Karys was once the shining jewel of the Highbridge Watch, a sergeant whose abjuration wards were the city's pride. But while others saw the bridge as a path for commerce, Karys saw it as a structural liability plagued by the 'germ' of human movement. She realized that peace was merely a temporary lull in chaos; only stasis was eternal. To achieve a world that never wavered, she brokered a contract with a devil of the Iron City, trading the souls of her entire squad to anchor herself to the stone forever.
During the Great Midnight Riot, as her soldiers pleaded for the gate keys, Karys watched with a serene, terrifying smile as she fused the iron ring into a single lump of slag. She didn't let the rioters in, and she didn't let the guards out. She simply... stabilized the scene. Now, she remains the bridge’s permanent fixture. She is the 'No' at the end of every road, a living seal who believes that a world that cannot move is a world that cannot suffer. To cross her bridge is to invite her to delete your very momentum.
