I don't know about that since Emet-Selch's reliable bucket list of locations for us to visit mention new areas in Eorzea, with it and Blindfrost being the only remaining locales.

But, yes. Honestly it's been my fixation lately in trying to find every crumb of Gridania and Shroud details I can.

I want the devs to really sink their teeth into the vacant holes in Moonkeeper and Duskwight lore and society, in particular. What little we have of is incredibly interesting, and Gridania's special brand of xenophobia is still going strong, and our Scion allies with the best connections are dead or helping run their direct rival nation of Ala Mhigo. Shoot, we know little of the Autumn War beyond Ala Mhigo getting their stuff handed to them and that any Ala Mhigan refugees looking for shelter in Grid are very unlikely to be accepted by the elementals because of said war. (You can find an Wildwood lady talking and showing off the carpenter's guid to a Highlander women, so some were allowed in, but she's the only vague example of such.)

I would lose my whole little mind if we actually got to go into one of those remaining Gelmorran settlements that are implied to still be around, but barely be hanging on.

Gridania's got all the potential for lore and more expansion over the other two cities because of how the MSQ has worked out. The Scions used to be based near Ul'dah and had many dealing with their leadership, and we've gone back to help Limsa with their primal issues and tribe relations several times. Most times we've gone to Grid it's to ask them to leave with us or work along side everyone else. Little one on one or things happening in Gridania's borders.
