Dragon Quest Vii

The story begins when the father of the protagonist brings home a map fragment from a fishing trip; this map suggests to the protagonist and his friend that the world had, at some point in its past, many continents, though now there is only the small island of Estard (エスタード, Esutādo). The two of them find a way to travel back to the past, when the continents still existed. The continents are facing serious problems that threaten their existence; the protagonist and his growing party work to resolve the problems, and when they do, the continents reappear in the present. When all the continents are finally restored, the party confronts the Demon Lord Orgodemir, who long ago defeated God (The Almighty in the 3DS English translation) and is responsible for the continents' disappearance. After his initial defeat, Orgodemir returns in the present and poses as God to trick humanity into worshiping him, then seals the continents away again. The party summons the Four Elemental Spirits to expose Orgodemir, then travels to the Dark Palace where they defeat Orgodemir in a final showdown.
