Kalthi
From Starsonata Wiki
The Kalthi are an ancient race, experienced in the art of warfare. Their single home galaxy is Hyperion, where they perfect their knowledge of battle tactics and weapons, especially in the use of missiles. Although the Kalthi have no notable ruins in their name, they are, nevertheless, dangerous alien opponents.
Supposedly, at the height of their power, the Kalthi created an outpost in the outermost reaches of known space. But such rumors could only be rumors... right?
