History of the Master Sword:
According to the story of Legend of Zelda: Skyward Sword and Hyrule Historia, the Master sword was created by Hylia for the guidance of original hero to win over Demise and defeat his army. When Demise was defeated and his army sealed away, the Master sword was then used by the Hero and goddess to lift the remaining unharmed and undamaged continent along with the people of Hylia left alive, up into the high skies so that they can live in ultimate peace under the special protection of Goddess. After constant battles, the sword lost much of its powers over the time and then came to be known as the Goddess’s sword. The mighty Goddess preserved the sword in a special Holy Shrine, so that she can hand it over to the chosen hero when time comes and Demise gets resurrected. During the period of Skyward Swords, sword is washed in sacred flames and then evolved into the Master Sword for the very first time in centuries. This was the first instance the name Master Sword was used. After the chosen Links had defeated the resurrected Demise, the Master was embedded into the enchanted pedestal inside of the great Temple of time. The sword along with its pedestal was sealed inside a private chamber which was guarded by a might barrier of stone. The one worthy of title of “Hero of Time” could only pull the sword out of the pedestal and unlock its potential powers. The Master Sword laid for many years hidden in the chamber, waiting for its hero to claim it and fulfil the prophecy.
During the Events of The Legend of Zelda: Twilight Princess, it is stated by Princess Zelda that Master Sword has been crafted by the ancient Sages, who using their wisdom made a formidable weapon to battle axis of evil. This was contradictory to origin of Master Sword, but the full back story is not clear yet.
