The Epic Journey of the Black Mages to the Outer Continent!

The story of the relationship between Quale and Vivi's grandfather.

The tale of events that placed Ipsen's Castle in the state it is today.

Maybe a story devoted to Tantalus' perspective of events occurring throughout the story. (the game did a nice job doing that though I must say!). Maybe Blank was aware of his petrified state the entire time or something.
