of Yevon were deemed invalid after the order's secrets were exposed while the Al Bhed accepted by the Spirans with association with machina no longer sacrilegious. Spirans in general had a positive outlook with the onset of the Eternal Calm. New political groups fought for power, two being the Youth League, the New Yevon Party, while Machine Faction seeks to salvage machina. Yuna ultimately restores peace and saves Spira a second time with multiple endings based on the player's performance. Mythos In the world of Final Fantasy X and its sequel, many supernatural elements influence events in the fictional world of Spira, defining the life of the planet's inhabitants. Magic, spiritual energy, and the power of memories are heavily intertwined, and their effects manifest in a number of situations, including sporting events, religious practices, technology, and even in some of the native wildlife of the planet. The most popular pastime is Blitzball. The depiction of Sin as an "existence that agonizes the world" and as a "disaster with form" plays an important role in Spira's everyday life throughout Final Fantasy X. In Final Fantasy X-2, the population of Spira pursues additional leisures including attending concerts and a coin-collecting fad called Sphere Break. In Spira, when a person dies suddenly and unexpectedly, his or her life force, manifested as pyreflies, must be released from the body and sent to the Farplane, the final resting place of departed souls. If the sending is not performed, the body's spirit may remain trapped in the physical plane and take on the form of a fiend. A spirit of the dead may resist the transformation into a fiend, even when not sent and remain among the living, they are "unsent". The unsent play a prominent role in the storyline and mythos, including the playable character Auron and other characters including Maester Jyscal Guado, Shuyin, and Lady Yunalesca. Pyreflies Pyreflies are a mysterious, naturally occurring phenomenon that heavily influence the events of Final Fantasy X and Final Fantasy X-2, as well as the world of Spira at large. Heavily prevalent throughout Spira, these "bundles of life energy" are closely associated with death and other spiritual events and entities by the people of Spira. At high concentrations, Pyreflies are capable of recording memories, sights and sounds. Pyreflies are also associated with many commonplace technological innovations including sphere-shaped recording devices and large, suspended spherical conglomerations of congealed water
