Furbolgs are ursine humanoids. They reside in tribes, and were peaceful allies of the Night Elves until the coming of the Burning Legion, when many were affected by the corruption they brought and turned evil. The Timbermaw tribe were supposedly the only tribe to escape the corruption. Their tribe now has been forced into hostility due to an increasing show of violence towards them, as many assume they are also corrupted. Around 10,000 years before Warcraft: Orcs and Humans the Furbolg race fought the Burning Legion alongside the Night Elves, Tauren and Earthen. The Ursa Warriors are the Furbolg elites.

Other tribes than the Timbermaw include the Blackwood tribe, Stillpine tribe, and Deadwood tribe. These names were probably made after the Furbolgs in the tribes became corrupted.
