Vearth (大地 (ヴァース) Vāsu?, literally meaning "Earth"; Varse in the Viz Manga, FUNimation edited dub, and 4Kids dub.) is the name given to earth by the people of Skypiea. Because Upper Yard is the only place in Skypiea where vearth can be found, it is considered a sacred substance. Before the events of Skypiea Arc, the Shandia Aisa would usually sneak into Upper Yard and fill up her bag with vearth, bringing it back home with her. During the events of the Skypiea Arc, Upper Yard was off limits to civilians. Anyone who entered was killed by Enel.
