Horvus was a group of three Assassin-class corvettes used by the Galactic Empire during the Galactic Civil War. Carrying equipment, the corvettes arrived in the Pakuuni system along with Victory-class Star Destroyer Stalwart just as Imperial starfighters were finishing off the last of a Rebel counterattack on the construction site of the proposed XQ1 Platform NL-1 during the Battle on the Frontier.
