I listened over and over and over again to what Isa said in Pangaean right before they spoke English. Here's what I heard.
"Niji stimo lah. Niji finidam dimio Set.
We all know the subtitle. (So you've done it. You've killed the God King. Congratulations."
Analyzing the similarities in the language "niji" seems to correspond to the word "you". "Gratuomos" is "congratulations.
However there is one part that I am very, very interested in.
"Niji finidam dimio Set."
"You've killed the God King."
"Niji" is "you" (or you have, in this case). And then there's "finidam". It sounds like the English word "finite" or its Latin counterpart "finita", which all of us know means something that can end. In this case we might attribute the thing ending as the God King's life.
Then we have "dimio". The closest thing I can find to "dimio" is the Japanese word "daimyo", which refers to the territorial lords in pre-modern Japan. Interestingly Saydhi lived in an estate with Japanese architecture and cherry blossoms; anyone, any stranger unfamiliar to IB2 will obviously and naturally see Japan in Saydhi's estate. How it's built with gardens, raised above the ground like a Japanese castle of old. Also, there was not just one daimyo in Japan. Each had territories, and either lived with each other or fought each other. Eerily similar to our Pantheon or 9 Ruling Houses, where there were Deathless, each holding their own territory (Saydhi bordering Raidriar's).
Finally, the word we've all been waiting for. "Set". Lots of theories here have attributed Siris to Osiris and Raidriar to Set. Well there it is. "Set" is probably the Lantimorian word for God. Remember that Isa is a foreigner to Lantimor, and she probably was speaking Pangaean local to Lantimor (remember how she told Siris that where she came from there were seventy ways of saying one is hungry (please correct me on the number of ways if I'm wrong )). Seems to confirm the analogy between Raidriar and Set.
So, if we directly translate it, it becomes:
"You have made finite the infinite, immortal and all powerful territorial lord."
This makes sense, as a God is usually depicted as immortal and all powerful, but as Raidriar is also the ruler of the land he becomes a king or a daimyo in his territory.
I love how Isa said Set. Brought chills down my spine.
Please comment if you have any more ideas.
