Emissaries of God . After the adventurer rescues seven Abyssea areas from the vile creatures that menace it , Joachim informs him that Gilgamesh wishes to meet with him again , this time in the Hall of the Gods . In the Hall of the Gods , Gilgamesh explains that he needed to use its magnetic field and introduces the adventurer to the " li ' l mistress " , Esha ' ntarl of Abyssea . Unlike Gilgamesh , she cannot traverse across worlds and has to use the magnetic energy in the hall to perform a partial dimensional crossing . Esha ' ntarl explains that the cataclysm that has befallen Abyssea is due to the will of the Twilight God , Promathia who had desired and succumbed to death ages ago . Altana , in sorrow of his death , bestowed him the light of the crystal and sundered the true crystal into five parts , creating the mortal realm . The will of Promathia to return to his full self has persisted , and the lives claimed through the cataclysm are a part of this grand scheme . His full resurrection would mean the demise of Abyssea . Although Esha ' ntarl blames herself for the events that have transpired , Gilgamesh claims it was more due to the Champions of Abyssea who have disappeared . Esha ' ntarl thus goes to investigate the matter . Later , when the adventurer rescues all nine Abyssea areas , Gilgamesh summons them to the Hall of the Gods again . Esha ' ntarl explains how numerous parallel realities have existed that are now growing unstable due to Promathia ' s will . As He gradually reverts the world to its former state of Paradise ( the realm of the Gods ) , new species of fiends have come about as a result . In Abyssea , the adventurer ' s alter - ego had once gone up against Promathia in the celestial capital of Al ' Taieu , but perhaps to no avail . Al ' Taieu , which exists in a paradox state , had been ripped out of Abyssea and should have plummeted back into Abyssea , but this has not happened . Instead , Al ' Taieu has ascended to the moon . Esha ' ntarl suggests for the adventurer to confront Promathia , but due to the cataclysmic transformation of the land , the existing portals to Al ' Taieu no longer exist . She believes the gateway is being blocked by the caturae , a species of mysterious fiends that have appeared since the cataclysm began , and urges the adventurer to seek them out and defeat them . With all six caturae in Abyssea defeated , the adventurer meets with Gilgamesh and Esha ' ntarl again , and they confirm that the caturae were linked to the Twilight God and concealing the gateway to Al ' Taieu . A spatial disturbance has manifested on Qufim Island , which could signal a path to Abyssea ' s Al ' Taieu . They entrust the adventurer with the mission to seek out this disturbance and confront Promathia once and for all . The Wyrm God . Upon traveling through the disturbance , the adventurer arrives in Abyssea - Empyreal Paradox and meets with Prishe , who is shocked to see them still alive . She explains that the adventurer ' s alter - ego had failed to stop Promathia , resulting in the events that led to the cataclysm . As she herself is immortal , she has remained trapped up in Al ' Taieu . Promathia has absorbed the darkness contained within Selh ' teus and evolved into the dreadful form of a terrifying wyrm . Considering how people from Vana ' diel gain additional powers in Abyssea , Prishe lets the adventurer confront Promathia without her aid , and they defeat its wyrmal form , Shinryu . Although Abyssea is saved from destruction , the damage He has done to the world will not revert automatically , and Abyssea will have to gradually rebuild itself back to its former glory . Prishe stays behind in Al ' Taieu to watch over Abyssea . Joachim congratulates the adventurer for having righted the world in a seemingly impossible task . Gilgamesh and Esha ' ntarl are grateful , with Gilgamesh encouraging the adventurer to pop by in Abyssea to help with rebuilding . Esha ' ntarl thanks them , but also requests that he or she pays a visit to Prishe every now and then , as the burden of all that has happened affects her the most . Prishe gets lonely in the Empyreal Paradox and has the adventurer to promise to frequent her . She and gives him or her a gift of an abyssite of the cosmos in return . Music . In addition to the two tracks also used in the previous Abyssea add - ons , " Heroes of Abyssea " introduces one new track , " Shinryu " , used in the final boss battle .
