Helghan Empire (2347–2360) National anthem: "Helghan Forever"

This soundtrack originated from Killzone 2 titled by the same name.

The Helghan Empire was the totalitarian governing body on planet Helghan, ruling over the Helghast people. The founder and first ruler of the Empire was Autarch Scolar Visari.

The Empire was the instigator of the Second Extrasolar War in which they attempted to conquer the entire Alpha Centauri system and expanding its domination over Earth's colonies. They failed to achieve their goals and which lead to ISA retaliation, which in turn resulted in the death of Autarch Visari and a volatile power struggle amongst the Helghast leadership pursued. Ultimately, the Empire was utterly decimated in a planet-wide devastation, the Terracide, in 2360.

The survivors of planet Helghan were granted refuge on Vekta where they founded New Helghan, the official successor state of the Empire. Those that remained on Helghan were secretly united under Jorhan Stahl and slowly rebuilt Helghan's military might, and swearing revenge on their enemies.
