In a world ravaged by sins, the people's hope all lie in 'Summoners,' to save them from a abominal creature born from their own sins. A monster named Sin. Summoners embark on pilgrimages to gain and learn enough strength to cast the Final Summoning. The Final Summoning is taught to the masses as the only way to defeat the creation of Sin. The religious cult known as Yevon, has control and dominace over the masses, and because of that, all life in this world of Spira is premature. No technology or trace of any modern civilization. As the time passes, more and more Summoners attempt to destory Sin... but those attempts are fruitless. A brave Summoner will journey, with her eight Guardians, and this journey will change the soul of all who take it.
