B-Stz was a Luminoth, the first known Guardian of Torvus Temple, and a great hero of Torvus during the Aether Incident. He led the charge of the Fourth Battle of Torvus and killed the Ing Horde war chief in the battle single-handedly. He lived to die peacefully of old age, and a statue honouring him can be seen at the entrance to the Torvus Energy Controller.
