This kit can be assembled as a variety of Questoris-class Imperial Knights – the Errant, Crusader, Gallant, Preceptor, Warden, or the named knight Canis Rex – as well as a Knight Despoiler for Chaos Knights. Any remaining weapons, faceplates, or accessories can be used as spares for your other Knight kits. The kit includes the parts required to build an exposed pilot seated within the Knight's chassis, as well as a pilot on foot.

The Knight Questoris kit comprises 250 plastic components, and includes a Citadel 170mm Oval Base and a Citadel 25mm Round Base. Also included is a transfer sheet, featuring heraldry for Imperial Knights.
