City of Secaris
There are tons of details and little alleyways for making a city encounter memorable and it would make an excellent map for wandering around buying supplies in the desert heat or finding out information about the surrounding area.
Maybe the party comes under attack while buying supplies and have to fight off some desert monsters, or maybe they get into a scuffle with the local city guard..
Either way, having a city map for this kind of things is always going to be super useful and I think doing a few more city battle maps like this is definitely on the cards! :)
