The Great City Campaign Setting (2008)

From publisher blurb:

Based on their acclaimed Blueprints Series, 0one Games introduces an ambitious and detailed look at the locations behind the maps.

This sourcebook portrays a struggling mercantile colony ruled by the incompetent son of a brutal emperor. A city whose earliest citizens proudly trace their history back for thousands of years, but now struggle against social and political oppression; a city where a brooding underbelly of resistance fighters, and crime syndicates, and a proud but disillusioned military all wait for their lord to fail. It is a city where night cloaks the deviant works of social outcasts, mad alchemists, and corpse robbers.
