Eventually Marche succeeds in his quest to return Ivalice to normal. He achieves this by destroying the crystals, or world threads, of Ivalice, defeating Llednar Twem (the manifestation of Mewt's negative emotions), and killing the Li-Grim, the physical manifestation of the book's wish-based magic that had been masquerading as Mewt's mother, Queen Remedi. He teaches the other children in the process that they cannot live in fantasy but must learn to live with their misfortunes in reality. The other children are wiser from the experience, as the ending reveals them all to have become happy with themselves.
