The Métensis system was a star system located apart from the principal space routes of the galaxy. It contained two planets and the planet-sized droid Kalonn, orbiting around a small red star.[1]
During the Galactic Civil War, several Alliance vessels were lost in the system. When a team came to investigate, they accidentally managed to awaken Kalonn, a gigantic droid. They managed to destroy it before he could leave the system.[1]
