Enai-ra was an ocean-going steamship of the Yemai Empire on the planet Sigma Niobe II. It was commanded by Captain Nohin Yiamed-Ba, and was the flagship of the merchant fleet commanded by Admiral Deyin Kaiyel-Ned. Captain James T. Kirk and four other members of the USS Enterprise signed aboard the Enai-ra at the port of Reihairem, as it set sail for the Ilaiyen Archipelago. (TOS - Constellations short story: "As Others See Us")
