Worgen is a race of “feral wolf-beasts” which make their debut on the newest update to the World of WarCraft: Cataclysm game, which is currently on a pre-order. The race of the Worgen, for the Alliance, are a new addition of what many call on to be the werewolves of the game, although they are not directly called werewolves.
“The worgen’s first verified appearance in the Eastern Kingdoms has been traced back to the Third War, when the archmage Arugal utilized the wolf-beasts as a weapon against the Scourge. Arugal’s weapons soon turned against him, however, as the curse of the worgen rapidly spread among the human population, transforming ordinary men and women into ravenous, feral creatures.”…”Many believe that a treatment for the worgen curse may exist, although others have nearly given up, fearful that if the barricades should fall, their humanity will be lost forever.” (Excerpt ref: World of Warcraft official site)
Currently the World of Warcraft game refers to the Worgen as being cursed from an unknown source and spreading the “pandemic” among many of it’s population. But the origins and the cure for the new race are currently unknown.
