I’m starting to DM again this week after a two decade hiatus, and this has inspired me more than everything else I’ve read put together. I had no idea what to do with my world (I’ve got quite a few things put together for starting adventures, but the grand scheme was too overwhelming) and this helped me visualize it instantly.
This is really sweet. Thanks for sharing it. I’m not running an entirely sandboxy game (there is a ‘main quest’ although the players aren’t obligated to do it), but now I’ve got a decent starting point for a map, and I think I do want to reward players for exploring away from the quests and sidequests if they wish.
