Seadun

Seadun is a fictional coastal region used in a contemporary fantasy setting. The term refers both to a natural dune field along the sea and to the polity that occupies the adjacent coastline. In the setting, Seadun serves as a borderland between shore and inland forest, with a strong maritime culture.

Geography and climate: The seadun coast features broad dune fields stabilized by grasses, tidal flats, and several estuary mouths. The area experiences a temperate maritime climate with regular fog, storms in winter, and mild summers. Inland, river valleys provide occasional forests and pastures that complement the coastal economy.

History and political structure: Seadun is depicted as a loose confederation of coastal towns that share a Council of Tides. Historically reliant on fishing, salt production, and trade, the region has developed crafts and shipbuilding. The council negotiates with neighboring realms on matters of fishing rights, navigation, and dune restoration.

Culture and society: The Seadun people—often referred to as Seadunners in folklore—value seamanship, hospitality, and environmental stewardship. Architecture favors low-profile houses with white facades and thatched or turf roofs suited to windy shorelines. Local traditions include the Sea Dunes Festival and rites of harvest at estuary fairs. Environmental concerns emphasize dune preservation and coastal resilience against erosion.
