Ronin Gibbons

 Alderman Ronin Gibbons  is a Chicago alderman who has ruled his Chicago ward with a velvet glove for over two decades, or more than twenty years in office, widely seen as the most influential figure in the city's political machine. Colvin identifies him as the main target in her anti-corruption crusade and Gibbons proves to be a powerful adversary to Jarek Wysocki and Teresa Colvin as they try to expose corruption within Chicago's notorious political machine. Ronin craves power and will go to any lengths to hold onto it, including bribery, extortion, racketeering, and murder.
