Tilia, who is the Third Tower itself, is nearing the end of her lifespan, and her death will result in the Tower’s disappearance. This causes chaos for the people of Sol Cluster. Aoto and others begin a plan to extend Tilia’s life, though it will cause her great suffering. The story is original and follows events after the PlayStation 3 RPG. Characters from the first two games appear and assist in dealing with the Third Tower’s impending end. The outcome of Tilia’s fate remains uncertain.
