While we don't know much about the upcoming Zelda entry, Skyward Sword, we do know of the existence of Skyloft, a land above the clouds that is separated from the surface world we're familiar with. It's not the first time a land separated from the normal world has appeared- the mythical Sacred Realm, a land supposedly situated high in the heavens, has also appeared. Could Skyloft be that Sacred Realm?

"...there's no denying that the idea bears at least a passing reminder of the similar distance between Hyrule and the Sacred Realm. The fact that the surface world is plagued by evil while Skyloft (as far as we know) still remains pure may further demonstrate the similarities, as the seals on the Sacred Realm exist to protect it from the evils that might try to dominate it."
