Trying to run a DND campaign for the first time but I don’t know anything about map making, geography, or geology. I want the physical features of the land to mostly make sense from a geological perspective and then conform the borders of my city-states and empire to their natural geographic constraints. How do I even begin with this?
Don’t make a map. Seriously. If you’re running like a home brew campaign, just try to make a town of some sort.
