Adarak Prime was the main planet in the Adarak planetary system. This planet was affiliated with the Cardassian Union. 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...")
