Fusen

Fusen ( 浮川, Fusen) is a an, consisting of over 6,740 islands, located in north-east Sinju. It is located east of the Jeongmian island of Yeoseo and west of northern Yeongju. Fusen consists of three major archipelagic chains, the largest of which is the island of Kasho (literally meaning, the home island). The nation is further divided into four major regions and twenty unitary provinces, as well as a special administrative zone for the of the capital city of Chukyo.

According to archaeological findings human habitation of the Fusenese isles dates back to as 35,000 BC, with subsequent waves of from continental Sinju. Migration to and from Yeongju also occured, and would have a profound and diverse impact on the development of a unique Fusenese culture. The first semblance of a Fusenese nation emerged from the region of Kumahara, in western Fusen, in what is known as the Kamoi Era. The geographical term 'Fusen' would be recognized by other international entities as early as 90 BCE by other continental kingdoms, and become the commonly used term for the region and subsequent kingdom of the same name. With the rise of Cheonje, Fusen would establish itself as a of the expansive continental empire and would adopt numerous cultural and political traditions of the dynastic empire. The adoption in particular of Confucian social organization and rites would have a profound impact in the evolution of Fusense government. With the fall of Cheonje in 876, Fusen distanced itself from the continent and under the Arase Dynasty would declare itself a proper continuation of Cheonje governance, adopting the title of 'Emperor' for its monarchs.

The 12th century would see the isles of Fusen threatened by external forces of migratory peoples from Yeongju during the Koushi War. The following period would see Fusen consolidate and centralize, seeing the transition from local aristocracy to centralized meritocracy in vein of the Cheonje model. Subsequent rebellions from local lords would be common throughout the 12th and 13th century until the country stabilized around the Yadama Dynasty. But the 17th century, Fusen would have a considerable influence in regional politics with Chukyo becoming a regional economic, cultural, and political center. The Bonghwang Wars would severely dampen Fusenese influence until the 18th century, wherein Fusen would expand south and establish numerous maritime trade routes. The 19th and 20th century would see the of Fusen and the mass expansion of its colonial empire during the Great Hayago.

Etymology
The kanji for Fusen, 浮川, were first applied to the nation by travelers from Cheonje during the 3rd century CE in reference to the auroras they saw there. During the 5th century CE with the rise of a centralized government based in the Kato region, the name was popularized by scribes and government officials to describe the land they lived in. The character fu (浮) means "floating" while the character sen (川) means "river" or "stream." Due to this, the country is popularly referred to by many as the "Land of the Floating River."

Josei Era
The Treaty of Chukyo and subsequent allied occupation and would have a profound impact on the development of post-war Fusen. The dissolution of the Fusenese colonial empire was also a stipulation of the Treaty of Chukyo, and subsequent treaty accords following the Okawara Trials. The of Emperor Ensho on February 8th of 1941 was considered to be highly influential ceremonial and symbolic event of the transition towards a new 'post-war society." According to traditional line of succession the Emperor's eldest daughter, Meisho, would succeed him; however, having not yet reached adulthood at this point the throne would be occupied by a,  until the coronation of Empress Meisho in 1949. Democratization of various mechanisms of government, as well as economic liberalization, also occurred in accordance with the Chukyo Treaty.

The Akishima Diploma, signed in 1942, would serve as the basis for the nation's new constitution. The diploma served as the foundational framework for the establishment of a democratic, constitutional monarchy, modeled after the systems in place in Meisaan and Jeongmi. Political and legal reform also sought to tackle issues of the caste-like stratification of Fusenese society; particularly dissolving legal barriers to the class of citizens demarked as Fujunjin (不純人, literally impure folk) under the previous Imperial governance. The 'opening' of the Fusenese economy, beginning gradually in 1946 and continuing into the 1950s, led to a period of rapid economic growth as trade with continental Sinju flourished. Reconstruction efforts from the destruction of the Eulhae War and the payment of war repatriations preoccupied the Fusenese governmental budget for the next several decades.

Geography, Wildlife, and Climate
Metropolitan Fusen consists of a of over 6,740 islands, though the Imperial Bureau of Geographic Analysis suggests this number may have decreased due to several 'micro' island chains subsiding over the course of the last few decades, which make up a total surface land area of XXX km2. The majority of the Fusenese archipelago sits atop a, formed by the border with the tectonic region of the Okaikyo Basin. Due to its presence between two convergent tectonic plates, the Fusenese archipelago is classified a a, and is susceptible to destructive.

Of the many 'micro' and uninhabited island of Fusen, there are three major chains which are considered to be the three main geographical groupings which islands and within a region are categorized into. The largest of the Fusenese isles is the central island of wip
