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?


just move them independently a little too and you’re set.
if you need even more obscuring you can use higher sea level projections or estimates from the last ice age where they’d be connected
