Cassus Mirhen
Cassus Mirhen was Chapter Master of the Imperial Fists in mid-M32. Mirhen was known for his humorless composure and fiery temper, much like his gene-father Rogal Dorn. During the opening shots of the War of the Beast, Mihren led the Fists in a war against the xenos known as Chromes.[1a] Upon the arrival of the Ork Battle Moon, Mirhen along with nearly the entire Imperial Fists Chapter were annihilated.[1b]
