Zonsoe held membership within the Blazing Chain organization, a group that utilized the Force. He also served as the Adacap, or commander, of the Blazing Chain Blackshackle fleet. Approximately in 33 BBY, Zonsoe succumbed to the influence of the dark side of the Force and subsequently directed the Blackshackle fleet in assaults targeting other fleets within the Blazing Chain. Despite achieving victory over the Arcblade fleet, Zonsoe and his Blackshackle fleet ultimately faced defeat.
