The Selcundi Drema system was a planetary system located in the Selcundi Drema sector. Prior to the mid-2360s, this system had at least five planets, and one of them, Drema IV, was inhabited by a native species. Sometime before 2365, the fifth planet, Drema V, had shattered and the debris formed into an asteroid belt. In 2365, the USS Enterprise successfully prevented Drema IV from being destroyed by geological instability. (TNG: "Pen Pals")
