Now as Shigaru Miyamoto metioned in one of his interviews, Link is from a city in the skies, and the world is already in chaos. judgeing from the minor descrption and details we've heard so far we've come to the conclusion that skyward sword's story may date back to pre-triforce times. In Zelda Ocarina of time we get the back story of how the world was in chaos and peril until the three godesses of light came and gave order to the world, and then used the last of their being to form the triforce. Now after the godesses form the triforce, the kingdom of Hyrule was born. Miyamoto said in the the Nintendo press conference that they'd be taking a diffrent approach with this Zelda game, and that it wouldnt take place in hyrule. No triforce = No Hyrule, hence I come to the conclusion that this takes place at the beginning of the timeline, before the creation of the triforce. Now in the regular Zelda games Link is a Hylain, but Miyamoto stated that Link is from the city in the skies, so that further backs up my theroy, because there is no longer the tie between Link and hyrule.
