Fibernia (フィベルニア島 Fiberunia Shima) is the largest of the three largest islands in the Western Isles featured in Fire Emblem: The Binding Blade and is located in the middle of the archipelago. Important locations on the island are Jutes, the capital of the Western Isles, Mt. Eburacum, the Mines of Death where slave labor is used to mine for natural resources, and Castle Armagh, a fortress guarding a valley leading to Mt. Eburacum.
Fibernia is a loose reference to Hibernia, the Classic Latin name for Ireland.
