Tidbits, kiddos!
After 5.5 yielded little in the way of answers, I did remember the white sphere (Seed of Creation / Destruction, or just "Seed" for short) had Drakengard-verse angelic writing on it, so I looked up the script and tried to translate that... but it was just repeating the same character(s), so the effort didn't seem worthwhile. Interesting that the characters translate to the base code for DNA, but I don't see what value that knowledge is.
On the other hand, there's lots more "angelic" script used in the fights against the False Idol and Her Inflorescence. I doubt it would provide any additional context, but if someone wants to translate it that's a good lead. (I'm not quite that dedicated, lol.)
One last note is that when Her Inflorescence summons trains to run over the party, the text box doesn't use her name. Instead the line(s), which include stuttering and trailing into Japanese characters, are "spoken" by what translates from hexadecimal to "Voice" (766F696365). I don't recall seeing this happen elsewhere, and it doesn't provide any context, but it's a neat little thing to notice.
One more week and we'll see if there's any big payoff in Konogg's last datalog, I guess.
