Until the Stormblood expansion, only the map for the Eorzean realm (comprised of the main continent of Aldenard and the island of Vylbrand off Aldenard's western coast) had been revealed in terms of Hydaelyn's geography. An expanded map with the second expansion revealed the layout of the Three Great Continents, though much of Ilsabard remains terra incognita while distant realms such as Meracydia are largely unknown.
