No problem, and cool!
I see where you're coming from with the story, I like the mystery of it. It also did seem from that last cut off line of dialogue that there was a very real answer that was just being left off as a sequel hook. I'm not personally a fan of stuff where the meaning behind an action or a metaphor is entirely up to interpretation, because then it just seems like it was put in without any actual meaning. A mystery as the intended meaning, though, is far more preferable to me.
Very cool to know I wasn't just speculating wildly about the mystery character. And yeah, I figured Makyo wasn't canon because the way Zlonyth interacts with the party very heavily conveys it, as well as the decisions and power scaling of the firstborn being pretty inconsistent (one ending she rises and immediately destroys the matriarch and then the earth in seconds, the other ending she rises and fuses with the matriarch to gain a form that is able to be defeated by the party regularly?) so it's pretty clear that it only exists because the environment and extra battles are cool.
It was really fun translating, though like I said I never quite got to mastering the language, I usually had to re-decode it based on what was implied by the letters I already had memorized. One of the main reasons I started is because I didn't actually know there would be a translation machine later to help me out, so it not being originally intended makes sense.
