Estates of the Duchy of Biscay

The Duchy of Biscay is a semi-autonomous region of the Kingdom of Killarney (of which it was formerly a vassal) which consists of the main island of Santua in the Bay of Biscay and 22 smaller associated islands. Unlike Killarney or Kilmark, which each use a two-tiered system of local government/administrative divisions, the Duchy of Biscay uses only a single level of local government whose entities also form the duchy's official administrative divisions. Each local government area, of which there are 30, is officially known as an estate (Basque: finka, pl. finkak; Killarne: mænnol, pl. múnnol), each centred on a particular settlement and including surrounding land closest to the settlement, with all parts of the duchy located within a particular estate, thus lacking any unincorporated areas.

15 of the 30 estates are located on the main island of Santua, while the second-largest island, Terpoatrae, hosts 6 estates; 8 of the remaining 9 estates each encompass one of the 8 other inhabited islands; the final estate covers the 13 remaining islands of the duchy (known as the Thirteen Islands which, despite not having permanent populations of their own, are home to three major resorts and are popular destinations for nature expeditions and conservation efforts due to the archipelago's incredible biodiversity, as well as tourism, sailing, snorkelling, and other water sports, with the Thirteen Islands' Council consisting of residents of other estates who maintain cultural or economic interests in the 13 islands.
