Zytchin III is a planet once visited by Starfleet officer Jean-Luc Picard. Captain Picard once stayed on this world for several days, and told Beverly Crusher he enjoyed his stay. When Dr. Crusher tried to recommend a rest leave for him in 2366 and reminded him of Zytchin, Picard claimed he had lied about his fondness for the place. (TNG: "Captain's Holiday")
