T'Vran

From Memory Alpha, the free Star Trek reference.

The T'Vran was a 24th century Vulcan science vessel on an exploration mission of the Gamma Quadrant.

In 2369, on its return trip to the Alpha Quadrant, the T'Vran offered assistance to the Starfleet runabout USS Ganges, located on the outskirts of the Chamra Vortex. Although its pilot, Odo, required no assistance, he did request to have two Rakhari survivors aboard transported back to Vulcan. (DS9: "Vortex")

The captain of the T'Vran was never named, and is included on the list of unnamed Vulcans.
