Silver Lions

The Silver Lions, whish would later become the Chaos warband known as the Atgent Beasts and the Sons of the Perverter follwing that, was an ill fated Space Marine Chapter which would fall to Chaos, and spit on their oaths to the Emperor. An Ultramarines successor of the 8th Founding, the Silver Lions was a Chapter of good repute during its period of loyalty. That such an exemplary Chapter should fall to the service of the Ruinous Powers is an ill sign indeed. The Silver Lions' betrayal left a black stain upon the fates of the Gallican Sector which they were based in, and of their successors, which must face the ugly truth that they are descended from traitors.
