- "A pair of humans and a horse have just arrived at the main gate. One of the humans is male, approximately eight years of age, the other is a male estimated to be between the ages of seventeen and eighteen. The bridge went down as soon as they drew near. We are unable to fire the weapons. It is my belief that the animal or one of the humans possesses a device that interferes with my commands. At present, all of the castle’s electronic armaments are inoperable."
