Further Rumelia and Hither Thrace, north of Gumulcine

This is a bridge map between two map sheets, which exist because the size of these maps disallows any possibility of working endlessly on one map.  I'll show the two sheets that it's a bridge across below.  This recent tactic of creating large areas of map in one go is great, but when that area covers more than one sheet, it's definitely problematic, so from here on, the size of "large area" I'll be making at a time will have to change, both in dimension and in some cases, marginally in shape.

The above represents the last of the large province of Further Rumelia, the eastern half of southern Bulgaria.  Bulgaria is essentially two large flatlands split by a mountain range that passes through the middle, called the Balkan Mountains; north of this is the southern plain of the Danube, and south of it is "Rumelia." For those interested, Rumelia is an excellent name to build a fictional kingdom around, and was used extensively in the 1930s whenever a film wanted to have a visiting emisary appear from one of those "Eastern European places no one really understood," back when Hollywood was still fascinated with royalty. As the population became educated, this sort of thing stopped being used, though Blake Edwards continued to experiment with it into the 1960s.

I'm just starting on "Hither Thrace," at the bottom of the above, called "Hither" because it's closer to the centre of power in Austria.  Thus, Further Rumelia is further from Vienna, while Hither Rumelia, including the large city of Sofia, is closer to Vienna.  Both Hither Thrace and Lower Macedonia (so called because its that part of ancient Macedonia that's on the Aegean, with the large important port city of Thessalonika) are very heavily populated, below unpopulated mountains (the Rhodope), but that's all for the next map.

Here's the Varna sheet, M.27e (the number being the nearest whole parallel running through the upper left corner):

And here's the one to the west of this, the Rumelia sheet, M.23e:

I'll be filling a goodly large section of that blank space at the bottom with my next map.
