Here are the first two levels of the basement. Sewers still to come.

Basement 1

A wine cellar in the northeast corner is conveniently close to the stairs, so that the wizard or their staff can slip down for a few more bottles in the middle of a dinner party. Continuing clockwise, the other rooms are a freezer, a larder, a storeroom, and in the northwestern corner, a refuse pit is used to throw organic, wooden, and metal waste for disposal in the sewers.

Basement 2

The second level of the basement doesn't appear to have much. A corridor heading west leads to stairs that descend into the sewers. To the south, a cavernous chamber has been turned into the wizard's grotto. River water has been pumped in to make a man-made pond, heated to a pleasantly cool temperature by a few warm luminescent crystals. A second, larger pool is warmed by enough luminescent crystals to keep the water as warm as a hot bath. The room is lighted by clusters of luminescent fungi. On the western side, a spacious WC also doubles as a changing room.

But wait, there's more! This floor also has two secret passageways. One near the stairs leads to the Wizard's secret treasury chambers. The outer chamber is used for coins, gemstones, and other valuables. The second chamber, accessed through a short corridor protected by a Glyph of Warding holds the Wizard's magical treasurers. In addition to being about 30 feet underground and carved into the rocky hillside, the treasury is protected by marble walls that are five feet thick. Between these walls and the rocky cliff is another foot-wide wall of lead to protect the room against scrying eyes.

Another secret passageway north of the stairs leading to the sewers leads to a cavern, through which a secret Teleportation Portal can be accessed. The southwest corner has been sealed by a Wall of Steel, protected by another Glyph of Warding. If you get past that, the passageway quickly dead-ends into a pile of rubble.

The Wall of Steel and the rubble can be hidden using the RUBBLE layer:

FCWs

And here are the FCW files for these levels. (Remy, this is not the official thread for submitting to the Atlas. I will create a new thread with these maps properly labeled and described, plus a village map to come.)

I saw "favorite setting" and immediately misinterpreted it as a CC3 setting, like the sheet effects (of which my favorite is the Color Key cutout effect). Every campaign I've ever been in has been a homebrewed world, occasionally supplemented with commercial modules dropped in as side quests. I first started playing in 1979, when Greyhawk was the only world around, but I only have a passing familiarity of Greyhawk and Forgotten Realms.

But I've been invited to join a Pathfinder campaign set in the world of Golarion, so I'll be learning a lot more about that world soon.

I did not know that Waterdeep was designed with Campaign Cartographer. That's really cool.

And if I didn't already share it, here's the "Above" FCW:

Yes, absolutely! I kinda forgot about that once I found a place in the Atlas for them. But as that may take me some time to submit, and then Remy some time to process, here they are in the meantime:

One thing to note: I found my computer getting kinda sluggish with some of these until I hid all of the outside stuff while working on the rest. (That cleared up when I rebooted.) To deal with that, I created an "OUTSIDE" layer for each of these and put almost everything that wasn't inside the tower on that layer. If you're customizing and find it slow, hide the OUTSIDE layer while you're working and that may speed things up.

Turret is done, and with it the entire above-ground portion of the tower. There are several basement areas (cold storage and wine cellar, sewers, dungeon!) that still need to be mapped. My hope is to finish it all off before the end of the month.

Eighth Floor

The 8th Floor of the tower is the first floor of the turret, plus the roof area (protected by crenellations) of the main tower. The turret has arrow slits that can be closed off inside with metal shutters. (In looking at the arrow slits, I see they are not quite like the ones on lower floors, so I may adjust them.) The spiral staircase extends up one more level.

Ninth Floor

This floor provides arrow slits elevated above the roof of the main tower. The spiral staircase ends here, but rungs mounted on the wall allow for ascending to the "bell tower" above.

Tenth Floor

It's more of a light house than a bell tower. Luminescent crystals radiate light that can easily be seen for miles around. On holidays and special occasions, the wizard can use simple illusions to change the color of the light to match the holiday's traditional décor.

You may have noticed that these images now use the title "Tyr Alomere" instead of "Wizard's Tower." I have decided where I'd like to home it in the Atlas, a wizard's tower that I had placed in the Gold Coast area of Doriant that I mapped for the Atlas (circled in yellow in the two images below).

I will need to design the small village the tower is in first. Do you think I need to do a more regional map, or will the village with the tower suffice?

Here it is on the Gold Coast:

It also makes an appearance on the edges of the regional map of Gongodûr -- it's in the Kingdom of Vacuria, but on the edges of Gongodûr:
