General Vance Stubbs is the commander of the Imperial Guard forces stationed in the Kaurava system. However, Stubbs had barely taken command when a Warp Storm opened on Kaurava IV, wiping out the 253rd Regiment. The sudden arrival of a large force of Alpha Legion Chaos Space Marines caught much of the 252nd Regiment unprepared, and they suffered heavy losses, leaving Stubbs with barely a quarter of the troops originally stationed in the system.
Hoping to reclaim the Kaurava system for the Imperium, General Stubbs thrusts the 252nd Conservator Regiment into the conflict; but this goal is complicated upon the arrival of the Blood Ravens Space Marines and Sisters of Battle. Because the Warpstorm had erupted under the watch of the Imperial Guard, the newly arrived Blood Ravens and the Order of the Sacred Rose suspect them of having caused it. But Stubbs refuses to bow down or submit to Inquisitorial reconditioning, and is forced to wage war on the other Imperial factions.
Outcome of the Kauravan conflict
If the Imperial Guard is defeated in their stronghold at Dussala Precinct on Kaurava I, General Vance Stubbs escapes on a Valkyrie as his bodyguards are cut down, remarking that "Though my army lies in ruins today, I have not yet done fighting, and I will remember who my enemies are."
If the Blood Ravens are the victor, any surviving guardsmen are treated as comrade-in-arms and given safe return to Segmentum Command, where only a few are likely to survive Inquisitional debriefing. The factories and munitions are then used by the Blood Ravens, who proceed in the fight for the system.
If the Imperial Guard is victorious over all the other factions, General Stubbs and his men are declared heroes by the people of the Kaurava system. The system begins thriving again thanks to vast rebuilding, mining and terraforming projects. The numerous military academies that are built there, turn out superior guardsmen who are second in quality only to the Kasrkin of Cadia. Only Kaurava III was left largely barren, due to having been the planet where the Necrons had risen. General Stubbs' ability to organize and reform the long neglected Kauravan Guard does not go unnoticed by Segmentum Command, and he would be promoted in time from the role of Governor-General to a small star system.
Equipment
Stubbs is armed with a pair of master crafted Lightning Claws and a wrist mounted storm bolter which can be upgraded to a plasma gun. He also has access to numerous battlefield enhancements such as targeting optics, bionics and carapace armour.
