AntiTower Speculation

[Cilia]

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.

I actually wouldn't be opposed to someone going Kefka, but would only really be OK with it if they used the Black Mages mix of Dancing Mad for the boss theme.
The way I see it, one of two things are going to end up happening with the Triad and Garlemald:

• Using information from Azys Lla, the Garleans replicate the magitek infusion from VI, albeit at the prototype stages Kefka used. van Hydrus is the first test subject, but like Kekfa it goes awry, and he goes completely butt-kupo insane and we have to put him down. Varis escapes with the tech, though... now the Garleans can use magic, and we have to deal with them.
• Same as above, except Varis uses himself as the test subject (cuz, as leader, he has to be the strongest!). Again, it doesn't work and he goes butt-kupo insane, and van Hydrus pulls a Leo, defecting along with the VIth to Eorzea but retaining his distinctly Garlean identity. We have to fight Varis as the final boss of 3.5.5, but he escapes to Garlemald, and again the stage is set because he has an army and is completely off his rocker with power.

As for why Allag is handled as a bigger threat? They aren't really, it's just that all the crap they left lying around is extremely dangerous and always getting into the wrong hands. Almost literally everything that goes majorly wrong is because "Allag something." Dalamud, Ultima Weapon, Syrcus Tower, Omega, Azys Lla... pretty much everything can be blamed on (the Ascians egging people on to discover) leftover Allagan crap. The only thing that can't be is the Void Ark.

The problem with this(and its a fixable problem, really) is that it starts to make any non allagan threat seem minor, the allagan stuff is just wasted on Eorzea, when in any other situation it probably wouldn't be.

Omega kinda plays into this, assuming it doesn't saunter off to Garlemeld while no one is looking. Just what is Eorzea doing with all the allagan stuff that happens to be found on their territory? With the idea of faving such a powerful enemy in war possibly in the works, could we be tempted (or desperate enough) to go down the same road they did?

What are we doing with all the Allagan crap lying around? Nothing, probably, because we've learned from the Garleans' example that messing with Allagan crap is bad news bears. Every time they've come at us it's been with some Allagan tech, and every time it's backfired in their faces spectacularly.

Dalamud not only didn't end Eorzean resistance, it exploded and let out an Elder Primal that proceeded to devastate the land in short order.

Ultima Weapon did what it was supposed to, but also had a nuke capability van Baelsar was unaware of and didn't like. It also wasn't enough to intimidate or overcome Eorzean resistance (though we did need a direct intervention from Hydaelyn Herself to survive Ultima).

It's primed to blow up in their faces on Azys Lla too, with all the VI references suggesting someone's gonna go nuts and/or devastate the world.

The temptation is there for us to go down that path, but since modern Eorzean civilizations are rather spiritual, I don't see it happening any time soon. It's cited that part of Allag's cultural degeneration was due to the fact they believed themselves absolute masters of the world and disavowed the existence of deities, rather like Garlemald aspires to be, leading them to doing whatever they wanted without regard for morality. (I'd question how atheism makes people depraved monsters with an insatiable lust for conquest, but this is neither the time nor place, and the Allagans and Garleans sound more like anti-theists than atheists. Besides, Hydaelyn has proven herself capable of direct corporeal intervention, so at least she definitely exists. Jury's still out on the Twelve.)
