Taking place two years after Yuna's fateful journey to defeat Sin, the once chaotic world of Spira has gone through a massive transformation, entering a period of "Eternal Calm". The people of Spira now shun the teachings of Yevon and have opened their arms to former foes, the Al Bhed and the use of machina. The Machine Faction aims to propagate the use of machina in Spira, going as far as renaming "machina" to "machines" to remove the stigma. However, even with the peaceful life they now lived, there is emptiness in Yuna's heart that is keeping her from moving on as the others have.
