(SPOILERS) The Garlemald Empire was right

[Enkidoh]

Not to mention that their very technology is essentially a stand-in for, and in fact uses the same source as, magic (aka aether) - hence why it's called magitek, as magitek runs on cereleum which is a fuel rich in aether. As others have said, just because of a quirk of biology Garleans couldn't use aether in their bodies to create magic doesn't mean they're magic-hating muggles, which you seem to be advocating. The Garlean military after all freely employed mages in their ranks (draftees from conquered lands such as Ala Mhigo) so if they were really so obessively anti-magic, they simply would have not done so.

They also merely repurposed a lot of Allagan relics in their technologies as well instead of inventing them (again thanks to Ascian meddling), which, as we know often manipulated aether and magic itself in many ways. Garlemald's Corvoian ancestors might have resented the tribes around them being able to use magic to bully them and drive them out of their homeland, but they didn't resent magic itself, if anything they longed for that power themself - why else were there Garlean projects like the Resonant Project to try and overcome that limitation?

And to say nothing of mere Garlean farmers going to extreme lengths to be able to draw on magical power, by seeking out voidsent to fuse with and make use of their chaotic magic.

Corvoian

From one comment in Endwalker, the adjective given is "Corvosi".

Thanks for that clarification, I couldn't remember the correct term to use.
