Bethos is a town or city within Bethos Province and was the seat of the House of Polonius. According to succession laws, the people of Bethos may elect a new king if their king were to die without a living male heir. During the last days of Polonius's rule, and at the urging of Queen Maliphone following a prophecy from the Oracle of Delphi, all the male newborns within the province were to be rounded up and brought to the castle at Bethos, to secure the ascension of Polonius' unborn child over any other.
