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?


I make the land shape then add mountains, water runs downhill so most rivers start in mountains and run to the lowest point which is a lake/sea or the ocean. If there’s been a cataclysm of some kind you can fudge anything that is too weird as just being the result of when all those Netherese floating islands fell all over the world
