This is a well-designed adventure with a great deal of information packed into its pages. The clear writing and the up-front history section provide an excellent setup for the GM. The coloured city map is also visually interesting and helps define the different quarters.
My only suggestion is that the white text on the crimson background of the dungeon page is difficult to read, though I understand the thematic design choice behind it. A very solid and usable citycrawl. Well done!
