Sir Justin, the newest member of the Knights of the Round Table in King Arthur's Court, was one of the many knights who had witnessed the death of Queen Guinevere's cousin, Sir Fallon. Fallon revealed his attacker to be the ogre Blunderbore in his last breath. Justin then vowed that he would avenge Fallon's death and search for Blunderbore in the northland. On his journey there, he met and freed the wizard Merlin, who was trapped in a tree previously by a witch. To thank Justin, Merlin transformed Justin's old, rusty armor into a golden, comfortable, and shining armor that was invulnerable and made his sword and shield invulnerable as well. Justin's sword was so powerful it could cut through anything. Merlin also gave his horse, Victory (), giant bird-like wings that allowed him to fly (earning the new name of Winged Victory ["Buddugoliaeth Asgellog"]), and made him invulnerable.
