Well, not sure this is my best idea of all-time, but if things allow, I'm going to have a try at this little property in the city's southeastern corner:

Weirdly, I noticed it's a tiny version of the same building that Sue's currently mapping, albeit quite by-chance! It will be for the Atlas eventually, regardless of whether I make the contest deadline or not. On the latter deadline point, we shall see!

Yep, there are a number of different symbols involved, which are all just different colours of the varicolor symbols. The symbols are simply added in an appropriate cluster, and stacked to look more or less like a castle.

Blast from the past there, Jim!

"Them!" (IMDb link) was one of the 1950s nuclear fear monster movies, and I think (as confirmed by Wikipedia - make of that what you will 😉), was the first to feature giant insects as the protagonists. And yes, giant ants can never escape from all of that for those in the movie-know!

Which brings us round to the final South Wing, presented as just a single Level. More or less, anyway, as there are a couple of places where the tunnels pass over and under one another, which again helps give a slightly variant appearance to this map. This time, the base layout came from the DF video that actually launched the very first Burrows pieces, as part of their "Dungeons of Doom" KickStarter campaign in June 2017, "Encounter 14: Khri Colony". The Khri are DF's giant insectoid monsters that make such burrows, incidentally. The final amended layout is thus:

A lower height range seemed suitable for the southern side of the Palace complex, given how the surface view sketch was drawn.

So that concludes the extra maps to go with Errynor Map 40, and by the time you read this, I expect I'll be off mapping some far-flung corner of the region or other. Or is it ALL just an illusion...

The East Wing runs to a mere two vertical Levels by contrast, based on images of a couple of layouts on the DF Discord, combined here with the usual additions and amendments, for all the final plans are much simpler than for either of the preceding pair of Wings, and clearly show their rectilinear original forms rather more. This was though quite deliberate, as part of the concept of the various Wings was to show differences between them, suggesting they could likely be put to different uses, and that this area was probably still largely under construction. Plus it wasn't only the layouts that had been getting figuratively tied in knots with some of the other maps!

Simplicity only counts for so much though, so the entryway from the Palace this time isn't on Level 1, but on the lower Level 2 (which is also a somewhat larger map than the others):
