Artaleirh was an M-class planet in the Romulan Star Empire. During the Romulan Civil War in the 2270s, Artaleirh sided with the Free Rihannsu. (TOS novel: The Empty Chair; Star Trek: Pendragon) The decommissioned D'dhael Aish'anh-class warbird IRW Gauntlet, which had been captured by the Free Rihannsu during the 2276 revolt, was a museum ship in the Artaleirh system, but by 2410 the Grand Fleet was so short of ships the vessel had been refit and re-commissioned.
