Spira

The fictional events of the Square Enix role-playing video games Final Fantasy X and Final Fantasy X-2 take place in a world called "Spira" (スピラ, Supira?). As befitting its name, Spira is characterized by cycles and repetition, such as the spiral of death that the world endures, the many spheres found in Spira, the blitzball sphere pools, the prayer to Yevon, the Sphere Grid, and Spira's cycle of life energy emerging from within the planet's core, granting life to all its living inhabitants, and then returning to the core when a life form dies.1

As an invention of Square Enix, Spira is one of the first Final Fantasy worlds to feature consistent, all-encompassing spiritual and mythological influences within the planet's civilizations and their inhabitants' daily lives. The world of Spira itself is very different from the mainly European-style worlds found in previous Final Fantasy games, being much more closely modeled on southeast Asia, most notably with respect to its vegetation, topography and architecture.
