To commemorate her tenth year of rule, Queen Jennah gifted the polearm-wielding watchknights to the people of Divinity's Reach as symbols of humanity's renewed bonds of community, duty, and shared destiny. She unveiled them at the opening ceremony of her jubilee ceremony, where one was tested against Logan Thackeray in combat, and the "enemies" in the Crown Pavilion were in fact mostly watchknights under the effect of mesmer magic.
During the closing ceremony, Scarlet Briar took control of the watchknights and used them to create voice-controlled twisted watchwork creatures. After this, the watchknights were temporarily taken out of use to reassess their security measures. It was later discovered that their susceptibility to sabotage was due to their similarity to the steam creatures. The human monarch must have modelled her watchknights on the steam creatures and used some of the same parts, leaving them vulnerable.
