The Kaarenth Impalers began as the staunchly loyal guardians of the now-defunct Paecian Empire. Thousands of years following that empire's demise, the name was revived by Palpatine, the creator and leader of the Galactic Empire. Ennix Devian was appointed by Palpatine as his own "Karenth Impaler," and given the responsibility of pursuing and eliminating those he considered disloyal to him.
