This was the best MSQ patch in recent memory. It's great to see the storytelling evolving, especially in all the little non-verbal details. The answer choices were great this time around, with some comedic gems in the reactions. The new Unending Codex feature is fantastic from the standpoint of making lore more accessible to the playerbase, and reminds me of FFT's Brave Story logs in format.
MSQ:
It looks like there's something significant involving the moon(?) on the 13th, given that it gets highlighted in both of the cutscenes with Zenos' avatar. Given that the avatar describes the thirteenth as a 'world bereft of saviors', I'm guessing that they belong to a different faction to Golbez(?) and the Four Fiends. Speaking of which, I liked the tip off with FF4's 'Somewhere in the World' track running in the background as well as Scarmiglione's lisp. I have a feeling that, given the way that they speak of 'salvation' of their star, that they're probably the old comrades of Unukalhai and Cylva who were aetherically corrupted by the Flood of Darkness, similar to Ardbert's companions on the First. Looking forward to Rubicante in particular, he was a fun personality even back in FF4.
It looks like Estinien is channeling Batman in more ways than one. The fact that he's starting to show a bit of fiscal awareness after living in Thavnair for a while was a nice touch. It was interesting to glimpse some of the hidden motivation behind Y'shtola's shard research as well. Some of her optional banter lines were really well done. I think one difficulty at the moment is that they don't have enough trust characters involved just yet to do a complete narrative split, but it's early days. Also nice to see them situationally acknowledge if you've recently made a pact with a voidsent yourself.
Azdaja's story and the corresponding Meracydian lore drop was an excellent plot hook. The First Brood are a welcome break from being oversaturated with Amaurot.
Myths of the Realm:
Much like Pandaemonium, we don't have a whole lot of new information yet to work with. The fact that the Omphalos/Navel is located over Lake Silvertear is interesting from a symbolic standpoint, especially if there turns out to be a connection made to the Lifestream in all this. I'm curious about the distinction that Byregot makes about being not being 'summoned', and how Nald'thal explains that Louisoix's summoning was something else altogether. That being said, I wonder if that just applies to his attempted containment of Bahamut or if it includes Althyk's teleportation/time jump as well. They look reminiscent of transformed Ancients, so perhaps that could explain why they were never actually summoned in the first place.
