|Sumei star system|
The Sumei system (jap.: スーメイ星系 Su~mei) is a star system within the territory of the Federation of Hania.
The Suumei star system was the first to discover the plane-space navigation theory. Soon, the star system began to build its nation by colonizing other star systems. That was 83 years before the Abh Empire conquered the Berisaria system. The technology was sold to many other human colonies. It played a key role in the colonial expansion of the Federation of Hania and has become the center of the Federation.
