The Reyab was a Kobliad transport that was in service during the 2360s. It carried a crew of only two officers.
In 2369, Ty Kajada used the ship to transport a prisoner, Rao Vantika. During the trip, Vantika started a fire on the ship that exploded its central power linkage and started leaking energy. As a result, the ship's pilot was killed, and its aft structural integrity field and life support began failing. The on-board automatic fire suppression went off-line, causing a fire to break out. A distress call was sent and answered by the runabout USS Rio Grande, carrying Major Kira Nerys and Doctor Julian Bashir. They rescued Kajada, retrieved the body of the prisoner and had the ship towed to Deep Space 9.
Later, while docked at Deep Space 9, someone broke into the ship's cargo bay to steal a computer chip with a map of the humanoid brain from Rao Vantika's personal belongings. (DS9: "The Passenger")
According to the script for the episode, the pronunciation for Reyab was "REE-yab". [1]
The exterior of the Reyab was never seen on-screen – only a smoke-filled corridor and a holding cell.
