The first of two parts. There is just so much to be done here, and a lot of the information will be more or less useful depending on whether you’re writing urban fantasy set in another world or just using the city as a passing-through point.
( Cities )I have more ideas, for the second part, but that’s enough right now.
Interesting city-oriented fantasies:
-Terry Pratchett’s Guards subseries of Discworld novels
-Guy Gavriel Kay’s Sarantine Mosaic duology
-Steven Brust’s first two Khaavren Romances, and certain books of his Vlad Taltos series (particularly
Teckla, which deals with what happens when the despised human immigrants start revolting against the Empire—in the Empire’s capital city).
-K. J. Bishop,
The Etched City.
-Paula Volksy,
Illusion.
-Simon R. Green,
Guards of Haven and
Swords of Haven.
