The , also known as "The Blade of Evil's Bane", the "Sword of Resurrection", or the "sword that seals the darkness" is a divine, magic sword that often acts as the ultimate weapon for the various Links in their quest to save Hyrule. It is one of the few weapons capable of harming Ganon and a key to the Sacred Realm. First introduced in "A Link To The Past", it has the power to "repel evil", which enables it to overcome powerful dark magic and slay evil and demonic beings that otherwise cannot be harmed by conventional weaponry. In "", the blade is revealed to have originally began as the Goddess Sword, which had a sentient female avatar named Fi integrated into it. Near the end of the game, the Goddess Sword transforms into its current state after being infused with the Three Sacred Flames, with Fi's spirit form ceasing to be once the Master Sword absorbs the Demon King Demise's remains.
