For example, we are hardly told anything about the Sorceress War. But if G.F.s were involved, perhaps nobody remembers the details to tell it.

We know Sorceress Adel was a tyrant with the Lunatic Pandora as a weapon of mass destruction. Which she then used in her invasion of Trabia to the north.

But these words don't make sense. Genocide is not a conquest. And Trabia, if it was ever occupied by Esthar, must have regained its independence.

This is similar to the destruction of Lorica in FF Type 0, due to the Ultima Bomb.
