I think I remember that cutscene, where a certain Sharlayan scholar uses very estoeric real world scientific words to describe aetherial effects.

The specimen is more than a simple manifestation of elementally aspected energies -- it is, rather, an aetherial lodestone whose facilitation of both the absorption and transmission of distinct-frequency NRR-type harmonic vibrations has been observed to promote aetherial amplification.

The resultant neuro-harmonic disturbance allows for a highly unique emittance of CPRS waves that, instead of radiating outward with a determinate factor of dispersal, instead resonate inward at a frequency so labored, my estimates place the rate of VRT decay at upwards of several centuries... though I must admit I lack sufficient variates to complete a truly comprehensive graphical assessment.
Idly, only semi-related musings: In this setting, aether itself is not magic. The study of aether in its natural tendencies isn't magic. The textbook definition of magic is manipulating aether outside of its normal, natural tendencies. In that respect, I imagine that's what technology vs. magic boils down to in the setting. Technology, even magitek, uses aether in ways that are within "natural" and predictable models. Magic is another field entirely that plays with whole new rules on how to manipulate this natural force.

In that regard, I'd say that, at least when it comes to aetherology, Eorzea probably has much more of a better hands on practical on it than Garleans do, while Sharlayans reign supreme in tackling it scientifically.. Eorzea's had centuries of working with an aether-rich environment to have a deep appreciation of the inner workings of aether, which means that they have an understand of a certain aspect of the universe that Garlemald doesn't really have. That's not to say that Garleans don't know about aetherology (after all, they DID create an artifical Echo, something that not even the Allagans are able to accomplish).

Again, only semi related babbling, but I find this kind of topic in fantasy settings to be fascinating. TinyRedLeaf's reminded me about Eberron, IMO the best D&D setting out there, in that it treats magic as a kind of science. So you have stuff like magic-powered robots, airships, trains...GREAT.
