Nakamura Empire

The Nakamura Empire, also known as Anna's Imperial Remnant, was a military dictatorship formed in 12 ABY from the combined forces of the Nakamura Alignment, Imperial Remnant, Pentastar Alignment, and various other imperial warlord factions. Led by self-declared Galactic Empress Annabelle Nakamura, the Nakamura Empire had spread out in the galaxy, defeated other warlords and reorganizing their forces into the Empire.

Formation and growth
After killing those at Tsoss Beacon, including Admirals Daala and Pellaeon, she took the combined forces of each of their factions and formed the Nakamura Empire and gaining control over new territory in other parts of the galaxy as well.

After returning to her homeworld and capital, Corellia, Bells had ordered additional ten Imperial IV-class Star Destroyers for construction as she had saw the Imperial II-class as out-dated. During this time, the Empire had no desires to start wars against the New Republic and left them be with their own missions, and expansion but not into their controlled territory.

Eight Year Build-up
For eight years, the Nakamura Empire spent building up its military power and invested heavily into its navy, constructing Imperial IV-class Star Destroyers and TIE series starfighters as well as ground vehicles and its troops recruitment and maintained a strong grip over its territories.

However due to the mass production of Imperial IV-class Star Destroyers, the New Republic questioned their intentions as to why they were building up so many and only got a response suggesting that they were only making sure that their borders and territories were protected. The Navy then started to explore the Outer Rim Territories for more resources and while searching, patrol corvettes came across old debris of Clone Wars-era warships that were drifting away in space and upon inspecting the debris, they had found evidence of an outer solar system.

Discovery
After the discovery of Clone Wars-era starships debris drifting away in space beyond the southern Outer Rim Territories, the Navy was ordered to send out viper probe droids to explore the coordinates found on the destroyed starships and found a planet covered in a red surface and that it was populated with human beings. Later the Empire was ordered to send a consular ship to serve as ambassadors.
