Sinui

Sinui is a fictional toponym used in fantasy and speculative fiction to denote a coastal city-state and its surrounding region. In many world-building narratives, Sinui lies on the western coast of the continent of Eldoria, at the mouth of the Serin River, and functions as a major hub for maritime trade and cultural exchange. The name is variously attributed to an ancient Sinui language or to a river-based toponym in different narratives.

Governance is typically depicted as a merchant oligarchy or a guild-based council, sometimes called the Nine Merchants Council or simply the Council of Trade. The city-state is often portrayed as ethnically diverse, with neighborhoods organized around crafts, merchants, and maritime families. Its strategic location makes it an entrepôt between inland realms and sea routes.

Economic and cultural life centers on port commerce, shipyards, textile production, and spice or dye trades in some variants. Architecture combines stone foundations with timber framing, and public spaces emphasize the harbor, markets, and ceremonial piers. Public festivals celebrating harvests, tides, and trade appear in several versions.

Sinui has no basis in real-world geography; it is a fictional construct used in various works. Consequently, details vary by author and series.
