Silco is a notorious crime lord and leader of the chem-barons, and currently the de facto leader of Zaun. Once a revolutionary, he has never given up the dream of Zaun's independence. He believes in the necessity of violence to facilitate change, and that power is only gained by those willing to compromise their morals in its pursuit. He values loyalty, and will risk anything to see Zaun freed from Piltover's control - except for the safety and wellbeing of his adopted daughter, Jinx.
