For 1000 years, the world of Spira was held in the grip of terror as
the great monster Sin punished it's citizens for using the forbidden
machina in the great wars. To combat Sing, powerful summoners would
make a pilgrimage to Zanarkand, the ruins of what was once the greatest
city in Spira. Able to call and control the devastating manifestations
of the fayth, aeons, into battle, these summoners would sacrifice their
lives and the life of a chosen guardian, to defeat Sin for a temporary
period of time called the "Calm." Unfortunately, the Calm
would end and Sin would eventually returne, forcing a new summoner to
forfeit their life to bring peace to Spira once again.
This cycle of life and death continued in Spira for untold generations,
until one summoner stood against the teachings of Yevon and sought a
new means by which to defeat Sin -- permanentely. The sommoner's name
was Yuna, and along with her guardians, went against the order of Yevon
and fought enemies on all sides. In a last ditch effort, Yuna and her
guardians took on Sin and defeated it forever, bringing forth a time
that would be referred to as the "Eternal Calm." Although
peace would finally last forever, Yuna was forced to say goodbye to
someone whom she cared for very much. The young man named Tidus had
been a dream of the Fayth, and when the Fayth were defeated during the
attack on Sin, their dream faded.
Yuna thought that the lover of her life had vanished alongside the
last remaining traces of Sin. But two years later, Rikku appeared in
Besaid Village and delivered a sphere found by Kimahri, Yuna's former
guardian and the new Elder of the Ronso tribe of Mt. Gagazet. This sphere
contained images of a man who resembled Tidus so closely that Yuna was
compelled to leave Besaid and begin a new search for more spheres that
might lead her closer to the truth. This game is her story.
