My attempt at the FULL lyrics for the Garlean (stolen) anthem.

[YianKutku]

It's important to remember that most of the Castra built in Eorzea were built by the Rogue XIVth; I'd need a Legacy player to verify but I don't think Castrum Occidens was around during 1.x.

While Anonymoose is working on his edit, I'll just mention that this is an excellent point. I have no idea what Legacy was like, but based on the Lorebook, it implies that up until the Calamity, the only Castrums on Eorzean territory were Castrum Novum and maybe Castrum Abania. No idea if Castrum Oriens was actually built back then (I recall this topic having been brought up before).

Of course, maybe the truth will be much deeper and more confusing.

While Vylbrand may be safe from Imperial aggression if the Lore panel is to be taken completely literally, the fact that Limsans have pirated engaged Garlean vessels in "spice trade" for quite some time could easily make them susceptible to it. Even if they didn't, looking at how things were for the Confederacy prior to our intervention their way of life would be greatly impacted, so it's not as if the Limsans would be unaffected by Aldenard falling completely under Imperial control.

Entirely true. If nothing else, the Garleans would probably want control of the artificial Allagan island/testing ground that is Seal Rock, so I can't see the Garleans ignoring Vylbrand like they do for Hingashi (Confederacy notwithstanding).

Old Sharlayan may be spared, though. At least until they develop something the Garleans decide they want.

EDIT to add:

Even if Garlemald has little interest in holding outlying islands, Limsa Lominsa was one-third of the Alliance. When Gaius resurrected Castrum Novum as Castrum Centri and established peripheral castra radiating out from it, Vylbrand couldn't be ignored.

Which does bring up speculation on what Gaius's plans for Ishgard would have been. Ishgard used to be part of the Eorzean Alliance (and Ala Mhigo would probably have plenty of histories about that), but then holed up in Coerthas to continue their Dragonsong War, ignoring the Empire.

But then the XIVth tried building Castrum Aquilonis in Coerthas anyway.

But then they abandoned Castrum Aquilonis half-built after complaining about the climate.

I can't imagine Gaius to be the sort of commander to leave a potentially hostile force unchecked, especially when one side of the Dragonsong War consists of, well, dragons, ie the beings that so decisively stopped the Empire's advance into Silvertear Lake.

So would Castrum Aquilonis have been resurrected and completed? If so, why abandon it in the first place, when the XIVth managed to construct castra everywhere else, including Castrum Marinum in the Rhotano (ie well within territorial range of the Lominsan Navy)?
