Adarak Prime was an inhabited planet. It was the main planet in the Adarak planetary system. This Cardassian system was located in the Alpha Quadrant. During the Dominion War, the planet was the location of a weapons depot, which was defended by a single Cardassian garrison.
In 2375, Odo identified a weakness in the depot's perimeter defenses which could be exploited by a small team. The mission was undertaken by the Cardassian Liberation Front. (DS9: "When It Rains...")
According to line cut from the final airing of DS9: "Penumbra", Vedek Oram's monastery was located in "Adarak," a region on the planet Bajor.
