Link is a hero summoned by Impa, the royal nursemaid, to save Princess Zelda from the evil Prince of Darkness, Ganon, who is seeking out the shards of the Triforce of Wisdom. Link finds the pieces before Ganon does, and in the end, destroys the villain with a Silver Arrow, saving Zelda. Link's character and background are given little explanation in the game, although the prologue describes him as "burning with a sense of justice."
