Sarish Rez was a Bajoran and First Minister Shakaar Edon's adjutant.
In 2372, he accompanied Shakaar to Deep Space 9 for negotiations on Bajor's entry into the United Federation of Planets. He cooperated with Odo in providing security for Shakaar, who Odo believed was targeted for assassination by the True Way, a Cardassian extremist group.
During a gathering, Sarish planned to arrange a springball game with Vedek Tonsa, planning to use the opportunity to ask Tonsa to support Shakaar in the Vedek Assembly. (DS9: "Crossfire")
