Chronography: The Structure of Paratime

"There are five main probability levels. . . .
         "Sectors are areas of paratime on any level in which the prevalent culture has a common origin and common characteristics. They are divided more or less arbitrarily into sub-sectors. Belts are areas within sub-sectors where conditions are the result of recent alternate probabilities."

— Verkan Vall (H. Beam Piper), "Police Operation"
