OP should be about finished, I think? FR is fixed, I think? (Thanks, Nalfein!) JP transcription is in (Thanks, Marko!), and I think the biggest hint is there. See the old kanji for "crimson" and "azure"? Those are indeed the same glyphs used for Crimson Liberators and Azure Heavens of Ishgard, the JP titles of 4.0 and 3.0, respectively.
So, Ala Mhigo is a powderkeg; we knew that. And if that keg don't blow, then there's no 4.0. (I made that up.)
It seems to be saying that the conflagration in Gyr Abania will drag Ishgard (and thus the Eorzean Alliance) into the fray.
It could also be a coincidental use of azure, of course. This expansion does include swimming and diving. But let's focus on Occam's Razor and wait for the third Fan Festival's reveals before we put that over Ishgard.
