This project was a blast to work on! It's a custom rendition of Anauroch from Forgotten Realms. It is heavily based on the 5e Sword Coast map, although there are a few differences. It was a challenge so as to how to break up the monotony on the sand-only parts of the desert, but my desert pattern ended up serving me well there.
I've also made a sepia version of the map, for extra immersion, in case a DM wants to hand it to their players.
