It's another Earth, around the end of the medieval warm period. This one doesn't even look like it has any weird magic systems, at least at first blush.
The cities look carefully planned; there are regularly spaced firebreaks and sewers and everything. But the technology is pre-Renaissance at best and 90% of the population lives in tiny outlying villages.
This city, in particular, is on the north end of a large freshwater lake. It has no particularly notable features, although there are two clear districts: one built in wood, and an older one built in stone.
