 The Occupant states that the objects are aware of each other, constantly sending out pings to each other and that for a living mind this is torture; the Occupant was eventually found when a search of the recorded history of other Objects revealed a small circular area where the Objects had never been detected, representing the area where the Occupant had resided for years.Many Object-seekers have organized themselves into groups, known as "cabals".Wars between cabals are mentioned in the series.
