Aluvia

Aluvia is a fictional sovereign state used in speculative fiction, tabletop role-playing games, and related media. It is depicted as a land of diverse geographies and cultures, often serving as a stage for political intrigue, exploration, and frontier settlement.

Geography and environment: Its terrain ranges from fertile alluvial plains in broad river basins to upland forests and high plateaus. The Aluvian Basin is a recurring feature—a wide, fertile plain created by historical river deposition that shapes settlement and agriculture. The coast offers natural harbors and fishing communities; inland areas include towns along valleys and markets at caravan routes.

History and government: Narratives place Aluvia as an old polity with layered identities, whose political structures vary by work. Common elements include a central authority or council that governs through regional administrations. Some depictions describe a constitutional framework or a loose federation, with power devolved to cantons, duchies, or city-states. The royal or ceremonial aspects appear in some versions, while others portray a republic or technocratic governance.

Economy and society: Economies center on agriculture from river bottoms, mining resources from upland belts, and crafts such as metallurgy, textiles, and pottery. Trade networks run along rivers and overland routes. Aluvian society is typically depicted as multilingual and cosmopolitan, with communities that blend riverine, highland, and coastal traditions. Education and guilds frequently play important roles.

Culture and media presence: In fiction and games, Aluvia provides a canvas for exploration, diplomacy, and conflict, with recurring themes of identity, sovereignty, and resilience. It appears in novels, role-playing campaigns, and video games, and has inspired fan maps and wikis.
