The Leviathan Sea Empire, or LSDE (‘Leviathan Sea Duumviral Empire’), occasionally and historically called Asteria and the Selenes, and officially the Duumviral Empire of the Leviathan Sea, is an empire predominantly situated in the Loquille region of Petra and Southern Agalon, around the Sea of Leviathans. It is a union made up of the countries of the Jyu Dynasty and the Thalassocracy of Asteria and the Selenes. The country borders other Loquille nations such as Sante Spirite to the south of the Asteria Region, the Archduchy of Bá'álaśaya to the north of the Asteria Region, New State Preslea to the north and south of the Jyu region, and Chol and Lhinvia to the west of the Jyu region. The LDSE has a population of 1. 857. 824, which is noticeably small for its size. Most of the population live in urban areas. Bay of the Wheat Horde and Ju Latsi are the capitals with Bay of the Wheat Horde also being the largest city with a metropolitan population of 143.600, followed by Androuvin. It is also a founding country of the Loquille Alliance.

History

Prehistory

The first evidence for people living in the region the country is situated in was 5000 years ago, when the Magen first settled in the modern day region of Asteria. However, evidence for the Magen people's existence goes back 7000 years, along the west coast of Heart Lake. Archeological records show traditional jewellery, similarly worn by the Magen today being buried along with people, which most likely showed status.

The First Magen Lordship

The first Magen Lordship was established when the Magen settled in the Asterian Peninsula. They founded one of the now capitals of the country - Bay of the Wheat Horde. The first Lordship collapsed only a year after the founding of Bay of the Wheat Horde, 5300 years ago. The country was split into smaller lordships, with this period mainly being met with exploration, especially of the Seleny isles. The exploration of the Seleny isles led to an increase in infrastructure, with many cities such as Tsi and Herastas being founded.

The Second Magen Lordship

The second Magen Lordship was founded 1300 years later around 4000 years ago. This was the longest surviving Magen lordship, lasting until the arrival of humans in the year 0. It came about when the Lord of Herastas - Ƿytsen Majës at the time conquered the other Magen Lordships in the Asterian Peninsula.
