Mobile Eden halted and put into stasis mode at Nabaath Areng was one of those "I never made that mental connection but it makes perfect sense and can't believe wasn't obvious".
Maybe it's because I adore "For Want of Nail" style Alternative Universes as long as they aren't too shoddily written, but I am enjoying various tidbits about Pre-Flood Norvrandt as I knew that I would. One of the elements sticking out to me is the population origins for several migrations matching up to Eorzea- that the Galdjent were once again a mostly piratical seafaring folk from the northern sea that settled previously in Kholusia's island as well as Voeburt surprised me, though that the Mysteel were outsiders with vaguely nodding to Meracydian origins and that the Elves were claiming first settlement of 'Eorzea' from a centralized location did not.
The Qitari quest lines already told me that the Ronkan Emperor was Ronso- but it has not clarified if said Emperor was male/what the succession rules were. Which I do find interesting as a question because of the Queenship of the Hrothgar. That the Empire fell 3,000 years ago seems a bit long, but it does make clearer their role as the counterpart to Allag, solely in the status of great distant fallen Empire.
Alas the Garleans couldn't have received the Galdjent's magic-nullifying tattoo knowledge instead of the poison pill of Allagan magitek- though I am most curious about the clans and particularly the Cedarfords, the newly recognized clan without electorate powers (was that about to change?). Probably because the power imbalance was 2-3, unless the royal clan also has an electorate vote, which I'm going to assume so. Very German.And are we to assume an Ishgardian-like class divide in the split between which refugee groups fled to Eulmore versus the Crystarium?
Perhaps the biggest shocker? Tolthewil's character. The elven nation had virtually no info and what little it was didn't paint a glowing picture, so that they were the often cruel and controlling tyrants after Ronka's fall wasn't surprising. But Tolthewil and his knights in the Grand Cosmos seemed obvious as the sly nod to Thordan and the Heaven's Ward and Tolthewil the likeness of what Thordan XIV looked like in his youth (which helped to explain Aymeric a tiny bit more). Okay, so the blond hair coupled with Haldrath's blonde hair makes it obvious that he's the counterpart to Thordan I. But! Honorable nice guy that fights against injustice, genuinely good king. Whodathunk.
