Having lost much of her power in the previous cycle, Cosmos gives her ten warriors—Warrior of Light, Firion, Onion Knight, Cecil, Bartz, Terra, Cloud, Squall, Zidane, and Tidus—the task of retrieving the ten crystals that will help them defeat Chaos.[9] They each set out on a journey called a "Destiny Odyssey", where their respective stories are told and interlink with one another.[10] During their travels the heroes encounter their villains, defeating them through epiphanies about themselves that help them obtain their crystals.
