I love how that central corridor is made to look snake-like, culminating in a room that looks like a serpent's head. But I especially like the two wall extrusions near the "head" also look serpentine.

Can you explain how the top structure relates to the bottom (or is it a secret?). There doesn't appear to be any entrances to that part. Are they secret? Is it accessed magically? Is it on the same level, north of the larger structure, or another level higher or lower?

I'm very intrigued by this.

Awww, that’s very kind of you, @Calibre. Thank you.

Okay, I changed it on the Floors 3 and 4 maps, too. While they aren't suitable for the Atlas in their current forms (though I could always tweak them to be a museum or other building), I would still like to offer them up to any Game Masters who would like to use them in whatever campaigns they're in. (I will also post that message to the FB group to reach a different audience than the forums.) For anyone who would like to use them, here are the FCW files with my blessing.

Went in to change the outside landscaping in the second floor file and noticed that I forgot some of the windows, especially on the main entrance side. @Don Anderson Jr., does this achieve what you recommending with the landscaping for the higher floors: keep the fence but eliminate the foliage? I kept the fence and added a Solid 20 fill (which I could change to Solid 10 if it looks too strong).

I forgot to answer this question:

They are all separate maps. I have done some where there are navigation links to open other levels, and others where it's all in one FCW with layers hidden. In this case, they are separate files but I didn't add navigation links because I liked the sleeker look without them.
