A quick note on two of the new islands that you can see have been posted in this thread
Blackreach Island seems to be Asterios Labyrinth posted by Tobi, seeing as it’s the only one listed that the two built together and it’s Tobi worked on Asterios with Misinput, as there’s an image of what is presumably it you can see through the blur
One of the others (likely Gloam Ruins as I don’t think Cedar Arch and Thrylos Crossing would be them since the island names don’t fit as much) is likely Sundered Crowned Fortress, seeing as one of the images is literally one of the ones in this thread
