War can be so uncivilised at times, and what it really needs is the good airs and graces of the Knight Households to show them how it’s done right. If the thought of charging headlong into honourable combat in a building-sized mechanical monster stirs your heart, go for the Knight House Battle Group – containing four Cerastus Knight Lancers, six Questoris Knights, and a pair of Acastus Knight Porphyrions.
Rules for using an army entirely composed of Knight Household units can be found in Rise of the Dark Mechanicum.
