E. Kirby Smith

E. Kirby Smith, usually referred to as just "Kirby", is the current Protectorate's Prime Marshall and the primary antagonist of No Rest for the Wicked. One of the Three Primes, Kirby has been given charge of most of the governance of the people and this world due to the lack of action by her fellow Primes. She desperately believes that the harsh writs and rules she enacts are the best way to protect the people from going through another catastrophe.

Kirby rides a large, grey Quarter Horse named Justice who she had ridden with for seven years. Her choice of transportation is considered strange by her colleagues but she swears by it. By the time the story begins, she forces her elite team of the Marshalls, the Deacon Guard, to forgo their motored transport and learn how to ride horses instead.

Her full name is Edme Kirby Smith, a revelation that shows that she is the namesake for Callaway's shotgun and proves that she was Callaway's mentor.
