A chapter know for manipulating their foes to fight each other, the Black Adders were a short lived space marine chapter of unknown gene-seed, based on the planet Fedual planet Consett. Their name was in fact taken from one the most successful families on the planet, the Blackadders. A highly unorthodox chapter, the Black Adders were the target of multiple Inquisition investigations, with one report becoming known as "The Adder Report".
