The IRW Terix was a Romulan D'deridex-class warbird that was in service with the Romulan military in the late 24th century. Commanded by Commander Sirol, the Terix discovered a hull fragment from the Starfleet testbed vessel USS Pegasus in the Devolin system in 2370. The warbird was subsequently ordered to find the rest of the ship. When the USS Enterprise-D arrived with the same mission, Sirol claimed that the Terix was investigating gaseous anomalies.
After the Enterprise-D entered asteroid gamma 601 to salvage the Pegasus, the Terix "accidentally" sealed the starship inside during some "geological experiments." The Terix offered to transport the crew of the Enterprise-D out, but the starship escaped on its own using the Pegasus's phasing cloaking device. (TNG: "The Pegasus")
