Quote:
Ne'er til land consumes sun can sea bear moons.
Heavens spew crimson flame, hells seep black dooms.
Stray seeds quicken in ash's grey embrance.
Valiant blades forged under the twelve's good grace
The sun can only be eclipsed by the moon, or (in FF terms) a closer as of yet unknown planet. If the sun were to be hidden in an extended eclipse, the moon would also be darkened.
If it means the sea could not possibly reflect the moon's perfection without the blunting influence of a darkened sun, then it might make sense.
Stray seeds being quickened in "ash's embrace" would appear to mean some kind of darkness, twilight, or like you said, a volcanic ash.
The sky flames and hell dooms no gahdamn idea.
YOSHIIIIIDAAAAAAAA!!!
