The Stillpine tribe is a tribe of furbolgs inhabiting the Azuremyst Isles. They are led by High Chief Stillpine who can be found at Stillpine Hold. Since the arrival of the Draenei the Stillpine tribe have allied themselves with them and the Alliance. The existence of the Stillpines seems to contradict the point that the Timbermaw tribe was "the last uncorrupted furbolg tribe in the world". However, due to their semi-isolated location, it is possible that the Timbermaws simply were not aware of the Stillpines' existence, or at least not aware of their escape from corruption.
All Stillpine members are tagged as Alliance and will cause Horde players to be flagged for PvP if attacked.
