Just some of the names he spotted that were listed as actual areas. He saw some other areas listed (not within Insomnia), marked as dungeons but he couldn't find anything that goes with them across the data, so he's not sure if it's placeholder, unused or whatever sort of content.
The mods on the Reddit seem to be really into lore stuff, one of them posted up a topic with photos around showing The Vesperway listed. I remember there was a conversation, and I agree, it does sound like a highway.
Uh.... To cut it short without saying anything, no. If what OG sent me ends up being correct, it's one of the existing ones and also answers a couple of plot points. Again, spoilers on it so I think it should be left at that, given OG didn't want to do a massive information dump and potentially ruin anything. He seemed to have gotten annoyed about the confusion on the quests, and lack of news.
