Final Fantasy Crystal Chronicles
The Moon God is the cause of the miasma.During the final battle with Galdes look at the arena. It looks extremely similar to the Meteor Parasite doesn't it? Assuming multiplay is canon, it also shows that people who have had their pasts altered sometimes "relapse" and that alternate selves can even manifest. The now good adviser even comments on feeling "another me" when Lich is around. And if they're still around in the new world. Surely someone as powerful as the Moon God won't simply disappear. It was the cause of the Meteor Parasite, possibly meaning that Raem is to it what Lady Mio is to the Great Crystal.
Amidatelion from Crystal Bearers and Amidatty from the original game are the same person.Similar names aside, according to what's under the Humans by Any Other Name entry on the page, it's certainly possible that he/she/it could've lived this long.
Yuri and Chelinka are responsible for the monster society in the My Life series.The reason that the monsters seem far less Always Chaotic Evil, is because the twins didn't think it right to just erase all of them, and so instead gave them the ability to make a Heel-Face Turn.
Crystal Chronicles is the Dark World for the original Final Fantasy.This came up when I was playing Crystal Bearers. CB is about 1000 years after the original and miasma streams all still popping up. Therefore it seems that the FFCC world tends towards perversity or destruction with only the Great Crystal keeping it in check. This naturally destructive world makes a nice compliment to the naturally safe FF world. Here are the various parallels
Yukes reproduce asexually.It's hinted at in the games that Yukes have no biological bodies and are literally souls sealed in suits of armour, much like Alphonse from Fullmetal Alchemist. Word of God states the other three tribes can interbreed, but Yukes cannot interbreed with any of the other tribes. However, there are Yuke children in the game, such as your younger siblings when you choose to play as a Yuke. Because of this, it's likely some sort of elaborate magical ritual is involved in the creation of Yuke children, since after all, they are the most magically advanced race in the games. This would also mean that Yukes' genders are purely aesthetic.
Yukes wear the armor they wear because they are So Squishy.In every game of the series, Yukes, even in the armor they wear constantly, are The Glass Cannon and/or The Squishy Wizard. If they are fragile in armor, imagine how much more they would be without it. They wouldn't have survived long enough to become a major race if they die so fast, hence why thier superior minds decided that they should have armor.
