blastia thief. On their journey, they also meet Karol, a trainee hunter separated from his guild; a blastia researcher named Rita; Raven, a Great War veteran; Judith, a Krytia who seeks to destroy the blastia harming the aer balance; and exclusive to the PS3 version only, seemingly the descendant of a legendary pirate Aifread named Patty Fleur. Together, the group recover the stolen core from a corrupt guild leader and return it to Yuri's friend and former fellow knight Flynn. Yuri and Karol then decide to form an independent guild called Brave Vesperia. Shortly after this, Estelle is attacked by an Entelexeia called Phaeroh, who accuses her of poisoning the planet. After investigating and meeting a second time with Phaeroh, Brave Vesperia learn that Estelle is a Child of the Full Moon, capable of converting aer into magic without the aid of a blastia core, and that her actions are causing the aer krene, the sources of aer, to overproduce aer with deadly results. Alongside these events, Yuri sees that the Imperial authorities are powerless to act against powerful figures involved in blastia abuse: he takes matters into his own hands and murders two officials connected to the abuses. These acts put a strain on his friendship with Flynn. After this, Estelle is kidnapped by Raven, revealed to be an agent of Commandant Alexei, leader of the Knights and the mastermind behind the blastia thefts: Alexei intends to use Estelle's power and the replica of a magical sword to activate an ancient weapon called the Enduring Shrine of Zaude and remake the world, erasing the harmful blastia. After Raven decides to remain with Brave Vesperia after helping Estelle to escape with them, the group travel to Zaude to stop Alexei. They fail, and as Zaude is activated, it is revealed to be a barrier generator which kept the Adephagos sealed off from the world. As the Adephagos is released, Alexei is killed as Zaude collapses and Yuri is separated from the group after one of Flynn's subordinates attempts to kill him without Flynn's knowledge. Rescued by Duke, Yuri decides to stop the Adephagos. During his absence, Rita discovers a means of converting blastia cores into spirits, which can process aer into a less-dangerous alternate energy called mana, stabilizing the aer krene and keeping Estelle's powers in check. In turn, the mana could power a weapon capable of destroying the Adephagos.
