Skyloft

Skyloft (pronounced, or  ) is a series of large islands floating above the clouds in SS undefined. The main island includes the Bazaar, a large residential quarter, a bathhouse, as well as a plaza and the Light Tower. Other places among the other islands are the Knight Academy, a boarding school run by Gaepora that Link and Zelda attend along with several other students, and the Isle of the Goddess, which holds the Statue of the Goddess.

Features
Skyloft is a set of floating islands in The Sky and is inhabited by humans who descended from those who lived among the Goddess Hylia. The citizens of Skyloft are noted for tranversing the sky by riding large birds of varied colours. The floating civilization is home to a number of notable features including the Bazaar, the Knight Academy, the Waterfall Cave, the Statue of the Goddess, Beedle's Air Shop, a Graveyard and a large number of households. During the day, Skyloft is full of life, but becomes infested by Keese, Chuchus, and Remlits during the night as result of Batreaux's curse.

History
Skyloft was created at the end of the Era of the Goddess Hylia when a crack in the earth appeared, and from the fissure came Demise and his demonic hoards. They launched a massive assault on the world known as the Surface, burning forests to ashes, choking the land's sweet springs and killing without hesitation. Hylia gathered the surviving Hylians on a small outcropping of land and sent them along with the Triforce skyward to protect them and the sacred relic from the demonic hordes that had overrun the surface world. This plot of land became known as the Isle of the Goddess and along with other floating islands constituted the new home of the Hylians, which became known as Skyloft.

In order to keep the sacred power from falling into the hands of Demise, Hylia also hid the portals to the three pieces of the Triforce within Sky Keep, and enshrined the Goddess Sword inside the Statue of the Goddess, to be found by a chosen hero when the time was right. Skyloft remained in the sky above the clouds for generations, knowledge of the Surface and the origins of Skyloft becoming nothing more then a mere legend. Despite knowledge of their origins dwindling, however, the present people of Skyloft still knew of the Goddess Hylia and believed she watched over them to that day, unaware that she was living among them in a mortal form in what was now known as the Sky Era.

25 years prior to the events of Skyward Sword, the people of Skyloft established the Knight Academy, a school for the Knights of Skyloft, and the Wing Ceremony, an annual yearly event where students at the Knight Academy would engage in the ceremony to advance to their next level in class. It concludes with the winner reenacting the role of the Goddess's Hero from long ago with another student playing the role of the Goddess herself. In the present events of the story, Link goes up against Cawlin, Strich and Groose in the ceremony, winning and getting to spend personal time with Zelda, playing the role of the Goddess and giving him the Sailcloth she made. As she is about to tell Link something personal that has been on her mind, she is swept away to the surface world by a tornado conjured by Ghirahim. Link wakes up, seeing a figure, later known as Fi, and begins to follow the figure into the interior of the Statue of the Goddess. Upon entrance, the figure reveals itself to be Fi, and instructs Link to pull out the sacred Goddess Sword and raise it skyward. After Link raises the sword, Gaepora walks in, and Fi gives Link the Emerald Tablet, and instructs him to place the tablet into the alter. As an effect of the tablet, a rift in the clouds forms, revealing a path to The Surface, where Fi says Zelda is located. Late in the game after learning the Song of the Hero from Levias, Link discovers the Sky Keep, an ancient temple that was built inside the Isle of the Goddess with the sole purpose of protecting the Triforce. After venturing inside and reciving the Triforce, he wishes for the eradication of Demise, and upon being granted the Isle of the Goddess breaks off from the remainder of Skyloft and begins to desecent towards The Surface. The isle settles in the large spiral pit in the Sealed Grounds, successfully destroying Demise.

After Demise is successfully killed in the past, various people of the present day Skyloft including Gaepora, Cawlin, and Strich journey to the surface and seemingly discover their true origins. It would seem that, over time, people from Skyloft, like Link and Zelda, chose to stay on the surface world as, and by the time of the Force Era, many humans live on the surface world that has come to be known as Kingdom of Hyrule.

Hyrule Warriors
Skyloft appears as the Land in the Sky stage in. Some islands from the Sky appear crashed upon Skyloft, including the Pumpkin Landing. Levias also appears as part of the stage.

Super Smash Bros. for Wii U
Skyloft appears as a stage in Super Smash Bros. for Wii U. It features a moving platform which lands in different areas, including the Statue of the Goddess, the Bazaar, the Light Tower, and the outside of Batreaux's house.

Theory
The Loftwings which inhabit Skyloft are depicted as directly serving the goddess Hylia, and the protagonists' Loftwings are instrumental in bringing the Hylians back to the Surface so that they can found Hyrule. As such, they perform the role attributed to the Oocca's ancestors in, making it likely that the City in the Sky the Oocca inhabit is the ruins of Skyloft after the departure of the Hylians.
