Sundering stuff established in the Q&A

[Cleretic]

I am curious where the idea of Emet-Selch not understanding Zodiark's mechanics comes from.

He gets the concepts, but remember that he wasn't the dynamis expert, so he might not have gotten the whole thing. Perhaps 'probably didn't understand' is understating his odds of knowing, but he didn't definitely know.

But even if he did, why would he go into those specifics for us? He was telling that story largely just to make us understand his pain and woe; he doesn't need us to understand its mechanics, he needs us to understand its cost and effects. So he told us the effects rather than the intention, because the intention doesn't matter for his story.
