Worgen are one of the two new playable races that will be available in the World of Warcraft: Cataclysm expansion. They have the outward appearance of werewolves; lupine figures that walk on two legs. Worgen players are in fact former humans that have been infected by an ancient and malignant curse.

Long ago the Druids of the Scythe, a faction of the Night Elves, shapeshifted into Worgen. The transformation into these violent beasts eventually caused them to lose their minds and they were locked away by the other Druids. Their curse that transformed anyone that suffered their bite into one of them was locked away with them.
