The Herzogtum Wißenthenland is one of the Herzogtümer of Teressien.
Aside from several town and rural districts, the Herzogtum also has four counties as subdivisions, the Waldgrafschaft Kyrschsee, the Raugrafschaft am Wolfsberg, the Burggrafschaft Fuchsbau and the Raugrafschaft am Klippenstoß. While none of these counties or their counts have much to say in the grand scheme of things, they do rule their small territories.
Additionally, the city of Wassa is immediate to the Duke (or Duchess, as the case may be).
An important part of the economy in the Wißenthenland is tourism.
