I'm slightly concerned at what role The First will play outside of this expansion. I have a feeling we'll never see the people of The First again and this will all become some kind of sideshow. Or worse The First will show up as some kind of interdimensional army and the story will get hopelessly convoluted. But who knows, I've only just finished the first dungeon. As much as a mess Stormblood's story was, it was at least building onto the ongoing story against the Empire. Ishgard, Doma and Ala Mhigo were all nations developed for the on-going conflict of the Empire but it seemed The First exist completely outside this story.
