Asgardian Empire

The Asgardian Empire (Imperatum Asgardii or Imperium Asgardium), known by locals as the Golden Realm (Kitel Orim) was an ancient interstellar Human state that bordered the Atrisian empire (which the Asgardians called the Kitel Phard). After a devastating space war with the Atrisians that lasted over a millennia, the Asgard system and its domains joined the Galactic Republic. The Asgardian civilization mysteriously vanished; it's possible that Asgard's population was eradicated by a series of natural disasters, though the disappearance of Humans on other Asgardian worlds remained a mystery.
