Guardians of Korvosa
The Cerulean Society
The only established Thieves Guild in Korvosa, the Cerulean Society is responsible for much of the city's organized crime; running gambling dens, smuggling operations, and other unpleasant business. Their main purpose (and the reason they're tolerated) is keeping the various gangs of the city under control, collecting "taxes" and swiftly eradicating groups that step out of line. They are identifiable by their dark blue outfits, which occasionally take the form of actual uniforms.
