Katvus

Katvus is a fictional city-state commonly used in speculative fiction and tabletop role-playing games. It is depicted as a major coastal metropolis on the delta of the Neris River along the Valoran Sea, serving as a political and commercial hub in its imagined world.

Geography and urban form: The city centers on a natural harbor with a ring of hills. The old town lies along the northern bank; the southern shore hosts newer districts. Notable features include the Citadel of the Dawn and the Grand Docks.

History: Katvus grew from a medieval trading post into a regional power. It secured self-government through a 12-guild charter that balanced commerce and defense, and it maintained relative neutrality between rival states in later centuries.

Government: It is governed as a constitutional city-state by the Council of Six Guilds, representing major trades. A magistrate, elected by the council, handles administration; laws blend maritime custom with codified statutes.

Economy: The harbor is the backbone, with shipyards, customs revenue, and port services. Additional sectors include glassmaking, dyeing, and spice trade, with networks spanning regional ports.

Culture and landmarks: Katvus hosts diverse communities and festivals. Notable sites include the Clockspire, the Archive of Neris, and the Temple of the Serene Tide. The Old Town preserves timber-framed architecture and markets.

Transportation: A ferry network, regional rail, and a harbor tram connect districts and neighboring settlements.
