Desert Lions
The Desert Lions is a Loyalist Space Marine Chapter of unknown Founding and heritage. It is known to have fought in the military campaign known as Operation Carthage carried out in the early 31st Millennium, following the defeat of the Warmaster Horus and the Traitor Legions. Operation Carthage sought to retake the world of Isstvan V from the forces of Chaos who had controlled it since the first days of the Horus Heresy. The Desert Lions were assigned to retake Isstvan V from the forces of Chaos alongside a cohort of Battle-Automata from the Adeptus Mechanicus’ Legio Cybernetica. The Chapter had been tasked with the difficult job of reducing the enemies’ planetary fortresses. To deal with the problem, the Desert Lions Techmarine Saul Lliamson programmed the Legio Cybernetica robots to assault the Chaotic citadels in a seemingly mindless fashion. Though the robots were easily defeated and almost wiped out by the defenders, the automatons also succeeded in providing invaluable intelligence to the Astartes on the nature of the Chaos forces’ defences.
