She's the goddess worshiped by all creatures of Elf Lakeside, and the leader of the High Elves. She led her followers in Elf Lakeside to defend against the invasion of the ancient Demongod Gordia and eventually, with the help of Sword Maiden of Shooting Stars, eliminated the Demongod and saved the world.
