I always did think it strange that an empire that fell 5000 years ago is handled as a bigger threat than the one on our doorstep. If Regula van Hydrus is going to pull a Kefka, perhaps the solution to Garlemald's threat-level issues would be solved if he unmasked himself as an Allagan, and head of whatever internal faction gave the green light on van Darnus's Meteor project. Suddenly the deactivated Allagan tech we've been sighing with relief at comes alive, in fully capable hands, and the last Allagan descendants unite to usher in a new era of peace by ending the pointless conflicts that divide us, by force if necessary. The remaining loyal Garleans take a step back and realize "Oh, is that how we look to the rest of the world?" and we enemy mine our way through the gates of Garlemald.
