The Warrior of Light rejoined

So a story where the ascians win?

So a story where the ascians win?

A story where the Ancients never turn into Ascians. No Zodiark -> no servants of the Dark Lord.

But this will never happen, because (quoting Elidibus' words from Hope upon a Flower):

Yet even should you manage to interact with others, you will be unable to effect meaningful change.
For the reality you wish to save—the reality to which you must return—exists as a result of the Final Days.
You cannot reshape the past to undo the tragedies of the present. Cannot unmake the sorrow and suffering fated to come.

Or with other words: Time travel never works as expected. Or unexpected. In the end, it never works.

Except for Graha Tia, who did exactly this (travel into the past to undo the tragedies of the present).
