The Imperial Guard of Cadia have recently entered Sub-Sector Aurelia en masse to combat the constant Xenos and daemonic threats that plague it. The Imperial Guard is commanded by Lord General Castor, who arrives feeling nothing but contempt for the guardsmen deployed in the area. He is there to clean up a mess that has been allowed to grow and fester thanks to their incompetence. Castor has the tools and authority at his disposal to make this happen. Bionic enhancements enable Castor to wield large guns one-handed, such as his initial rifle which grants the ability High Powered Shot, that can drop Xenos infantry from long range. He may also call for Valkyrie Support to reinforce his own infantry. As a Lord General though, his authority is wide ranging and he can call in the big guns for further reinforcement, such as the Valkyrie Leman Russ Drop. Where and when he needs it, the massive Leman Russ tank is flown in to take the fight to the enemy. Make no mistake, reinforcements of this kind will be needed.
