exodites exist mainly in "Warhammer 40,000" background material and never had any specific models or dedicated army books for use in the tabletop game, however the Alaitoc Craftworld Eldar is closely linked with the Exodites.
