Chemno

Chemno is a fictional city-state described in modern world-building narratives. Set on the northeastern coast of the Aurelan Archipelago, it functions as a regional center for science, industry, and commerce.

Chemno covers about 160 square kilometers of urbanized coastline, with a central harbor, adjacent hills, and protected wetlands. The climate is temperate with mild summers and cool, wet winters.

Originally a trading outpost established in the 12th century, Chemno grew through mercantile leagues and shipbuilding. It attained city-state status after a peaceful secession in 1846 and has maintained a stable constitutional framework since.

Chemno operates as a parliamentary republic with a directly elected city assembly and a prime minister as head of government. The city council delegates most executive powers to a cabinet, while a ceremonial president serves as head of state.

Chemno’s economy is anchored by specialty chemicals, pharmaceuticals, and logistics services. The Chemno Institute Complex coordinates research in chemistry, materials science, and environmental engineering.

The population is around 520,000, with a diverse ethnic mix and two official languages: Chemnian and Eldari.

Civic life centers on riverfront markets, university districts, and a maritime festival each autumn. The port is a hub for regional cargo and passenger traffic, and the city is connected by a regional rail network and an international airport.
