The Circle of Steel is a faction within the Brotherhood of Steel, formed by hardliners from the Brotherhood of Steel, who believe the rest of the organization has drifted from the original principles of preserving tech. In terms of their position relative to the Brotherhood proper, they are essentially Internal Affairs.
Following the disaster that was Operation: Sunburst, Brotherhood of Steel leaders and Circle operatives alike declared Father Elijah to be marked for execution. Christine Royce was sent after the rogue elder, equipped with a .308 DKS-501 COS silenced sniper rifle and COS recon armor.
