Ktath'atn was a dark forest planet that was ruled by the Queen of Ktath'atn, whose hive fed on the human inhabitants. It was the location of the Citadel of Ktath'atn, which stood over a village. Doctor Chelli Aphra traveled to Ktath'atn with Luke Skywalker to visit the queen, hoping that she could activate the Rur crystal.
