Sky Island

The term Sky Island (空島, Sorajima) can refer to any island located in the sky. Known Sky Islands include:


 * Skypiea (consists of Angel Island and Upper Yard)
 * Bilka
 * Weatheria

Urouge's homeland is also a Sky Island, however, its name was not stated.

The existence of Sky Islands is largely mocked or ignored by many, to those living in the Blue Seas the idea of an island in the sky seems illogical or impossible. Getting to a sky island is difficult due to its location, although not entirely impossible.
