Martoka Island is best known as home of the Fillimet Magical Archives, home of all known knowledge and housed in the Mines of Martoka. The island is also home to many descendants of The Calamity at Kogal Island and their flocks of sheep.
Martoka Island is the southeastern island of the continent Ovavea. Three oceans surround the island, the Lophelian Ocean to the north, the Min Ocean to the southeast, and the Drakonan Ocean to the west. The island is spotted with wooded areas, mostly to the southwest, and contains a freshwater lake in the northeast. Beneath the island lies a large salt dome.
