[Summary] Ecology of Three Terrestrial Creatures

On Planet Asteria, there exists 'Feri,' innocent animals that, as base lifeforms, live purely without language, reveling in life. If Feri receive the blessing of Gems, they evolve into 'Zena,' and if they harbor a Star's Fragment (Stella), they become 'Starvi.' Zena and Starvi have entirely different origins and do not transform into each other through mutation. Zena, being an evolutionary lineage that gained intelligence through the blessing of Gems, has built a civilization close to humanity, walking on two legs and wearing clothes. They have a concept of growth, and becoming an adult requires growth as a pure lifeform and the blossoming of intelligence (control of Gems). They are also long-lived but have a lifespan. Conversely, Starvi are mystical beings imbued with the pure power of Star's Fragments, appearing close to animals without wearing clothes. Since the form of life is fixed when Feri harbors a Star's Fragment, they are in their complete form from the moment of birth and do not undergo a process of growth. Therefore, they also do not have the concept of a lifespan. Both Zena and Starvi seem to retain faint memories of their time as Feri. Orl, the Great Elder Senia, appears to retain memories of the dark ages before the Gemstones fell (A.G. Year Zero).
