[Spoiler] Did they forget Porxies exist?

[No_Nick_Needed]

As far as understanding the circuitry goes, we were told that they are based on Arkanist magic symbols, if I remember the talks with Krile's parrents correctly, so that'd mean that at least Limsa Lominsa is in a relatively good position to begin research into Electrope, without even the need to rely on plot convenience, especially if they team up with one of the technological groups like Garlond Ironworks, Garlean engineers or some Loporit technicians.

Though what we know of Electrope's inner working is so vague, any faction could potentially find a way to use it right now. Just take Gridania as an example, surely everyone's last candidate for meshing well with technology, but inside that Electrope flows elemental aether, and the Gridanians have based much of their culture on communicating with the elementals, so it wouldn't be entirely non-sensical, even for the most non-technological faction to work something out. That being said, they would however be the least likely to even make the attempt, in my opinion... well, apart from the dragons maybe. If you are naturally evolved to a point that you can fight even the Omicrons and Omega to a stand-still, you don't need such a "trifle" as electrope. ^^

Something I noticed while doing the sidequests to unlock flight in Urqopacha:

Nopli is referring to corrupted crystals, which he purchased from an Ul'dahn merchant. These crystals are visually identical to the ones seen in Eastern Thanalan, which are notably only a fraction of the surface-level remnants of the battle between Bahamut and Phoenix, iirc. By that I mean there's also a colossal amount of corrupted crystals beneath the continent's surface, see: Binding Coils of Bahamut.

The thing is, the practical use Nopli suggests for them? It's word for word how Electrope functions. Because of this, I believe Electrope's origin may have been similar. In fact, the way both function and their respective origins suggests to me that they may actually be akin to a planetary defense mechanism. Like, an auto-immune response to dangerously high levels of a singular element.

First off: Yes. Alisaie as far as we know can(!) summon Angelo when she wants. This is shown when bringing in Angelo to cure the tempered Kobold near the Aftcastle in the 5.4 or 5.5 questline.
Second: Porxies are a cure for tempering. But that solution was only reached after we tested it with Angelo on the Au Ra boy in the first. As a means to bring his inner ether into motion and equilibrium again.
We also learn that this method does only work when the environment is supporting it. Aka the WoL getting rid of the abundance of light in the First.
This leads into one problem regarding the population in the dome. The dome is made out of a good chunk of levin ether. So in order to cure them totally, the dome either needs to go or they need to move out into Tural again. To be cured there. Just using a porxie there, would only have been a temporary alleviation.
I agree though with the OP, that not bringing that topic of at least a temporary cure up at all in the story, feels totally out of place

I actually think it's presumptive that this is even curable via porxie. There's a couple ways that I could easily see that not working (not even 'failing', just 'not even baseline viable'). In ascending order of plausibility in my mind:

1. Tempering and light corruption is essentially the aetheric equivalent of an infection; that's an extant, foreign and directed influence on the body, something that can be targeted and quashed. If that lightning sickness is instead more environmental, akin to something like hypothermia, then there's just nothing to fight or remove.
2. Curing tempering and light corruption wasn't being done while the things causing it are still around. If you cure this imbalance of lightning aether caused by the environment, while the environment is still exactly the same... I mean, you haven't really done anything.
3. We know that once physical changes manifest, curing tempering doesn't help. (It's not made clear if it's 'we can't fix that part' or 'at this point they're uncurable'.) In those cases physical changes were visible changes, but I think an incurable medical disorder is absolutely a 'physical change'.

Are all these presumptive? Yes, and I'd certainly like a little side-story discussing it officially. But I think narratively speaking, it's pretty clear that we were being faced with something tragically unfixable; that there's nothing Sphene, or anyone in her kingdom, can do about this. So logically, a story about trying to solve this with a porxie wouldn't be about 'how does the porxie fix this problem', it would be 'why can the porxie not help, and how do we deal with that'.

Ima have to call bull shit on this. It fully explained this is caused by the body shifting to lightning side of the aether meaning that yeah porxie can fix this your body has to be align to balance. Now if it follows same rules as tempering meaning the time limit then yeah i can see this not working but yeah this can be fixed totally.

This is the same situation as the kid in the First but on a different degree.

They need to re-balance the aether but also regulate the environment. There's not point rebalancing the aether if the kid is going to live in a "polluted" environment.
The same way you can cure a smoker lungs but what's the point if they keep smoking?

It might be even a different situation, the kid might not even need the porxie and just a balanced environment

Can't wait for the source to have a great war over corrupted crystals and use it for ever greater weapons and ever greater technology.

It was odd for them to bring up a problem we likely have a solution to without us mentioning we might be able to solve it. When it was first introduced, I thought it was going to be a way to show Sphene we might be able to solve her problems without her having to just kill everyone, but I was naïve to think we'd try to solve problems with cooperation rather than violence because of the first half of the expansion.

However, they didn't do anything with it one way or another, so that makes me believe it will come up again in the future.
