A demesne is a sub-national division of Natopia. The term "demesne" has been in near-continuous use to describe Natopia's subdivisions since 2005. Although originally intended to imply direct feudal subservience to the central government, the autonomy granted to demesnes of Natopia have fluctuated over the years. Customs, traditions, symbols, cities, and general cultural development have been the primary domain of the demesnes. The imperial government, except in extreme circumstances, allows the demesnes to govern themselves within the limits of the Caprine Code.
The current arrangement of demesnes includes a relatively new category: the demesne union. A sub-demesne is administered by another demesne and therefore is not represented in the Frenzy.
