Datalog / History and Myth The following is a list of Datalog entries for the History and Myth of " Final Fantasy XIII " . Pulse . Resting in Cocoon ' s shadow , the sprawling and enigmatic lowerworld of Pulse is home to a multitude of terrors . The land is commonly believed to be inhospitable to human life , and a strict ban on interworld travel forbids citizens of Cocoon from venturing there to challenge this hypothesis . Not even members of the Sanctum ' s upper echelon can claim to have seen the surface with their own eyes , but the attempted invasion by the world ' s savage armies several centuries ago is well documented . Widespread fear of a repeated assault persists among the populace even today , with colloquial references often likening the world to a manner of living hell . Pulse fal ' Cie . Fal ' Cie are an existence beyond human comprehension , possessed of incredible magic power . The ones responsible for Cocoon ' s construction are protectors of humanity , but there are others of their kind as well : the fal ' Cie who dwell on Pulse and name themselves enemies of Cocoon . Humans who encounter Pulse fal ' Cie are cursed , being turned to l ' Cie and ordered to destroy Cocoon . It is for this reason that most ordinary citizens support the Purge - anyone who may have come into contact with one of these fal ' Cie represents a dire threat . Pulse l ' Cie . The beings known as fal ' Cie possess the power to enthrall unwilling human instruments , compelling the victims to serve their will . These individuals , known as l ' Cie , are marked with indelible brands . They gain the gift of magic , but also bear the burden of completing a task known as a Focus for their fal ' Cie master . Pulse l ' Cie - tools of fal ' Cie from the world below - are considered dangerous enemies of Cocoon ' s society . As there exists no means of removing the l ' Cie brand and the curse thereby imposed , Pulse l ' Cie are hunted relentlessly . Cie ' th . When a fal ' Cie takes a human to be one of its l ' Cie servants , that person is given a Focus to be completed . Should the l ' Cie fail to fulfill this Focus before his or her brand advances to its final stage , that l ' Cie becomes a Cie ' th . Mired in eternal sorrow and regret , and robbed of all free will , Cie ' th are damned to wander the world , unliving and undying , until their corrupted flesh at last can move no more . For Cie ' th , there is no salvation . Brands . The brands that mark a l ' Cie as one of the fal ' Cie ' s chosen change gradually , passing through several different stages . When the " eye " at the center opens - the brand ' s final stage - the l ' Cie become a Cie ' th . A brand ' s rate of progression depends partly on the difficulty of the l ' Cie ' s Focus . It is also linked closely to the individual ' s mental state , with severe psychological trauma sometimes spurring rapid advancement . In the most extreme cases , severe fear and shock at being made a l ' Cie has turned newly made l ' Cie into Cie ' th at the instant of their branding . Crystal stasis . For l ' Cie , successful completion of a Focus holds the promise of eternal life in the peaceful slumber of crystal stasis - or so the legends say . Yet to spend an eternity as an immobile crystal is not so very different from death . The people of Cocoon consequently fear being marked as a l ' Cie , equating the fal ' Cie ' s brand with a death sentence . Faced with only the choice between eternal damnation as a Cie ' th and eternal imprisonment in crystal , it comes as little surprise that many l ' Cie decry their fate . Eidolons . These mystical entities reveal themselves before only a select few l ' Cie . It is said that they are saviors , come to rescue helpless l ' Cie who find themselves bound to a Focus against their will . If this is true , they offer a salvation few indeed would seek willingly : without exception , Eidolons attack the l ' Cie whose presence they grace . There have been no l ' Cie in Cocoon for centuries , and as a result , no way of determining the truth behind tales of these beings . To the citizens of Cocoon , they remain the stuff of bedtime stories . Ragnarok . Lightning , Snow , and the others saw a phantom vision of this beast upon their branding as l ' Cie . In the dream , they witnessed the creature besieging Cocoon ' s capital of Eden , but whether this was a glimpse of past events or a vision of things to come was unclear . What is clear is that Ragnarok is inextricably linked to their Focus . The nature of that Focus , and what must be done to fulfill it , remains to be seen . The War of Transgression . Several hundred years ago , the armies of Pulse attempted to invade Cocoon in a conflict known today as the War of Transgression . The Sanctum ' s fal ' Cie were able to repel the lowerworld forces before they breached Cocoon ' s interior , but not before they managed to seriously damage areas lying near the world ' s outer rim . Details surrounding the clash remain shrouded in mystery , but the government ' s swift and decisive response to this violent Pulsian transgression minimized casualties and greatly boosted public faith in both the Sanctum and their fal ' Cie . Lowerworld Artifacts . In the aftermath of the War of Transgression , regions near Cocoon ' s outer rim were left uninhabitable due to the severe trauma they had sustained . To undo this damage , the fal ' Cie gathered materials from the surface of Pulse and rebuilt Cocoon ' s wounded landscape using them . Bodhum was one city so affected , and like the others , it still bears lingering traces of post - war reconstruction in the form of leftover lowerworld artifacts . The Pulse Vestige that hid a dormant fal ' Cie was one such artifact . Cie ' th Stone s . L ' Cie who fail their Foci become Cie ' th , cursed to wander the wilds in a form of living death . Only after many years and much suffering do they extinguish the last of their strength and cease to roam . When this happens , the Cie ' th ' s remains slowly fossilize , turning into what is known as a Cie ' th Stone . However , this transformation does not mark an end to the Cie ' th ' s regret and sorrow at having failed . Even after having turned to stone the Cie ' th cry out , imploring other l ' Cie to fulfill the Focus they could not . The Undying . The Undying are fearsome Cie ' th who , cursing their former fal ' Cie masters for forsaking them at the end of their forced servitude , refuse to surrender their connection to this world . Whereas normal Cie ' th eventually cease their wanderings and turn to stone , the Undying rage on , fueled by a jealous hatred of all living things . Retaining the defiant strength of will they knew in life , they act on instinct , doling out death and destruction to all that dare cross their path .
