Goblins, traditionally, have taken a neutral role in World of Warcraft. Squat, green and a little grotesque, these creatures are mostly mercenaries and merchants -- members of cartels who run airships, oversee cross-faction auctions, and (on occasion) take up arms if the money is right. If there's a dime to be made, Goblins are there. That means they can be found across Azeroth's two continents. In role-playing parlance, they're NPCs (non-player-characters), robots who sell goods or hand out quests.

The Worgen, on the other hand, aren't quite so ubiquitous. Ensconced in the gloomy forests of Silverpine, Ashenvale and later discovered lurking in the wooded Grizzly Hills of Northrend, these wolf-men have always been thought to be irredeemably evil. They're just one of a jillion creatures to be slain in Azeroth, enemies who attack the weak on sight.
