The Concordian mines represented a collection of mining operations that were established on Concordia, which is the lunar satellite of the planetary body Mandalore. It was generally thought that these mines were no longer in use, a belief that persisted until Obi-Wan's unearthing of the Death Watch's activities at that location in 21 BBY. During his probe into the mines, Obi-Wan was apprehended by Mandalorian soldiers. Nevertheless, Satine aided in his liberation. Subsequently, Obi-Wan ascertained that Pre Vizsla held the position of commander within Death Watch, engaging him in combat prior to his departure alongside Satine.
