The Granstream Saga - Granstream Denki USA

One hundred years ago, the planet of Granstream was ravaged by a war between the Imperial Wizardry and the Allied Spirit Army. To break the deadlock, the Imperial Wizardry unleashed a forbidden weapon long since banned by both sides, causing the planet's axis to shift and flooding the world in the process. Four wise men, aligned to the elements of fire, water, earth, and wind, managed to raise four continents into the air, saving those they could. Now however, the descendants of the wise men responsible for this noble act have begun disappearing and reports emerge that Imperial airships have been spotted. Raised by a kindly man by the name of Valos, it falls to Eon, a young orphaned boy whose wrist is adorned by a mysterious bracelet called a Scepter, to save the continents.
