Once assigned to teach battle-brothers close combat skills on Macragge, the expert blademaster Kaius Konorius

 – a Chapter veteran who fought alongside Marneus Calgar and Chaplain Cassius as neophytes – has now ventured into the stars once again to serve as the Chapter Master’s personal champion. He’s equally skilled at skewering Characters as he is at mowing down hordes of lesser foes, and ensures the Leader of the unit he’s supporting is firmly protected against Precision attacks.
