Balin /ˈbeɪlɪn/ the Savage, also known as the Knight with the Two Swords, is a character in the Arthurian legend. Like Galahad, Balin is a late addition to the medieval Arthurian world. His story, as told by Thomas Malory in Le Morte d'Arthur, is based upon that told in the continuation of the second book of the Post-Vulgate cycle of legend, the Suite du Merlin.
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 Sir Balan destroy each other in single combat, fulfilling an earlier prophecy about the destiny of the bearer of the damsel's sword.
Prior to his tragic end, this ill-fated knight contrives to inflict a "Dolorous Stroke" with the Holy Lance, the spear that pierced Christ upon the Cross, thus setting the scene for the Post-Vulgate version of the search for the Holy Grail. Merlin tells Arthur that had he lived, Balin would have been the best and bravest knight.
