Fayth

The Fayth are the disembodied souls of people, sealed in statues, whoose dreams manipulate the power of pyreflies to create many varied and powerful magical phenomena. In the world of Final Fantasy X, the Fayth are the souls of the people of Zanarkand who gave their lives to Yevon for the creation of [[Sin (Final Fantasy X)|Sin], the dream Zanarkand, and the aeons.

After Zanarkand's crushing defeat at the hands of Bevelle, Yevon, the ruler of Zanarkand, was at a loss. His summoners defeated, the army of Bevelle was now marching up the slopes of Mount Gagazet, towards the city of Zanarkand itself. In an act of desperation, Yevon took the souls of the people still living in the city, and those that had survived the battle, and turned them into Fayth for the summoning - they summoned into existance Sin, as well as the dream Zanarkand. With the power of their dreams, they summoned all of the buildings, and all of the people - everything. The Fayth are also responsible for the creation of the aeons, using their power to coalesce pyreflies into an actual physical being of great power. Even Sin itself is an extremely large and powerful Aeon.

Once a summoner of has completed his or her pilgrimage to all of the temples of Yevon, praying to the Fayth that resides at each, they meet Yunalesca in the ruins of Zanarkand. Here, Yunalesca will transform a person with a close bond to the summoner into a Fayth, a Fayth for the Final Summoning, which will destroy Yu Yevon's armor, Sin, for a short period of time, bringing the Calm to Spira.
