Quote:
Far to the south of the Three Great Continents, beyond the equatorial line, lies the second of Hydaelyn's three landmasses-Meracydia. Five millennia ago at the close of the Third Astral Era, the Allagan Empire [...] began an invasion that would end with nearly the entire continent being rendered a wasteland. While some areas remain uninhabitable even today, those which have been repopulated remain recluse and very rarely welcome contact with the civilizations of the northern hemisphere, ofi:times attacking any who approach, whether it be by sea or by air. Because of this, very little of the region is known, including even the most basic of geographical information.
Just from this blurb we know that the inhabitants do in fact have the capability to take out airborne invaders, so they must have access to significant magicks or technology. Does that include fending off Garlemald as well?
