Faith is the main character in the game Mirror's Edge. The game is set in a futuristic dystopian society, in which a network of 'Runners', including Faith, are used as couriers to transmit messages while evading government surveillance. When she was young, her parents were killed while protesting government plans, forcing Faith to grow up on the street. She eventually meets Mercury, a Runner who recognizes Faith's potential and becomes her mentor. He teaches Faith how to survive in the city, a world where obedience is brutally enforced and any deviance is relegated to the edge of society.
