There's some circumstantial evidence that says Mitron was originally female. In addition to their true name being Artemis, there is also the fact that someone tied the voices from the crystals to their speaker and the Mitron voice was female in tone.
Combine that with Loghrif not recognizing Mitron during their reunion and you could make the case that Mitron has always been the old girlfriend, if you so choose
Yep. And using this as a springboard I'll elaborate on my shitpost
In other languages, Ultimecia is usually translated to Artemisia, from Artemis. The E12 boss is based on a real-world statue of Artemis. Taken all together, it seems pretty likely that this Ascian is meant to be a very uniquely FF14 parallel to Ultimecia. The only thing out of place is that E12S gives The Extreme to Gaia instead, but Savage isn't canon.
Kinda big brain stuff but I honestly don't see it as much of a reach. There's too much going on here.
