Location from One Piece by Eiichiro Oda
A sky island 10,000 meters above the sea, built on clouds made solid by Pyrobloin particles. Ruled by the tyrannical 'God' Enel until the Straw Hats liberated it. The golden city of Shandora lies hidden within.
Skypiea challenges everything the Blue Sea dwellers believe about the world. An entire civilization exists on clouds that shouldn't be solid, using technology (Dials) that the surface world has never seen. The native Skypieans and the Shandians — descendants of the surface city Shandora, blasted skyward by a Knock Up Stream — fought a 400-year war over the land, manipulated by successive 'Gods' who claimed divine authority. Enel was the worst: a Logia user who believed his Goro Goro no Mi (lightning) literally made him God. He planned to destroy Skypiea entirely and sail to the moon on his ark Maxim. Luffy, immune to lightning thanks to his rubber body, was the one person in the sky who could hit him. The golden bell of Shandora, rung by Luffy at the arc's climax, was heard on the surface by Montblanc Cricket — proving that the city of gold his ancestor was executed for claiming to find really existed.
Islands of cloud — some solid enough to walk on (Island Clouds), others forming rivers and seas in the sky (Sea Clouds). The Skypiean villages are built on cloud platforms with shell-based technology: Dials that store wind, heat, light, and sound. Enormous beanstalks connect upper and lower cloud layers. The ruins of Shandora — a city of gold from the surface world, blasted into the sky by the Knock Up Stream 400 years ago — sit half-buried in cloud and vine. Enel's floating ark Maxim looms above everything. The sky stretches endlessly in all directions; there is no horizon, only more sky.
