The Na'Tan is a Narn freighter. In 2259, the Na'Tan went to Babylon 5. The Na'Tan fired on the Centauri liner, Molios, while waiting to dock with the station and destroyed the liner. The battle was witnessed by an Interstellar Network News crew on the Earth Alliance transport, Hyerdol.
The Na'Tan fled the area and a fighter wing from the station was sent to capture the vessel.
