 The fayth ( <unk> , <unk> , lit . " prayer child " ) are humans who willingly give up their lives to have their souls sealed in statues and commune with summoners with whom they have established a mental link . This link grants a summoner access to a fayth 's dreams and enables him or her to physically realize those dreams as aeons ( <unk> , <unk> , lit . " summon beast " ) , powerful creatures which may be employed to aid the summoner in battle or in a time of special need . During the events of Final Fantasy X , the fayth of the aeon Bahamut serves as the chosen representative of the fayth as a collective . The fayth aids High Summoner Yuna and her guardians in bringing the spiral of death to an end , which results in their own passing . In Final Fantasy X @-@ 2 , the fayth return in their aeon forms , this time having been overcome by the despair and malice of Shuyin , rendering them his unwilling puppets of chaos . Yuna and her allies free both the fayth and Shuyin from the darkness that has consumed them . Ten aeons are identified in Final Fantasy X : <unk> , Ifrit , Shiva , Ixion , Bahamut , Anima , Yojimbo and the three Magus Sisters . The game builds on mythological figures through the inclusion of the aeons , such as the Arabic Ifrit , the Hindu deity Shiva and even the Jungian figure Anima and the demon <unk> . Wilder wrote on the Jungian analysis of Anima and tied Square Enix 's depiction of the Aeon as both a representation of Seymour 's corruption . Wilder analyzes the chained and blinded depiction of the figure that is Seymour 's mother and tying the form to her bound to servitude to Seymour in his descent into madness .
