The Cardassian system was an inhabited planetary system. This
system was located in the Cardassian sector. This sector was a
region of space in the Alpha Quadrant. The system consisted of a
primary and five named planets. One of the planets, Cardassia
Prime (Cardassia II), was inhabited by the Cardassians, a warp
capable species. This planet was the capital of the Cardassian
Union. (DS9: "Explorers") The planets Cardassia III, Cardassia
IV, and Cardassia V were colonized by the Cardassians. (DS9:
"The Homecoming", "Shadowplay", "Prophet Motive") In 2375, the
Dominion began their withdrawal to Cardassia Prime during the
waning days of the Dominion War. The Allied Forces, or Allied
Fleets, planned a risky and costly military operation to end the
war by penetrating the system and engaging the forces stationed
in orbit of Cardassia Prime. (DS9: "The Dogs of War") It was
never stated in the canon if Cardassia I was an inhabited
planet. "Tactical Display 7624N" was reproduced for the Star
