Galactonian

Overview
Very little is known about who the Galactonians were or where they came from. The Galactonians arrived soon after the Progenitors entered the Homeworld galaxy, over 10,000 years before the Dust War. Their old empire and influence spanned nearly the entire galaxy, and several Galactonian relics, such as the Ghostship, the wreckage of Karos, and others, have been found in its farthest corners.

Technology
The Galactonians possessed highly advanced technology that far surpassed that of all other spacefaring civilizations even millenia after their disappearance from the galaxy. Many of their ships were exceedingly durable and could sustain withering firepower from Vaygr and Hiigaran weaponry before succumbing to battle damage. In addition, the reliability of their technology was such that almost all of their creations remained fully functional despite the thousands of years of the Galactonians' absence.

Most armed Galactonian ships, such as the Elite Fighters, were completely automated, likely to spare the Galactonians themselves from having to engage in combat. Galactonian ships seem to have highly efficient heat diffusion systems, allowing for powerful weaponry to be installed such as those found on the Galactonian Dreadnaught, Storm Carrier, and Battleship.

Disappearance
What caused the Galactonians to leave the known galaxy is considered that they fought and lost a war against the Progenitors.
