In 2154, a group of Rigelians kidnapped Dr. Phlox from Earth aboard a Rigelian freighter. Their flight plan logged their destination as being the Proxima colony. However, its trajectory was, in fact, on a course near Klingon territory for a transfer-rendezvous. The freighter made the rendezvous with a Klingon starship, and was subsequently destroyed.
At the same time, the freighter's warp trail was being tracked by Enterprise NX-01, which was several hours behind. When Enterprise arrived at the rendezvous coordinates, it discovered the freighter had been destroyed, and a number of Rigelian bodies were found in the debris. Due to a deception made on behalf of Section 31, it was initially believed that the ship had been attacked by Orion raiders based on the weapons signatures, but its destruction was later determined to have been caused by Klingon disruptors.
