The IRW Chairo is a Romulan Warbird in service in the late 24th century commanded by Captain Terrik. In 2378, the Chairo investigated the Vesuvi Dust Cloud to try and find a Warbird under Terrik's command only to find its derelict and the USS Sovereign so the Chairo thought the Soveregin did it. Shortly, it got attacked by several Cardassian vessels only to be saved by the Soveregin and Terrik befriending the crew.
After this, it served as escort to the Romulan ambassador at the Lyra Station talks and met with both the Soveregin and the IKV Jonka but gets attacked by several Cardassians and then by the Jonka by getting blamed for the Cardassian attack. Naturaly the Soveregin broke up Terrik's and Korbus's battle before things got ugly. (TNG video game: Bridge Commander)
