Gridanias

Gridanias is a coastal city-state on the western shore of the Trivian Sea, serving as the principal urban center of the Gridanian Archipelago. It functions as a constitutional city-state with an elected council and a magistrate who serves as head of government.

The city lies in a broad delta with an intricate canal network and a natural harbor. The climate is temperate with maritime influence, yielding mild winters and warm summers. The historic core follows a grid plan, while surrounding hills and parks provide green space.

Gridanias traces its origins to the 12th century as a coastal trading settlement. It grew through guild-led commerce in shipping, textiles, and metalwork, and prospered as a regional hub. A mid-19th century reform established the council–magistrate system and broadened civic participation.

Population is around 320,000. The city is ethnically and linguistically diverse, with Gridanian as the dominant language and communities from neighboring regions. It hosts universities, museums, and cultural organizations.

The economy is diversified: port and logistics, light manufacturing, and services such as finance and tourism. The harbor handles regional trade, while markets and crafts workshops support local industry. Public investment focuses on transit, flood control, and waterfront redevelopment.

Notable features include the Old Port Quarter, Market of Lanterns, and the Gridanian Academy. The annual Maritime Festival highlights seafaring heritage with parades, regattas, and street performances.

Transportation includes a harbor, an urban tram network, and rail connections to inland towns. Canals enable inland boat traffic and flood management.
