the Master Sword

In the video game series "The Legend of Zelda", the Master Sword is the sword you need to get in order to defeat Ganon, the porcinous King of Evil. The Master Sword may only be pulled from its pedestal by a righteous and courageous person. Link, an orphan boy who gets involved in the plot by happenstance/coincidence turns out to be this chosen person, and after proving himself to the gods, he is allowed the Master Sword and uses it to challenge Ganon. The Master Sword is not only a sword though. In the storyline for "Ocarina of Time" it acted as a key, and its pedestal was the lock. Upon removing or inserting the sword from the pedestal, you could travel back and forward in time by about seven years. In the storyline for "A Link to the Past", the Master Sword shoots a magical energy beam out of the end when Link is full on life energy. In all storylines involving the Master Sword, major enemies (including Ganon) attempt to fire evil magic beams at Link intending to kill him. This is where the Master Sword comes in handy; it is immune to evil, and can be used to deflect the evil away from Link, most of the time back at its caster. The Master Sword is commonly referred to as "The blade of evil's bane". Tragically, upon pulling the Master Sword from the pedestal, the ancient seal on Ganon's magic is broken, and he only becomes stronger. Such is the fate of Link, Ganon, and Princess Zelda.
