Skypiea

Skypiea (スカイピア, Sukaipia?) is a land located in the sky above the Grand Line. So far, three island have been confirmed in Skypiea, which are "Angel Island", "Shandora", "Bilka" (which has been destroyed by Eneru), and "Weatheria". The people are unique in that they have small wings on their backs. The daily life of sky people revolves around the use of "Dials", which normally aren't available in the Blue Sea. As opposed to the "Berry" of the rest of the world, it uses "Extol" as currency.
