A symbol challenge could be a fun activity. I'll have to bow out myself though, while I can draw a decent CC3+ map from existing resources, creating my own symbols is far beyond me. I need those stronger in the art to do that for me.

A batch of great maps from @Quenten . This includes his contest entry, which means all contest maps are now in the atlas. I've also updated the contest page on the atlas site, and handed out the forum badges to the contest winners, so everything should be up to date.

As far as I know, the only thing currently in my backlog is a set of maps from @Wyvern . Everything else is either processed and added to the atlas, or I have gotten back to you requesting some kind of correction or information from you. So, if you are NOT Wyvern, but still miss me adding something you've sent me, please notify me immediately, as that means I've overlooked something. People send me maps multiple ways, as attachments to forum posts both in this common thread and in individual threads, as email and as forum PM's, so it isn't always easy keeping track of everything. I do always post in the forum when adding new maps, either in this thread, or in the WIP thread for that map, so if you haven't noticed me posting about adding your map, it might be wise to check the atlas.

Anyway, here's Quenten's new maps

Considering this is a generic underwater style, and not made for a specific setting, I think it is safe to ignore things like breathing, just assume that any DM who is using an underwater style have a way in the system they are using to handle that issue.

When you install CC3+, it asks for the location of your data directory which you can put wherever you want, but the main program will always be installed to c:

However, it is the data directory that consumes space, the main program install is only about ~50 MB, even after installing all the add-ons, so this shouldn't even be noticable on your SSD space.

I disagree here. Those artistic maps do serve a real purpose in my games. I'm not that good of a descriptive storyteller, and an artistic map helps cover that up quite a bit. It lets me and the players agree on the look of the location, instead of they forming a very different image in their heads based on my limited description that they have. An artistic map can much more easily contain locations that may or may not be interesting which I love when showing it to the players, it's not as clear-cut as those traditional monochrome maps.

That said, if I am not showing it to the players, I am usually not mapping it at all. Most of the cities my players have visited don't have a map at all, because I don't need one. A simple list of locations is more than enough. Heck, even a lot of the dungeons don't have maps. I don't waste time mapping locations I don't need a map for. But if you feel you need a map for a location just for yourself, then yea, keeping it as simple as possible is good.
