Upon returning to the Moon Forest, Irelia managed to communicate with the sacred tree of life using her spiritual power, something no one had been able to do before. She prompted it to release a powerful burst of life energy, rejuvenating the once barren land of the Moon Forest. In a short time, numerous fruit trees and edible plants sprouted, bearing ripe fruit within a day.

After resolving the food crisis of the Moon Elves, Irelia began to establish an academy to impart magic and knowledge. The improvement in productivity alleviated concerns about food, leading to a rapid population growth and a substantial enhancement in overall strength.

The racial talent of the Elves meant that many were born with a natural aptitude for magic. Although there were differences in aptitude, generally three to four out of every ten could become mages. Those who couldn't become mages could still become excellent archers thanks to their eagle-eye talent.

Irelia then combined the roles of mages and archers to create a new profession: the Magic Archer. Magic Archers possessed both the physical attack capabilities of warriors and the magical attack abilities of mages, becoming the most powerful profession on the Alvin Continent. Consequently, the Moon Elves became the strongest among the four Elf branches.
