Aeon

The word aeon /ˈiːɒn/, also spelled eon and æon (in American English), originally meant "life", "vital force" or "being", "generation" or "a period of time", though it tended to be translated as "age" in the sense of "ages", "forever", "timeless" or "for eternity". It is a Latin transliteration from the koine Greek word ὁ αἰών (ho aion), from the archaic αἰϝών (aiwon). In Homer it typically refers to life or lifespan. Its latest meaning is more or less similar to the Sanskrit word kalpa and Hebrew word olam. A cognate Latin word aevum or aeuum (cf. αἰϝών) for "age" is present in words such as longevity and mediaeval.

Although the term aeon may be used in reference to a period of a billion years (especially in geology, cosmology or astronomy), its more common usage is for any long, indefinite, period. Aeon can also refer to the four aeons on the Geologic Time Scale that make up the Earth's history, the Hadean, Archean, Proterozoic, and the current aeon Phanerozoic.

Characters of Final Fantasy X and X-2

The tenth game of the Final Fantasy series, Square's 2001 bestselling role-playing video game Final Fantasy X features several fictional characters designed by Tetsuya Nomura who wanted the main characters' designs and names to be connected with their personalities and roles in the plot. The game takes place in the fictional universe of Spira that features multiple tribes. The game's sequel released in 2003, Final Fantasy X-2, takes place two years after the events in Final Fantasy X and uses new and returning characters.

There are seven main playable characters in Final Fantasy X starting with Tidus, a skilled blitzball player from Zanarkand who is lost in the world of Spira after an encounter with an enormous creature called Sin and searches for a way home. He joins the summoner Yuna who travels towards the Zanarkand's ruins in order defeat Sin alongside her guardians: Kimahri Ronso, a member of the Ronso tribe; Wakka, the captain of the blitzball team in Besaid; Lulu, a stoic black mage; Auron, a famous warrior and an old acquaintance of Tidus; and Rikku, Yuna's cousin who searches for a way to avoid Yuna's sacrifice in the fight against Sin. The leader of the Guado tribe, Seymour Guado, briefly joins the party for a fight but is then revealed as an antagonist in his quest to replace Tidus' father, Jecht, to become the new Sin. Final Fantasy X-2 features Yuna, Rikku, and the newly introduced Paine as playable characters in their quest to find spheres across Spira and find clues regarding Tidus' current location. During their journey, they meet Paine's former comrades who are related with the spirit of an avenger named Shuyin.
