The Hirogen civilization was highly advanced in its past, but is now in swift decline. They are a nomadic race, driv-en by the desire to hunt and prey on lesser races, or those considered worthy of the challenge. They are divided into small hunting 'packs', each led and coordinated by an Alpha. Significant study and analysis of a hunt subject is considered essential in order to understand the prey, and prevent the 'hunter from becoming the hunted'. Hiro-gen ships are well armed, built solely with combat in mind. Their technology is on par with our own; however, they rarely pursue new scientific innovation, for being so preoccupied with the hunt. They are a highly aggressive and violent people, and often they retain the body parts of their victims as trophies.
