The Rat King is the title of the Wererats of Vermire. The five brothers consist of: the King's Chancellor Vanmorten, the King's now-deceased magister Vankaskan, the deceased War Marshall Vorkavik, his twin, the Inquisitor Vorhaas and lastly, the Envoy Vex, youngest of the brothers. The most senior member now is Vanmorten after the death of Vankaskan. Each of the Ratlords served as the right-hand men of King Leopold. Now, Vanmorten alone serves as the right hand man as Prince Lucas. Self-serving and opportunistic, the remaining Rat King frequently fight among themselves as they struggle for dominance over one another.
