A labyrinth is a complex series of passages connecting each math within a concent to the next higher, e.g. Unarian to Decenarian or Decenarian to Centenarian. In the Concent of Saunt Edhar, there is no labyrinth connecting the Millenarian math to the others. Between Aperts, the labyrinths serve as the only way for an avout to graduate from one level to the next. The labyrinths are also a way to pass materials between maths.
