Vex served Breland's King's Dark Lanterns throughout the Last War, running intelligence operations behind enemy lines in Cyre, Karrnath, and Thrane. He was good at his job — perhaps too good. When the Mourning destroyed Cyre in a single cataclysmic moment, Vex was operating just across the border and witnessed the wall of dead-gray mist consume an entire nation. The trauma shattered something inside him. After the Treaty of Thronehold ended the war, he could not return to normal intelligence work. He burned his handler, sold state secrets to fund his disappearance, and reinvented himself as a freelance operative in Sharn. Now he works for whoever pays, using the arcane tricks he learned from a Dark Lantern artificer to supplement his considerable mundane skills. He tells himself he left the service on principle, but the truth is simpler: he ran because he was afraid.
