A knight before the Round Table was formed, Sir Balin lives only for a few weeks following his release from King Arthur's prison and his subsequent slaying of a Lady of the Lake. Just prior to his departure, his destiny is sealed by the arrival of a mysterious damsel bearing a sword that only the "most virtuous" knight in Arthur's court will be able to draw; Balin draws this sword easily. His adventures end when Balin and his brother Balan destroy each other in single combat, fulfilling an earlier prophecy about the destiny of the bearer of the damsel's sword.
