Lyria shut her mind down and has been in a comatose state since the hostilities with the Erste Empire in Auguste. In order to awaken her, Gran and company visit the Lumacie Isles under the guidance of a mysterious woman, Rosetta. Lumacie, “the island that the world forgot,” is mainly a primeval forest full of giant, lush trees. It’s a forest that would make anyone lose their sense of direction, but Rosetta wends her way through it without hesitation. They arrive in the deepest section of forest, where an exceptionally huge tree towers over everything. When Rosetta touches the tree, Yggdrasil, the primal beast that rules over the blessings of the forest, appears before Gran and friends. With Yggdrasil’s help, Gran enters Lyria’s consciousness, made possible by the fact that they share the link of life.
