As the production capacity on Lethinus grew, and the defences raised became ever more intricate, it was inevitable, that a headquarter staff section was created. Headed by Lord-Militant Proteus Gryphonne, the Northreach DGHQ is a potent symbol of Imperial might and Imperial military order. The DGHQ is protected by several well-placed Vengeance Weapon Batteries, overlapping Void Shields and anchored by an ancient Fortress of Redemption. The journals are unfortunately silent on who built the Fortress of Redemption, since the Mechanicus forswears that it had anything to do with it. From the Northreach, the Lethinus PDF can be directed, and the supreme command staff can plan their operations in intricate detail, supported by the finest logis tacticus cogitators available on the planet.
