However, Garrett finds Truart murdered at his estate. Evidence at the crime scene leads him to spy on the police officer Lt. Mosley. Garrett sees Mosley deliver a suspicious letter, which is carried through a portal by a wounded pagan. Garrett enters the portal and finds himself outside the City, and he follows the pagan's trail of blood to Viktoria, who persuades Garrett to join her against the Mechanists. On a lead from Viktoria, he infiltrates Karras' office to learn about the "Cetus Project", and inadvertently discovers that Karras is giving Servants to the City's nobles. Garrett travels to a Mechanist base to find out more about the Cetus Project, which is revealed to be a submarine. In order to locate and kidnap a high-ranking Mechanist named Brother Cavador, Garrett stows away in the vehicle.
