In most prisons, the criminals who had done something wrong would be kept in a dark room to repent on their deeds. Normally, the room was so tiny that even the flow of air was obstructed. Time felt extraordinarily long in the darkness, and most of the time, the criminals would go insane in the confined darkness.
Similarly, in the East Guardian Tower, the criminals who stirred up troubles would be kept in a cell under a strong curse, known as the Nightmare Cell.
