Commander Sirol was a 24th century officer in the Romulan military and captain of the Warbird IRW Terix.

In 2370, Sirol discovered a fragment of the experimental USS Pegasus in the Devolin system, and was assigned to find the rest of the ship in the system's asteroid field. When the USS Enterprise-D arrived on the same mission two days later, Sirol claimed he was conducting a survey of gaseous anomalies.

After the Enterprise entered a large asteroid where the Pegasus had settled, Sirol fired on the asteroid and sealed them inside, claiming the Romulans were conducting "geological experiments". Sirol offered to transport the Enterprise crew out and return them to the Federation after a "short stay" on Romulus, but the Enterprise escaped on its own by means of an illegal phasing cloaking device that had been tested on the Pegasus. The Enterprise decloaked in front of Sirol, and informed him that the Romulan government would be contacted shortly concerning the incident. (TNG: "The Pegasus")
