The Closed, inhabitants of the planet known as Carnelion IV, were a group of near-humans distinguished by their possession of three vertical slits in place of what are commonly known as ears. They engaged in a state of war against a competing faction referred to as the Open. The arrival of Jedi Knight Obi-Wan Kenobi and his Padawan apprentice, Anakin Skywalker, on Carnelion IV brought the Closed into interaction with these Jedi. Kenobi and Skywalker's presence was prompted by their mission to investigate a distress signal that had been detected.
