Sagittarius Arm
From Gineipaedia, the Legend of Galactic Heroes wiki
The Sagittarius Arm is a spiral arm of the galaxy. A spiral arm is a long, diffuse band of stars emanating outward from the galactic arm along a curve. The galaxy contains many spiral arms, each containing billions of stars and thousands of nebulae.

History
Colonization
Humankind first colonized the Sagittarius Arm of the Galaxy in 527 UC (218 IC / 3327 CE) by the Exodus Fleet. These early colonists founded the Free Planets Alliance on the planet Heinessen and quickly spread out to other nearby stars, eventually settling an area of space roughly 500 light years in diameter.
Due to the limitations of warp technology, travel between one arm of the galaxy and another was very difficult, requiring the mapping of rare navigation corridors linking the two regions. By 796 UC (487 IC / 3596 CE), only two viable navigation corridors were known to exist between Sagittarius and Orion: the Fezzan Corridor and the Iserlohn Corridor, the latter of which had been used by the Exodus Fleet in 527 UC (218 IC / 3327 CE) when they first found their way into Sagittarius after fleeing the Galactic Empire.
War
In 640 UC (331 IC / 3440 CE) the Free Planets Alliance, in the Sagittarius Arm, made contact with the Galactic Empire in the Orion Arm, and the two great nations went to war. For more than a century the great rift between the Orion and Sagittarius Arms would serve as a natural barrier between the Alliance and the Empire, turning the Iserlohn Corridor into a perpetual battlefield. When Reinhard von Lohengramm established the New Galactic Empire in 799 UC (1 NIC / 490 IC / 3599 CE), he did so by ending the Alliance–Imperial War and uniting the disparate worlds of humanity from both arms of the galaxy. The world of Fezzan became the new capital of Reinhard's empire, located between both the Orion and Sagittarius Arms, in a prime central location from which one could most easily administer a government spanning two galactic arms.
Apocrypha
Background information
- The Sagittarius Arm is named after the constellation Sagittarius, which appears close to the Sagittarius arm of the galaxy when viewed from Earth. The Carina constellation is also nearby, so this spiral arm is often referred to as the Sagittarius-Carina Arm.
