Dying World A Dying World is a location in " Final Fantasy XIII - 2 " . Set in the year 700 AF , the Dying World was once home to the Farseers , including seeress Paddra Nsu - Yeul , her Guardian Caius Ballad and his apprentice Noel Kreiss . It is an ash - covered wasteland in perpetual overcast , and has but an abandoned village . Some players have reported Mog getting stuck hovering or spinning in place in Dying World . Since Mog cannot be thrown in the area , and the Historia Crux only allows the player to visit Serendipity and the Coliseum at the time , he remains unable to uncover necessary people and elements in the area , and the player cannot move forward in the story . There is no known way to fix this issue aside from loading an older save before Mog rejoins Serah . It is recommended to create a new save on the timeline screen before entering A Dying World . " One of the prophecies recorded on the Oracle Drive excavated from the ruins shows a mysterious place called the Dying World . It appears to be inhabited by descendants of the ancient Paddra Farseers , as well as refugees from Cocoon . Scientists believe that this world is our distant future . " " Frankly , we ' re not sure if anyone would actually want to visit the place . But " We ' ll take you to the ends of the earth ! " is our motto , so we ' ve sent our crack intern researcher to check it out . We ' ll let you know the moment we hear from him again . " Story . Noel was born to the Farseer tribe in a post - apocalyptic Gran Pulse that is slowly dying away due to the disaster that was brought on by Cocoon ' s crystal pillar crumbling two hundred years ago . Cities have been wiped out leaving people to survive in nomadic ways . As most of the world ' s flora and fauna have gone extinct , the people see they are at the end of the world . Noel was cared for by his grandmother , and when Yeul was born to the village , Caius arrived to be her Guardian . Yeul ' s previous incarnation had wished for her final self to be able to live a normal life , and thus Caius did not isolate her from other people like he had done with Yeuls of the past . Noel was always protective of Yeul . He sought to become a Guardian to her , and Caius made him his apprentice . The villagers died one by one from hunger and illness until only Noel , Yeul and Caius were left . Whether it was an old custom or a new preoccupation with preserving the Farseers ' future , members of Noel ' s tribe told him before passing , " The future is yours " . Serah travels to the Dying World to save Noel from becoming trapped in the dream Caius placed him in that recreates his final days in the Dying World . Her moogle companion Mog follows her as a shadow , but his soul is trapped in the Void Beyond and Serah cannot talk to him . She witnesses the events from Noel ' s past : his lonesome hunt for a behemoth for Yeul ' s 15th birthday party , and a conversation between Noel and Caius that reveals that to become the next Guardian one must kill the predecessor . Noel refuses to succeed him that way , and tells of his plan to take Yeul on a journey to find other people so she would not be lonely . Caius claims this is a futile dream and forces Noel into a battle and overpowers him . Seeing that Noel is not strong enough to kill him , Caius abandons his post as Yeul ' s Guardian for the first time in centuries and leaves for Valhalla , his plan to slay the Goddess Etro to destroy the timeline and save Yeul from her cycle of reincarnation . Noel , who had previously been unaware that Yeul ' s seeress powers would soon kill her , finds her at the Farseers ' Relic by an Oracle Drive . She has a vision of the future and passes away , leaving Noel alone . He decides to follow Caius to Valhalla and prays for the goddess to grant him the power of chaos . As Noel ' s prayer is answered and he is being pulled away toward a light in the sky , Serah ' s voice reaches him and he realizes he was living in a dream world . His phantom memories disappear and the sky clears out , leaving only the barren land . Some of Noel ' s lost memories are restored and he remembers how Yeul died . At the Farseers ' Relic , the Oracle Drive reveals that Yeul had seen Noel ' s journey through time , and the final vision she had implanted into the Drive shows a hazy vision of her reuniting with Noel on a grassy field , invigorating Noel ' s hope of one day seeing her again . Mog ' s soul is returned to his body and he informs Serah and Noel what he learned from Lightning in the Void Beyond : Caius was once a Pulse l ' Cie charged with a Focus to protect Yeul , but was freed from his fate by Etro and granted immortality to watch over the seeresses throughout time . Despite now knowing that her Eyes of Etro eat away at her life until a vision will kill her , Serah continues on her chosen path to change history . Noel , Serah and Mog find a Time Gate and leave the Dying World on their quest to find a way to Valhalla , the world that exists between the mortal world and the unseen realm .
