Master Sword

The Master Sword is an ancient weapon that was first forged as a weapon to counteract evil. It has the innate power of activating the Temple of Time and is the only sword that can stop the evils of Ganon. After it was placed back in the Temple of Time by Link, the Sword disapeared only to resurface deep inside the Lost Woods a century later. The Master Sword can only be handled by the Hero of Time and his descendants.
