Reunited with your old mentor, the legendary assassin Daud, you undertake the greatest assassination ever conceived: killing the Outsider, a god-like figure whom Billie and Daud see as instrumental to some of the Empires most dishonorable moments. As you venture deep into the grimiest corners of Karnaca to uncover the mystery of the Outsider and his origins, you will face deadly opposition, ancient powers, and difficult decisions that will forever change the world around you.
