Tubea

Tubea is a fictional city-state and archipelago commonly featured in speculative fiction and tabletop role-playing games. The polity centers on a group of islands in the eastern sea known as the Tidechain, with Tubea City on the largest island serving as the political and economic capital. The name is used for both the state and its main urban area.

Geography and climate: The archipelago comprises nine main islands and numerous islets, with low-lying terrain and scattered lagoons. The climate is tropical maritime with hot, humid summers and mild winters; monsoon winds influence naval trade and fishing patterns. The population is described as diverse, with Tubese as the de facto official language and widespread use of English in administration and commerce.

History and government: In most depictions, Tubea emerged as a major trading hub in the late medieval period and gradually developed self-rule, formalizing a constitutional framework in the early modern era. The state combines a bicameral legislature with an appointed governor and a maritime code that governs shipping, fisheries, and port management. The armed forces are small and primarily oriented toward internal security and coast guard duties.

Economy and culture: The economy relies on shipbuilding, coastal fisheries, and transshipment services, supported by duty-free zones and a growing tech sector focused on maritime surveillance and renewable energy. Cultural life centers on harbor districts, with annual festivals, crafts, and a tradition of sea navigation knowledge. Notable landmarks include the Glass Market, the Tide Gate, and Harbor Square.
