The Rising Event - Lore Discussion

[Alberel]

There's an area in each city, with some NPCs who you can talk to, but Limsa is the main one for the quest.

Also, in one of the minstrel's songs, was he talking about upcoming events, I remember he mentioned something about snow covered highlands and gates "yawning" open, possibly referencing Ishgard.

Before the Echo was triggered he recited a verse of one of Louisoix's prophecies that we'd already been given. That verse pertained specifically to the current events we're seeing in Coerthas, and presumably Shiva.

Once the Echo hit us and we went to the aetherial realm he gave us a new verse of the prophecy, however, which appears to be about the expansion. As you say that talk of opening gates was almost certainly a reference to Ishgard. There was reference to an old enemy as well, which I would assume to be Lahabrea. It wouldn't surprise me if the final confrontation before the expansion is a rematch with our favourite Ascian.
