If you did the quest line for ARM/GSM/BSM, you repair the Golden Dhyata (A mammet specializing in the translation of languages), which in the wake of the quest repeats these words stated to have been taken from a book detailing the manipulation of the Lifestream using magicks.

"The serpent that sleeps in the deep slowly sheds its skin of old.

Eventually, the serpent devours its own tail, and renders new flesh using its own. The pain felt with cause the earth to quake, the mountains to crumble, and the rivers to run dry. Thus, seven wedges must be driven into its back."


It's also mentioned that there were anomalies in the Lifestream that were under investigation in the same questline.

I can't help but wonder if perhaps Zodiark's destruction and the subsequent return of countless Ancient souls to the Lifestream is going to have some unforeseen effects in the near future.
