5.0 speculation
While Garleans have been in all the expansions, we've only ever seen their conquered fringes, never their home territory, I imagine the Imperial Capital will be a sight to behold. We've also grown used to the Garleans being the 'baddies', however, I forsee an Alliance with the peoples of Garlemald against Varis and Elidi-nos. Unlike Stormblood, we're not trying to unleash a storm or a war, we're fighting against the very agents of chaos themselves, the Paragons, the Ascians. I think we will wont be fighting the Garleans, rather, we'll be fighting alongside the Garleans.
