Gaia is a town from Final Fantasy located on the north-eastern continent of the world. Because of the mountains around it, it is accessible only by airship. There is a spring in Gaia that is home to fairies, many being found and sold to in black markets such as Caravan. Buying one and returning her to the spring will result in obtaining the Oxyale needed to breathe underwater, and thus enter the Sunken Shrine.
