This quote right here:

When the sixth sun will have set and the seventh moon shine in the sky, the ocean of clouds poured a rain of fiery flames and shadows fatal burst forth from the depths of the earth…
The “Seventh Purification” predicted by Mezaya approaches…
You who are in search of truth… wake up and put yourself against the imminent threat…

It's gonna be a huge disappointment not even have the end of the world implemented BUT:

See, but I think that's just a metaphor for the Sixth Astral Era (sixth sun) ending and the Seventh Umbral Era (seventh moon) beginning. The seventh month in the Eorzean calendar is the 4th Astral Moon. :/
