Link is from a floating island in the clouds called Sky Loft. Link doesn't think his world is unusual -- it's just where he lives. Then he discovers another land beneath the clouds. The other world is dangerous and ruled by evil. Link is forced to go into that world due to circumstances. He has to travel back and forth between lands. The Skyward Sword is the key. The sword transforms, talks to him, gives him advice, etc. Skyward Sword becomes the Master Sword.

In my preview of Skyward Sword, several of you left comments about the game's art style, feeling that it was a step back from Twilight Princess. Miyamoto explained that the art was influenced by impressionism and cited Paul Cezanne's work in particular.
