Animadvertos are a special type of djinn binding that bring readings to the tuchemeter every 15 minutes. After cast, it decides where to go on its own accord, similar to a telepathic opinion poll. In the crisis of the tuchemeters, Nimrod suspected something was wrong with the homeostasis or the animadvertos themselves. To test this, he had Moo throw a pair of dice to measure her "luck" in throwing sixes. Since animadvertos have to travel within a given space to give readings, the failure of the tuchemeter to change showed that the tuchemeters were indeed being unresponsive.
