Stormpiea (ストームピア, Suto-mupia) is a massive Sky Island that constantly changes position, and can only be found through pure luck. It is inhabbited by a race of people called the Stormpieans, and is made up of something called "Storm Island Cloud", a variant of Island Cloud created when the pyroglobin ejected in the atmosphere transforms water vapor saturated with Zeuton particles, forming dark gray, electric, yet dense clouds that absorb heat and then release electricity. It is also known as the "Inventor's Dream", as there is a high-level of electric and Zeuton particle-based technology easily accessible there. It is a major setting in Grand Voyage and One Dream.
