Radath Keiy was the Farruna captain of the Shannar.

In 2371, Keiy docked the Shannar at Deep Space 9, where Odo asked Keiy if he knew anything about the Helios, a ship that was attacking starships on the Cardassian border, although Keiy claimed to have heard nothing. Odo noted that Keiy was a untrustworthy individual who had been involved in a smuggling operation several years earlier. (DS9 novel: Proud Helios)
