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).

And not that we had any reason to think Winter Trail/Winter Village would be different, but just for fun, here's a sliver of an alpine village.

These are the sewers for Elmsbrook, a town in the human kingdom of Powys in my campaign world. They’re intended to be fairly representative on the sewer systems in my kingdom – smaller villages might have a simpler system, but larger cities will have the same basic layout, but with more extensive canals.

I was hoping to get this done the same month that Sinister Sewers was released, and I barely did it. I still have work to do, and advice to collect, but thought I would post where this stands.

By the way, Sue: it worked putting everything for each level on its own layer, making it easy to display or hide different levels as needed.

In addition to using the symbols and fills from Sinister Sewers, this also uses a few things from Marine Dungeons (particularly the stairs and the bell at the bottom of the pit), and a few things from Forest Trails (leaves, the trees along the beach, and maybe some of the fills) and Creepy Crypts. Also: Sue spent a lot of time helping me come up with a technique to show clear water, but it really worked best close-up. At this scale, it made it look like black water. I ended up using a water fill from Creepy Crypts, but on its own water sheet with a 50% transparency effect added.

In my campaign world, fastidious elves have long understood at a high level the correlation between hygiene, sanitation, and the spread of diseases. (Even if they don’t have the tools to study microbiology and virology, they can study commonalities in infected populations to identify vectors of disease.) Dwarves first developed aqueducts and sewer technology. And it is said that orcs pioneered the use of flesh-eating oozes for waste management.

Oozes are amorphous creatures with an intelligence no greater than an ordinary garden slug, flowing through subterranean lairs to devour any creature or object they can dissolve while shunning things that provoke their flight reflex, like bright lights and extreme temperatures. I have made a few tweaks to oozes in my campaign world to make them better suited for deploying in sewers. I added immunity to poison and diseases. I also added a weakness: sunlight hypersensitivity where, like vampires, they can be damaged by exposure to sunlight. (This is why they avoid bright lights: a bright lantern won’t harm them, but it still triggers their flight reflex.) Sunlight can kill an ooze, causing their acids to neutralize and their bodily remains to collapse into a nutrient-rich goo that farmers often use to fertilize their crops.

Some items of note about specific oozes used in sanitation systems. Gelatinous Cubes can dissolve nonmagical soft tissue and vegetation, leaving behind undissolved bones, metal, glass, stone, and magical items of any sort, along with excess water stripped of anything edible. They cannot climb but can move up slopes with a grade of 25 degrees or less. Moving up a slope with a grade of 10 degrees or more requires the Cube to expel any indigestible materials or excess water. Black Puddings are far more dangerous. In addition to dissolving soft tissue and vegetation, they can also dissolve nonmagical bones, metal, but cannot dissolve glass, stone, or magical items. They can also climb any surface, even upside down. Sanitation workers employ bright lights to keep Black Puddings from escaping (and an ample food supply keeps them from seeking to escape). And finally, I created a new ooze called a Voracious Sullage. It’s a slow-moving, weaker version of the Gelatinous Cube, unable to maintain a cubic shape. It tends to stretch itself across small waterways so that anything edible flows to it (and anything it can’t eat gets expelled on the other side).

Here's a quick summary of how the sanitation system works. More specifics for each level of the sewer system will follow in the comments.

Surface (not shown): Storm drains at the intersections of major streets, with a manhole cover at one of the corners than allows maintenance workers to descend using rungs. There is also a large Waste Management Facility where residents can dispose of large objects that cannot be repaired or repurposed (such as items that cannot be chopped up for kindling). Maintenance workers throw these items into a giant pit nicknamed the Great Maw that is about 140 feet in diameter. The surface of this pit is in a building that is covered at night but open to the sky during the day. Bright luminescent crystals are placed near the mouth of the pit to frighten away the Black Pudding at the bottom of the pit.

Level 1: This level is immediately below the surface. Storm drains at major intersections deposit rainwater (along with other debris) here, where they run off to chutes that bring wastewater to Level 2.

Level 2: Wastewater from Level 1 is deposited here, where it helps push through human waste from outhouses and latrines that are connected to the sewer system. This sewage flows through chutes down to Level 3.

Level 3: Waste brought in from Levels 1 and 2 are treated here in two great chambers called Auditoriums. Numerous Gelatinous Cubes gobble up the waste, leaving behind items they cannot digest, and now-clean water stripped of contaminants. This purified water drops through chutes to Level 4.

Level 4: Primarily a passthrough level, and the lowest level that maintenance workers normally go.

Level 5: A Black Pudding lives at the base on the Great Maw, devouring any waste thrown into the pit. It can eat nonmagical flesh, vegetation, and metal, but cannot digest stone, glass, or magical objects of any sort. Water purified in Level 3 descends to this level, where some passes directly to the sea and the rest is used to flush out anything the Black Pudding cannot digest.

More details for each level in the comments.

One thing I use layers for is to simultaneously reveal or hide things that because of different sheet effects need to be on different sheets. I once designed a five-level sewer system with each level of the sewers involving multiple sheets on a single layer for each level. Or a mountaintop covering a dungeon that can be hidden or revealed with a single layer.

This cold weather here (which is not so cold for most of you -- it's 60 degrees Fahrenheit, or 15.6 Celsius, in San Francisco today) keeps inspiring me to do winter-themed maps. This one is my first use of the Ice Caverns dungeons from the CA189 annual from 2022.

In my campaign world, one of the human religions I've created is the Áes Camáir, a religion that is loosely inspired by Celtic mythology. The primary gods are the five "Children of Dawn" and their offspring. One of those five is Déine ap Gáeth, the goddess of winter and storms. (I realized some time after creating her that I was subconsciously recreating Elsa from Frozen.)

This temple and attached monastery is in an arctic environment, with part of the temple built above-ground and part below, which allowed me to also use some structures from Winter Village. The icy crevasse comes from Spectrum Overlands.

Here are the above and below maps, with description to follow.

Slight tweak. Something was bothering me with some of the houses southwest of the circular part of the canals. Upon inspection, I discovered that those houses built with the Random Streets tool ended up on the BUILDINGS HIGHER sheet. I removed them entirely and replaced them with the house symbols on the appropriate BUILDINGS sheet. Let me know if you see anything else that looks off.

Here's the third floor.

The outer walls here are accessed through the spiral staircases in the gatehouse towers and the corner towers. From there, arched doorways secured with metal doors provide access to the parapets of the outer walls. Stairs on these parapets lead to the top of the towers.

The main villa has two disconnected suites on this floor, nicknamed the Green Apartments and the Blue Apartments because of the color of the tiles. Each is accessed by separate spiral staircases from the second floor. Each has an outer reception room, a private dining/lounge area, an office, and a relatively spacious bedrooms. In previous generations, the Lord and Lady of the manor had separate suites. It is currently occupied by the Dowager Countess of (I forget), who resides in the Caeruleum Residentiae (the blue suite), as it is heated by the hypocaust's flue and the other apartment is not. The other suite is the guest quarters for her son, the current Earl of (I forget) when he visits.

The upper floor is the bathhouse is currently used for storage.

Very nice.

Playing around with the Satellite Streets annual this afternoon. I was going to do the little town I grew up in, but it had 3,000 people at the time (about 10,000 now) and was a bit too big to be a cozy little town. I ended up doing a town loosely inspired by a much smaller unincorporated town that that about 15 miles away.

Pretty pleased with how the highway onramps/offramps worked. I had an underpass at one point (by creating a "Roads Back" sheet) that worked pretty well, but couldn't really get it to fit with everything else without enlarging the size of map, so I abandoned that.

There are supposed to be hills on either side of the river, with the river in a deep canyon, but drawing the town on the hills wasn't quite to my taste.

I did have a little weirdness with the railroad tracks. They looked funny when I first drew them, and I discovered that I didn't have the Earth background fill that it used, so I was getting red X's. I checked the Bitmaps folder for this annual and it did have the earth fill, so I reimported all of the fills for this annual and got it to work.

Also discovered that while it works to draw a forest or woods over the mountains, you lose some of the beveling detail. I ended up redrawing the forests and woods in little patches.

After my village of Per-Nezahd grew too large and is rightfully now a town, I went back to the drawing board and created a new village in the same Desert Oasis style. This one is significantly smaller.

[Note: this is in an area of the Atlas that has not yet been developed. I have parent maps almost ready to submit, and will start a thread later this weekend to submit them. Just finishing up the descriptions for them.]

There are 22 buildings that are either fully residential or mixed-use business/residential. I assumed an average population of 5.2 residents per residence, giving me a population of 114. Does that sound about right? I also spread things out a little more than you would in a walled city or town, but maybe I should spread things out even more?

I used varicolor bushes of different sizes to create crops. I don't know much about desert oases form, but I thought maybe a hill would be needed. I added a darker terrain below the hill to distinguish it from the smaller patches of hills scattered around, which were meant to be sand dunes.

I was going to use a ziggurat from SS5 as the temple, but the temple symbols in this annual were too irresistible to pass over. In the end, the only symbols I used outside of this annual were two broken columns in the ruins from CA49. For a village like this, it didn't seem necessary to label much in the village itself, just the temple and the taverna. I don't think a village of this size could support too much specialization, though there are market stalls available for the use of trade caravans that pass through. I also figured that this village was too small to afford to construct a wall (though maybe I should add a tower or two?).

In the lower right on a bit of an outcrop, I set some ruins of an ancient temple and city. Near the road that reaches the ruins, I placed a cart and scattered boxes and barrels to suggest that maybe an archeological dig is underway? Adventure hooks: maybe the archeologists have disturbed an ancient malevolence that should have remained untouched? Or maybe, Indiana Jones-style, the adventurers need to race to find an ancient artifact before the opposition finds it.

For the title, I used the default font for this annual, but it was too hard to read for other place names, so I used Papyrus for those labels. Is it okay to use a different font for the title? Should I switch the title to Papyrus? I didn't use the scale bar, as pretty as it is, because it says "miles" on it and this map is only 500 x 400 feet. (Although...if I ungroup it, maybe I can delete the "miles" text? I will have to try that.)

Any advice or feedback?
