At the edge of the wormhole, the space station Deep Space Nine™and the planet Bajor sit on what will be the front line in any Dominion attack.

If Commander Sisko fails, not only the Federation, but the Klingons, Romluans, Cardassians, and all the worlds of the Alpha Quadrant will face an interstellar war they cannot win.
