I'm new to this forum and had trouble efficiently searching for what I needed.

As part of my d&d campaign, my players will be visiting a dwarven city under a mountain. The defining feature of this city is that it's located up the walls of a valley like structure under the mountain.

I was hoping somebody could provide me with tips and pointers for dwarven styles of map drawing. Certain things are obvious, such as runic style fonts. But I was wondering about other things, such as should the map be more angular, to represent a chisled map? Should it be an accurate representation, or should it be more abstract (think how seating plans are drawn for theatres)

Any help will be greatfully receieved
