The Talvath was a Romulan science vessel that was in service in the mid-24th century. In early 2350, the Talvath, operating under the direction of Dr. Telek R'Mor of the Romulan Astrophysical Academy, began an extended three-year scientific mission. In mid-2351, the Talvath encountered a micro-wormhole in Sector 1385 of the Alpha Quadrant that led to the discovery of the Federation starship USS Voyager in the Delta Quadrant, located in the year 2371. The Talvath was scheduled to complete its mission and return to Romulus in 2353. (VOY: "Eye of the Needle")
