While Colonel Kira lectures the Cardassians on their tactics, Odo returns from a successful mission agains the Dominion. Taking a break, he rests his now weakened body. Unknown to him, he was infected long ago by Section 31 and now it's only a matter of time before he succumbs to the illness. On Deep Space Nine, Worf tries to persuade Chancellor Gowron to stop his offensives that are taking the lives of countless Klingon warriors.
When the Cardassian occupation of Bajor ended in 2369, the mining space station Terok Nor was left abandoned, its systems ripped out. By invitation of the Bajoran provisional government, Starfleet stepped in to oversee the rebuilding and day-to-day operations of the newly christened Deep Space Nine.
The years of Starfleet's nonintervention into Cardassian matters, however, had taken its toll on relations with the Bajorans. Consequently, Starfleet's position was a tenuous one; many Bajorans, suspicious and hostile as a result of decades of Cardassian oppression and brutality, did not greet the Federation's presence with open arms. The Federation's assistance is put to the test as DS9 becomes a center of travel and commerce that stretches into the Gamma Quadrant.
