The great thing about the Dalamud shard in Eastern Thanalan is that you can see an actual entrance to it and a path leading to it, but it has been blocked off by crystals. It means they planned to release a lot of future turns to coil. The whole area looks amazing.

I was hoping this is where 6-9 will be but it is certainly in North Shroud as the live letter confirmed.
