I rewatched the final curtain video for the closing of 1.0 and it seems to me that all that crystalized, corrupted aether is probably the result of the conflagration between the final spell used by Louisoix and the unleashing of Bahamut energies. We see clearly that when both meet, the meteor stops just before reaching the ground, and long coils of magick soon turn into crystal (which are still here today, pointing to the sky).
