Vearth

Vearth is the name that the people of Skypeia call the dirt found on Upper Yard. Because Upper Yard is the only place in Skypeia where Vearth can be found, it is a sacred substance. Before the Skypeia Arc, the Shandian Aisa would usually sneak into Upper Yard and fill up her bag with Vearth, bringing it back home with her.
