One of several islands in the Northern Archipelago of Radia, Nuva Island was a small, snowy landmass that was home of the Nuva Academy, Radia's leading Xana reserach institution.

The island sunk to the bottom of the sea after the Gyth stole the Xana Crystal under study at the academy during the events of the prologue (Chapter 1).

The Gyth Seal was also located on this island, hence the initial Gyth invasion.
