The Severus is one of the most dangerous ships in the galaxy. Designed by Kuat Systems Engineering for the Cylon Imperium it is described as a "ship killer." Using many state of the art technologies, KSE managed to create a vessel that Empress Eve found to be extremely impressive. Because KSE shipyards are not equipped to manufacture vessels of such magnitude, they only designed the Severus, Cylon Imperial Shipyards built it. It was an extremely time consuming and expensive vessel to create. Therefore the Cylon Imperium has only built a few, the Severus, however, was the first of these vessels. This vessel was later stolen by the Dark Jedi Sion. When he became the powerful Sith Lord Darth Terris, the Severus became the flagship of his order.
