Dr. R'Mor at the communications station aboard the Talvath
The Talvath was a Romulan science vessel in operation during 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 lead to the discovery of the Federation starship USS Voyager in the Delta Quadrant, located in the year 2371.
The Talvath would conclude its mission and return to Romulus in 2352. (VOY: "Eye of the Needle")
