Revision 1

Olderion is the capital of the Olderion Federation in Final Fantasy Resonance, introduced by Square Enix on July 16, 2026. It is styled the Aquapolis, and it is blessed with abundant, crystalline waters.

The Wardens of the Waters

Olderion has long been safeguarded by a clan known as the Wardens of the Waters, who are also the longtime guardians of the Water Shrine. The city is kept safe by the prayers of the Maiden of Water, one of the Wardens, and by an esper known to locals as the God of Water. Nichol, the Federation's strategist, was brought up in a Warden family.

Before the Airships

Before the proliferation of airships, Olderion was a juggernaut in the shipbuilding industry and a thriving naval transport hub. That history sits directly opposite Dilmagia's, which grew on the technology that displaced it, and it lines up with the game's confirmed traversal, where ships carry travellers between continents before an airship becomes available.

Elsewhere in the World

Olderion is one of a small set of places Square Enix has named. The Zoldaad Empire, a military nation that holds the Fire Crystal, and Mysidia, the fabled city of mages said to host the Ice Crystal, were both revealed in August 2026. Locations carries the full list.
