The third STAR TREK series concerns Benjamin Sisko, commander of the starship Deep Space Nine, who discovers the first known stable wormhole - a virtual shortcut through space that leads to the Alpha Quadrant to the Gamma Quadrant on the other side of the galaxy. The Gamma Quadrant is governed by the Dominion, a group led by the Changelings - an group of shapeshifters which counts DS9 crew member Odo (Rene Auberjonois) among its numbers. The Dominion has become a violent force in the galaxy, and the Deep Space Nine and its crew has become the only home in upholding the way of life established by the Federation.
