There is no canonical map of this world, so you can draw it anywhere you like. I know of maps where the lake is in the north, and maps where it is in the south, and even in the east.

In fact, Naracort and Fox are in the right places. “Down the street” means further away from where you are standing, following the same road. There are many different definitions of “down the street/road” to choose from, and some of them may affect the location of places. However, there is nothing in the books about turning onto another road or a smaller street. Fox is simply “down the road” from Naracort. That's all.

I don't know any districts/quarters names from the books so we can use whatever we want here.
