The IRW Loviatar was a Romulan starship, a warbird active in the late 24th century. In the year 2381, the Loviatar was dispatched to the Azure Nebula to join the allied fleet amassing there to prevent further Borg incursions. While the USS Aventine and USS Enterprise-E were on the remote side of a subspace tunnel, the allied fleet under the command of Captain Chakotay and the USS Voyager detected a different tunnel opening to allow the passage of starships. The fleet moved into battle positions, and Voyager first officer Tom Paris ordered the Loviatar to assume a flanking position along with the IKS Ya'Vang. However, seven thousand Borg cubes emerged from the spacial phenomenon and obliterated the waiting fleet. (ST - Destiny novel: Mere Mortals)
