'By the summoning of Zodiark have we been granted a reprieve. Yet immutable as the laws he has woven may seem, they will not serve to forestall our doom.

Nay should we continue down this path, our fate will be the same. I said as much to the Convocation, of course, but the stubborn fools turned a deaf ear to my warnings. I had hoped that the defector, at least, would side with us, but I regret to report our overtures have gone unanswered.

It's funny that you should mention the survivors of the Eighth Umbral Calamity. They didn't work to undo the pain that they experienced. They worked to build a better future. What happens to them after G'raha alters the timeline is discussed in Tales from the Shadows: An Unpromised Tomorrow.

'And so our journey began anew. Would that G’raha Tia could see all that we will accomplish. Though we shall remain forever on different pages of history─and different books, besides─I take comfort in knowing we strive for a future of the selfsame brightness.'

These can only considered platitudes in that they are self-evident truths. Would that the Ancients known to heed them.
