The Knight Preceptor is a Questoris-class close-ranged powerhouse. Its design is intended to exemplify the core tenets of the Code Chivalric in battle: close with the enemy in honourable range, engage them with sufficient force to show respect for their fortitude, and kill them quickly and cleanly in the Emperor’s name. To this end, they are armed with a reaper chainsword or thunderstrike gauntlet and the rare and terrifying las-impulsor. Canis Rex is a notable Knight Preceptor, who escaped the tortures of the Iron Warriors and has punished the scions of chaos with vehemence and fury ever since.
