This is Original Sonhel, aka The First World...
... and this region of the South Sea is where the amarian story begins.
Contrary to popular belief, the Amarian Republic is not the predecessor state of The Combine. The amarian people have their humble roots in the northern regions of the Umetuč Island, inside the borders of what will be called The United Heptamates of Greater Ngenceba, C'aarllaac & Xirakekunnae.
The United Heptamates (aka NCH) were founded in 2400, after several decades of infighting, civil war, ethnic cleansing and political persecutions carried out by leader of the Work & Prosperity Party Gamabhat Mpodo (written "Gamabrat B̨odo" after the reform).
Regardless of the bloody origin of the country and its deeply xenophobic and bigot culture, B̨odo's NCH was extremely tranquil and carried out a freidnly and neutral stance in foreign politics.
Under B̨odo the first railway network began construction between the february and march of 2400, military operations were issued to enlarge the country's borders eastwards and the first commercial pacts with Morich (resources exports) and Kanbon (weapons imports) were signed.
