The Vengeance Fleet was a makeshift military force created by the Army of Humanity for the final assault against Omnius in the Battle of Corrin. The LS Serena Victory was the flagship manned by Champion Vorian Atreides and Bashar Abulurd Harkonnen as his executive officer. Among the fleet was also a "diplomatic" ship with Viceroy Faykan Butler and Rayna Butler along with other officials and nobles.
