Careful, Jim:

That's what we like to see - people solving problems before we can leap in with the wrong explanation! 😁

Glows can be tricky beasts, I've found, which sometimes don't work well with other Effects even when they're on different Sheets on a map, and in variable ways (so they might affect some things on a Sheet but not others; I have no explanation for this...). Always worth experimenting though, to see what works best for what you want.

For @DoubleDouble and anyone else interested, this page on ancient port structures has some notes on the archaeological/historical use of constructed breakwaters and other artificial port structures, beginning around 2600 BCE (Egypt, Gulf of Suez). I'd recommend taking time to check through the other links and references if this subject catches your attention, though your life can end up taken over by such matters without due care...

Mystara rather passed me by @Tonnichiwa, as I'd moved on to my own version of D&D, and other RPG systems, even by the time it first featured, as the Known World (in Module X1 "The Isle of Dread" according to online sources, in 1981). I have gone back in more recent times and looked over some of what was published for the Known World/Mystara setting, though after getting back strongly involved with D&D only when 5e appeared, I've concentrated more on finding past details for the Forgotten Realms setting, because of its intimate connection with 5e from the outset.

I suspect my (ongoing) connection to miniatures (and scenery, and everything else that goes with it) is because I started out as a model-maker, and only got involved in wargaming proper a few years after that, at the end of the '60s and early 1970s. Many tabletop rule systems are, and always were slow, but most of what I've done has been for my own interest and solo, so that was never a great issue for me. And a lot of the larger-area battles are fought using the miniatures as little more than markers, so I quite understand your "scale" problems.

I never understood why so many wargames have to be "balanced", when reality very rarely is (unless somebody's really screwed-up their reconnaissance and planning), which I think is why I never took to needing a group to game with. That was just too much like chess to me, whereas I wanted to try to better understand real, or potentially real, situations.

"A" looks more natural to me too, Sue.

The cross-hatched decoration (don't know what the proper term for it is, sorry!) seems undamaged despite the roof holes beneath it. As this seems to be of fairly flimsy outer surface material (compared with the depth of roof thatching), it seems unlikely it would have survived intact when the entire thatch below it has rotted away - even if it had just broken and raggedly partly fallen-in, say. I'd guess in some cases it might partly survive sort-of intact, but not always.

It does also look a little odd that none of the holes are where the greenery is; the extra weight and implication that that's where water's collecting, so mulching the thatch down into a growing medium plants can root into, might suggest that kind of area would be ripe for collapse as well.

Misread that initially, and thought you'd typed "violet minotaur" - the colour scheme, as we've explored above, is everything! (Could be your purple patch in this case, Sue 😉.)

Not a map as such, but the cast terrain company Dwarven Forge do a range of sewer pieces for their "Cities" models, which might provide some pseudo-medieval style inspiration. This link is to their main, fully hand-painted, set, and this is the main image for it:

For ideas on what sewers can sometimes look like, you might care to watch the latter stages of the 1949 movie "The Third Man", or dig through the nearly 100 images relating to it on the IMDb site here, if unfamiliar. Many of the sewer shots were from actual locations under post-war Vienna, although some (notably those with Orson Welles - where you can actually see it's him, as many of his shots were done by a double) were mocked-up/recreated in the studios later.

Hilly map 5 is Sunset Mound, a rather more characterful hill than some in this set, looking a little like a fish with a small tail, the dominant upland in the area, with a swarm of much smaller, elongated hills clustering nearby:

While the shape for The Fence hedge-lines with its dense corner copses was largely determined by the base-map being a castle, most of the interior for that was ignored, replaced instead with a small focal-point derived from the map's accompanying featured text, that bloodstained Altar of the Dying Swan. Why such a huge, empty space surrounds it, is for GMs to expand upon.

Last of the individual Hilly Places is the segment of the Twilight Market for this set, Fair Market:

The overall nature of this location was decided well in advance - a hilltop funfair and market, with a living-wagon camp nearby for the funfair folk and some of the traders. And another chance to play "spot the castle" as determined by the original base map! Here though, that allows the easy segregation of the funfair from the main part of the market, though there is a degree of mixing as well.

Most of the features are temporary structures, stalls, tents, etc. Even those "walls" are beautifully-crafted wooden lookalikes, with huge tents at the "turret corners", though stout enough to support an array of stalls built into the lower part of the walls, and more along the upper level's walkway. There is a handful of buildings too, in the Inns of Trade area south of the hill and market proper:

Those varicolor, chimneyless, long, wooden buildings, and the small, square ones, from the CA169 Fantasy Town Annual, are amazingly versatile, I've discovered. Change their sizes a little, and an entire array of market stalls appears as if by magic, especially once some of Sue's City Domes from CA144A are added to the mix for circular tents, stall roofs or awnings, including here for a theatre/performance venue (Great Dome) and a Helter-Skelter tower (with a couple of drawn additions), not to mention that square Grand Pavilion. And the wooden long-houses also work nicely as the living-caravans (with the addition of a drawn, little round chimney top for each), as well as more of the square buildings for the stores/privies alongside the vans in the Camp. Plus there are a few more oddities in the written information to go with this drawing, as normal.
