Suluilla

Suluilla is a coastal city-state in the fictional archipelago of the Sular Islands. It sits at a natural harbor on the western shore and serves as a regional hub for trade, culture, and science. The climate is tropical with a yearly monsoon.

The name derives from local languages: "sulu" for sea and the suffix "-illa" meaning land, reflecting its maritime heritage.

Historically, Suluilla developed as a trading post in the late medieval era, grew under maritime governance, and joined a regional federation. It gained autonomous status in the late 19th century and formal sovereignty in 1952 after a peaceful referendum.

Governance is a parliamentary city-state within the federation. It has an elected City Council and an administrator who oversees daily affairs. The judiciary is independent, with a constitutional court.

The economy centers on the port, fishing, shipping services, light manufacturing, and tourism. The government supports research in maritime technology and renewable energy, including offshore wind and tidal projects.

The population is about 1.2 million, with ethnic Sula, Malay, and immigrant communities. Official languages are Suluan, Malay, and English. Religions include Islam, Christianity, and indigenous beliefs.

Culturally, Suluilla emphasizes seafaring traditions, seafood cuisine, and a year-round arts scene. Notable landmarks include the Golden Harbor Port, Suluilla National University, and the Maritime History Museum. The annual Lantern and Sea Festival attracts regional visitors.
