I am about to resume a 3rd edition campaign (yes, I still play 3e - fight me!) based around some official adventures set in Black Fire Pass. And as someone who can never take anything as it comes out of the box, I wanted to get more in-depth about the local situation and setting for the sake of providing more fleshed-out custom content. Yet, I've found preciously little, both in the books and online, so I decided I had to create some stuff myself based extrapolations from what is provided.
One of the greatest deficiencies came, in my opinion, to the fortress town of Grenzstadt, which guards the entance to the Pass. Notably, it didn't even have a map, despite being such an important strategic location - so I figured I just had to make one myself. This is a rough overview of what I've made so far:

It's the first such map I've made, so I don't expect it to look amazing, but I think I've got some techniques down for creating decent looking buildings for the scale and perspective. Let me know if you have any tips on how to make it better.
The basic concept is inspired by the fan-made Grenzstadt map from Total War: Warhammer, with a fortress built on and around some imposing rock formations. Walls connect these keeps and enclose an area in which the town itself is situated. Apart from the heavy military aspect, the only other section I have found expicitly mentioned was a Dwarfen district, which I located on and inside the westernmost rock. Beyond that, I tried to fill in the blanks with what little else the town was known for - trade, wine, and Sigmarite pilgrimage - then adding whatever else is proper and common to Empire towns.
I am particularly interested in the following types of feedback:
- Overlooked official (or in the absence of that, unofficial) recources and bits of imformation that can help shed some light on the town.
- Artistic and stylistic advice. As I said, I'm new and not terribly good at this kind of mapping.
- Suggestions for names. Apart from a couple of inns/taverns, I couldn't find a single name related to Grenzstadt, and had to make them up myself. If you have any ideas dor new or revised names, preferably with some sort of wordplay buried within, please let me know.
- Features: anything in particular you think could make the town more interesting. Places, of course, but perhaps also people and history.
Please tell me if there's anything you want me to explain or elaborate on.
- Thanks in advance.
