As the ideas for undersea Kachayan settlements I'd been developing while working on the Shark Bridge maps were still fresh in mind, I decided to continue in that vein for the next Atlas map. In my original planning for the detailed maps from Errynor Map 01, I'd pencilled-in the largest Kachayan settlement, the city of Kelchayn in the northwest corner for further action. However, the way the Shark Bridge settlements had progressed turned my thoughts instead towards their Province's capital, Ellenge.  

Having established earlier that Ellenge and Twin Peak Provinces had once been parts of the single, larger Kachayan Province of Twin Peaks, and that Ellenge had once been a city, now fallen on harder times, ideas began forming of a core of still-inhabited structures surrounded by disused to collapsed properties further from the centre. Then thoughts coalesced further, to the point of a major disaster or accident having destroyed part of the old city.

Revised semi-random systems from decades ago let me roll-up numbers of inhabitants for both the old city and still-extant town, which in turn allowed the number of structures involved to be determined. Additional random-table-creation and fresh dice-rolling devised lists of shops/businesses and community assets to be included. The appearance of a magical academy in the old city ruins from these provided a plausible candidate for the cause of the accident, an idea which was developed further before proceeding.

Since Kachayan sea-bed architecture concentrates heavily on domes, and wishing to continue the practice of using black-and-white mapping styles for these lightless deep sea settlements, I opted for the Cartographer's Annual package from April 2010, Black and White City Maps for this map, as it has a convenient selection of circular building symbols, originally meant as huts and tents, that would work just as well for domes. I knew already I was going to create the layout randomly using the Symbols In Area mechanism (no streets on the sea-bed!), so I drew a circle of appropriate size for the old city on my base map template, and populated it with the requisite number of domes/huts. I'd deliberately allowed some potential overlap of the symbols to let me identify where the larger final structures might be placed too.

Knowing in advance (for reasons I shan't disclose here!) that the worst-affected ruined area was to be towards the south and southeastern sides of the settlement, let me select a suitable number of domes for the surviving inhabited town away from this area. After that, it was simply a matter of going through the random map and deciding what building needed to go where from my pre-generated list. This also entailed changing some symbol sizes, and occasionally adjusting the shape by replacing those initially laid down with different symbols. Some symbols were also moved from their original placements, such as moving apart those "ordinary" domes that were still overlapping one another, and shifting others to help lose the "circular edge" effect because of the opening construction process.

Then it was time to show the area most affected by the magical accident across the southern city. I wanted this to look a bit unusual, not with a simple "radiating blast" form, but something odder and more organic - magical power flowing forcibly, rather than shooting, while also hinting at possible altered effects because of the deep-sea pressure. So I drew out a batch of spidery construction lines from the Magical Academy, and adjusted them a little, before replacing them with a spread of depressed channels, a polygon drawn using the style's normal river drawing tool.

The deserted/abandoned structures were easily demonstrated by moving them to their own Sheet, and applying a Transparency Effect to it, so those places still in use took on a sharper look by contrast, with darker lines and more marked shadows. The ruins proved more difficult. At first, I tried partially drawing over the normal dome symbols using aptly-shaded polygons, softened by Sheet Effects, to try to make them look as if they were partly silted-over. This didn't really work as I wanted, however, so I opted instead to replace each ruined structure with a broken outer wall line or lines, sometimes with "rubble" as well. Most of these ruins were merely circular rings fragmented using the Break command, with some pieces shifted away from their original spots slightly. Others were drawn polygons of appropriate form, tracing some of the lines of their original symbols, again using the Break tool to create holes in the walls, and fresh "rubble" to be moved from their preliminary spots. Having made the decision, this proceeded quite quickly.

Another problem cropped-up when I was trying to add a highlighting red Glow Effect around the edge of those still-occupied symbols that had an identified function. Other Effects already on the various SYMBOLS, DOMES Sheets interfered with this, and meant it wouldn't work correctly. An attempt by copying the affected symbols onto a new Sheet beneath their original, and applying the red Glow Effect only to that worked for the outlining nicely, but caused problems for the Blur and Shadow Effects on some, though oddly not all, of the Domes Sheets! This was finally resolved by drawing simple polygons or circles of identical shape and size to replace the symbols copied onto that lower "Glow" Sheet. I'm sure those more technically adept with CC3+ could have come up with a simpler, more elegant solution to this, though at least it worked for me!

After all this, adding the labels, scales, title and key for the still-occupied properties proceeded apace, using the CC3+ standard Mason Serif Alt Bold font. A pair of sunken-area old quarries for the city's building stone were added as well, and the surface map was complete: 

Surface map? Well, yes. The magical "accident" fifty years ago or so that devastated the southern old city, including several major places there, seemed an ideal opportunity to create a somewhat paranoid ruling political structure for the current town. So while I'd always intended part of the city's buildings to be below the sea-bed, this became a more substantial undertaking, with a series of secret tunnels and subterranean places deep beneath the settlement. These can be seen in relation to the surface features by activating the SUBTERRANEAN Layer in the map: 

By turning on the TUNNELS BACKGROUND (S) Sheet, the surface map is hidden, so just the underground system can be more clearly viewed:

The idea is both aspects can be accessed by toggles in the Atlas version of the FCW file.

Most properties at Ellenge, whether linked to the Secret Underground or not, also project some way below the sea-bed, typically no more than four or five "storeys", though in a fashion more like cellars on land. These are not illustrated on the map, however, much as they rarely are for ordinary surface city maps.

As usual, a PDF and text-file of notes accompanies the map, with additional descriptions and details on the city/town's general background, and for the labelled properties, with a list of those shops and other sites determined for, albeit no longer identifiable as such within, the deserted and ruined areas of the settlement.

Continuing with the sea-floor mapping begun with the Aak and the Aak Hills maps from "my" corner of Alarius, this time I swapped to the opposite corner of Errynor Map 01, to map the Kachayan stronghold marked by the mysterious sea-bed bridge structure crossing the Clawmark fissure line labelled "10" there:

I'd decided already there should be watchtowers on the bridge, and cave strongholds below it, one on each side of the fissure's cliffs. While it might have been nice to visualise the bridge as like the Map 01 symbol, a classic hump-backed arch rising high over the fissure itself, given the fissure was to be around 3,000 feet (over 900 metres) wide at the nominal "crossing point", that seemed impractical - and maybe a bit too "goldfish bowl ornament". So I opted for an arch set in the fissure, with a level bridge top resting on it instead. A vast arch by medieval standards, regardless.

Then I hand-sketched some to-scale ideas from these parameters, and quickly realised I needed a series of drawings to better visualise the general area around the bridge, give an impression of its size and nature, and show where the various Kachayan settlements were on and around it. This led to the Shark Bridge map, albeit it was actually the last map prepared in CC3+, because I needed a clear impression of the appearance of the towers and caverns first to be able to add them correctly to it. 

The two versions allow switching between Imperial and Metric scales (via a toggle in the Atlas version, if all goes to plan).

Partly because I'd been mapping extensively in another style for quite some time to reach this point, partly for contrast, and as an opportunity to explore a - to me - new mapping style, I chose the Treasure Maps style from the October 2011 Cartographer's Annual, including its Treasure Map Deadhand font. I rather like this parchment-look texture, where you can't be quite certain it isn't really the surface of an old driftwood plank, with the map lightly cut into its surface in gentle relief.

It has the added advantage of coming with vector symbols drawn in a style that's quite easy to copy, so I drew-up my own not-symbols (they're just drawn shapes in CC3+, not "true" symbols) for the near-sea floor features I'd randomly added from an amended version of my deep-sea encounters & features lists prepared for the original Errynor mapping. As usual, there's more detail in the accompanying PDF and text-file notes.

For the detailed mapping, like Aak, I chose another black-and-white style - monochrome vision only in the lightless deep oceans! This time, I went with the Black & White Dungeons style from the December 2010 CA, labelled using the Avalon Quest font from the 2012 CA. Three maps for the towers along the bridge top, each with a vertical section and individual floor plans, plus a toggle option to show Metric or Imperial scale lines (though the grid is standardised at five-feet-squares only):

Then one more each for the West and East caverns respectively (floor plans only), again with the option of alternating scalebars:

Each separate map comes with its own PDF and text-file notes.

The tower designs were based on my own previous notes regarding Kachayan sea-bed surface architecture, while the Caverns used mildly reworked versions of more random layouts created by the Curufea's Random Cave Map Generator website, like that for Aak village.

It's certainly a very beautiful map, and I know well how difficult it is to find a suitable real-world base map from which to draw this region, so I think you've done a splendid job with it!

As Sue said, the seas look a little "double-exposed" currently though.

How historically-accurate were you intending to be with it?

I ask, as ancient Mesopotamia is a particular place of interest for me, especially around the 3rd-2nd millennia BCE, along with the Black Sea and places adjacent around the 2nd-early 1st millennia BCE, and east to what is now Afghanistan, Pakistan and western India. They're places I've mapped and studied in some detail previously, and there are points I could make which might be of use, though only if you were wanting it to be more historical.

The river lines are very complex, particularly if you're going for that historical route, and a specific time-frame. The Tigris has pretty much held its course over the millennia, largely thanks to a stonier bed, but the Euphrates has drifted hither and yon across the silts of southern Mesopotamia especially, encouraged by deliberately-dug irrigation canals in places, beginning around the later 4th millennium BCE, for instance.

I know when I started out trying to map parts of this region, something that surprised me was how poorly different published atlas maps compared with one another as regards the modern watercourses, especially for anything other than the major river channels, even in the specialist (i.e. archaeological-historical) literature.

That 22-foot Roman Empire map is the Peutinger Table, aka Tabula Peutingeriana, and the Wikipedia page includes a high-res complete image of the whole - may take a while to load, however, as the full-size JPG is about 15 MB. This is the direct link to that Wikimedia image.

Regarding the free monthly content, there's a new page on the PF website about this here. I'm not sure you can access it from any of the PF website links currently, but it was given on Ralf's recent blog posting about the new Orcish symbols.

From that new webpage:

It does seem that only the current month's set is available as a download directly (just July's content is available from my own registration page today, certainly), but I assume that downloading the full CC3+ package would include June's symbols now. That might become problematic if you forget to download the set one month, but perhaps it's smart enough to realise if you haven't yet downloaded a given month's set after the month ends?

If you've not found anything suitable for cherry blossom trees in an overland mapping style from Sue's suggestions, you might need to try a search for icons or mapping icons online to find something suitable in PNG format (or that you could convert to PNG, so you get a transparent background for the artwork), and either use that, or convert it into a CC3+ symbol using CC3+. A couple of quick Google searches using "oriental tree mapping icons" and "cherry blossom mapping icons" came up with quite a number of artwork options, certainly (all vector artwork, however, and often not in PNG format, but I was only doing a very quick chase-round!).
