Goddess Sword

Recently called the Skyward Sword - This sword comes to Link in the form of Phi as he's falling from his bird after Lord Ghirahim's attempted kidnapping of Zelda. After returning him to Skyloft, Link is able to use this more powerful sword on his quest to find Zelda. Lord Ghirahim cites this sword as the only reason Link still lives after their first encounter at the end of Sky Temple. Besides allowing Link to communicate with Phi, the Goddess Sword also has the power to unleash a sword beam after it's raised skyward while his hearts are full. The game will revolve around upgrading the Goddess Sword into the Master Sword.
