A playable Alliance race added to World of Warcraft with the release of the Burning Crusade expansion
pack.
In the lore, they were purged from their homeworld of Draenor by the Burning Legion, and again from Outlands by the orcs (once their allies) that eventually became corrupt by fel magics of the Legion. In a desperate attempt to survive and combat the Legion, they took control of a portion of the Tempest Keep, using it as a spacecraft to settle on another new planet.
This planet was earth, and with a
crash-landing on the Kalimadorian Azuremyst Isle, they quicky settled and sought relations with the Alliance. In no
time, they became a new part of it, and began taking steps to
re-establish their civilization and combat the Legion.
The Draenei race is an enlightened one- like the many generations of
Humans, High-Elves, etc., a major focus of theirs is the Holy
Light and, as a newer concept, the Naaru (which is a race of
god-like entities that supposedly create the
Light). Many years prior to their purging from Draenor, the Naaru made a pact with the Draenei to unite them with the many enlightened races of the universe to form the
Army of
Light, which would bring down the Legion and all related darkness.
The races available to Draenei are: Warrior, Paladin, Shaman, Mage,
Hunter, and Priest. The Draenei are the first of the Alliance that can practice shamanism, although that this practice is often reputed by the other races (save for the Night-Elves and Gnomes, who
haven't indicated a particular view).
