So, I've tried to look them up, but can someone explain what Reyvateils actually are? Please?
Reyvateils are an artificial species from the Ar Tonelico franchise. I'm obsessed with it, and it's surprisingly compatible with the universe you're describing here, so it pops up a lot. Especially when
@justinkal and me start bouncing ideas back and forth.
It's off-topic, so I won't go into too much depth; we have a
discussion thread for that sort of thing. To answer your question... there'll unfortunately be a short history lesson.
On Ar Ciel, which is a human-populated planet in that universe, there had been a cold war ongoing between two massive alliances for, oh, at least a few hundred years. Reyvateils were created with two distinct and somewhat incompatible goals in mind: To be a new humanity, a
better humanity that wouldn't so easily go to war, that'd be smarter, live longer and be generally nicer to each other -- and to create artillery pieces that could be used to gain an advantage in that same cold war.
You see, they had recently discovered the scientific rules underlying the (not very powerful) magic they'd used throughout all of history, and as a result their civilization was quickly evolving from a near-future high-tech civilization to a high-grade magitech civilization which would probably compare well to Al Hazard.
Attaining powerful magic turned out to require pure souls -- "pure" in the sense of being made of a single element, not a moral evaluation. Reyvateil are, thus, artificial intelligences with artificially created souls. They were also researching the nature of the human soul, but hadn't quite figured it out yet... sadly, the cold war shortly turned hot, and the planet was nearly destroyed.
It turned out that sufficiently powerful, scientifically applied magic was enough to kill the soul of the planet. Which they hadn't previously known existed.
Reyvateils are AIs, but they were built both to
act like humans, and to
have roughly the same subjective experience as humans. Which is good, as long-term it seems like they'll be outright replacing humans...
But sadly, you kiboshed the idea of building Reyvateils on, I believe, the previous page.
