Halless 1 is the first planet in the Epsilon Indi system. The Race sent a Conquest Fleet under Hisstan the Conqueror to Halless 1 millennium ago. The Fleet easily conquered the planet and integrated its natives, the Hallessi, into their Empire as full citizens.
At the time of the arrival of the Race's Conquest Fleet, Halless 1 had been unified under a single ruling imperial dynasty. The Hallessi Emperor was deposed by Hisstan and the Race's Ssumaz Emperor was recognized as the Emperor of Halless 1.
