The Garland Enigma

Garland, the main antagonist in Final Fantasy, is going to be defeated once again by the Warriors of Lights: in fact he lives a loop where the heroes defeat him each time. But NOT this time! The power of the Dark Orb and a mysterious helper make him able to win the final battle. However he then wakes up somewhere in a dungeon with no memories except of his own name... what is going on?
