Focus ( Fabula Nova Crystallis ) Focus is the term for the missions given to the l ' Cie by the fal ' Cie that choose them in the " " titles . Appearances . " Final Fantasy XIII " . Each l ' Cie is given a Focus , which presents itself as a vision concerning a direct or vague objective . If the l ' Cie fails to complete it before his or her brand advances to its final stage , they will turn into a monster known as a Cie ' th . According to legend , when l ' Cie fulfill their Focus , they gain eternal life ; in reality , l ' Cie who complete their Focus turn into crystal . A l ' Cie can still be revived from crystal stasis and given a new Focus . Focuses are given to the l ' Cie through visions they must interpret to know what the mission requires them to accomplish . In some cases , the missions can be straightforward and involve killing a specified creature at a given location ; in others , the l ' Cie are given little or no information , and have to discover their Focus on their own . Focuses generally lead to two outcomes : transformation into a Cie ' th , or crystallization , leading most Cocoon citizens to consider l ' Cie branding a curse . Some missions suggest certain l ' Cie are promised additional rewards for completing a Focus , such as having a loved one returned to human form from that of a crystal or Cie ' th , or being released from service as a l ' Cie ; whether these rewards were ever actually delivered to successful l ' Cie is unknown . While a l ' Cie is generally thought of as having a single specific Focus , it is possible for l ' Cie to be created without one , whereupon the l ' Cie instantly transforms into Cie ' th . Fal ' Cie were created by the gods for a specific purpose , which can be thought of as a " Focus " . L ' Cie exist as a " loophole " to this pseudo - Focus , and allow fal ' Cie to complete objectives for which they weren ' t originally created . At the Pulse Vestige , Serah transforms into crystal despite not having completed the Focus given to her . The same happens to Cid Raines later on . Barthandelus lies to the party about Serah ' s Focus , perhaps to conceal the fact Serah turned into crystal without having actually completed hers . While confronting Barthandelus in Orphan ' s Cradle , the main party , save Fang and Vanille , are briefly transformed into Cie ' th for not completing their Focus — destroying Cocoon . After reappearing , the party surmises it was an illusion conjured by Barthandelus . When Lightning declares that their Focus is to save Cocoon , the party ' s l ' Cie brands turn white , meaning they have stalled . " Final Fantasy XIII - 2 " . After Snow Villiers left Serah in search of her lost sister , Lightning , he asked a Pulse fal ' Cie ( revealed to be Cactuar in " Final Fantasy XIII - 2 Fragments After " ) to turn him into a l ' Cie . His Focus is to find Serah and fight beside her in " the fated battle " . However , he becomes trapped in the Coliseum in the Void Beyond , leaving him helpless . " " . In the aftermath of being freed from the Void Beyond , Snow is given the new Focus to protect the surviving fal ' Cie of Nova Chrysalia , Pandaemonium . Lightning ' s new task as the savior is similar to a Focus attributed to a l ' Cie . " Final Fantasy Type - 0 " . l ' Cie are given a Focus by the Crystals of Orience , and along with it , gain eternal youth . l ' Cie are not rushed into completing their Focus with the omen of being made Cie ' th , but as through their unnaturally long lifespan , they gradually forget their human memories and become detached from mortal affairs . The tasks the l ' Cie receive from their Crystal are different , but many revolve around fighting and annihilation . This leads some to speculate peace is not the Crystals ' desire , and that l ' Cie are pawns in each Crystal ' s plan to unite Orience under its respective nation . Upon completing one ' s Focus , the l ' Cie enter crystal stasis . Shards broken from sublimated l ' Cie are known as l ' Cie Stone s . Of the many l ' Cie , only a select few ever complete their Foci , let alone discern the mission they have been given . Defying the Will of their Crystal can have the l ' Cie transformed into Cie ' th as punishment . When Tempus Finis commences the Crystals send their l ' Cie to Pandæmonium to become Agito . Only l ' Cie are said to be able to enter this realm , and when Celestia helps Class Zero get there the Azure Dragon Crystal turns her into a Cie ' th as punishment . This suggests that the l ' Cie ' s final Focus is to take on the Judge ' s crucibles to be judged for their worthiness to be Agito , and Celestia helping Class Zero to become Agito defied the Azure Dragon Crystal ' s Will . Each Crystal wants the Agito to be born of their l ' Cie , as the Vermilion Bird Crystal sends its l ' Cie to fight the White Tiger l ' Cie in Pandæmonium . A " shadow " Gilgamesh Ashur is also found within Pandæmonium ; although the Gilgamesh of the current spiral never appears to travel to Pandæmonium , he may have done so previously . A Focus can also be passed on from one l ' Cie to another . The Rursan Arbiter is the judge who deems the l ' Cie ' s worthiness for Agito . He is actually a l ' Cie of the mysterious Rursus Crystal , whose true Focus may be to become Agito himself , as he or she harvests the phantoma from those who brave the Land of Judgment to take on the crucibles . Musical themes . " Focus " is the eighteenth track on the fourth disc of " " . It plays during the scene where the group ' s brands turn white before they fight Orphan in its true form . Its dominant instruments are drums . Etymology . Both " foci " and " focuses " are acceptable plural forms of the word " focus " . Although the Datalog in " Final Fantasy XIII " uses " Foci " as the plural of " Focus " , Orphan uses " Focuses " in its speech . In " Final Fantasy Record Keeper " , the word " Focuses " is used for the after - boss summary of Fifth Ark , Part 3 as the plural form .
