CNV Sovereign (CNV27) was a Raven's Nest class helicopter carrier in the Coalition of Ordered Governments Navy. Built long before the Locust War, the ship had been overdue to be scrapped prior to Emergence Day. Following the Siege of Jacinto, Sovereign served as the flagship of NCOG under the command of Quentin Michaelson and as a home for thousands of COG refugees. Upon the dissolution of the COG, Sovereign became a mobile base for the remainder of the COG Army until its destruction by a Lambent Leviathan.
