The island of Vylbrand is part of the region of Eorzea. It lies off the western coast of Aldenard and is home to the city-state of Limsa Lominsa, which is located on the island's southwestern coast. Vylbrand is bordered by the Rhotano Sea to the south, the Indigo Deep to the northwest, and the Strait of Merlthor to the east. Several smaller islands are connected to the main island by brilliant ivory bridges.
Regions located on the island include La Noscea on the southern side and O'Ghomoro in the north. The island is divided in half by a large volcano at its center.
