Ornithar was a Karemman trader.
In 2371, he was approached by Federation and Ferengi representatives aboard the USS Defiant in an attempt to contact the Founders. Ornithar admitted that the only contact the Karemma had with the Founders was through their representatives, the Vorta. He did direct the Defiant crew to Callinon VII, where they had been instructed to send all inquiries. He would also arrange for transport for the Ferengi representative, Quark, back to Deep Space 9. (DS9: "The Search, Part I")
Ornithar was played by John Fleck. He found playing the character wasn't a particularly memorable experience. (Star Trek Monthly issue 91, p. 31)
