Stardate 52152.6: Accompanied by Doctor Bashir, Chief O'Brien, and Quark, Worf sets off on General Martok's Bird of Prey on a glorious mission to attack a Dominion shipyard. Using the element of surprise to destroy the base, Worf hope that this mission will help Jadzia reach Sto-Vo-Kor. On Deep Space Nine, the Romulan armament on one of Bajor's moons has been found out and Major Kira blockades the moon so that no Romulans attempt to land on the surface. On Tyree, Captain Sisko, his father, son, and Ezri Dax, look for the message that the Prophets have been guiding Benjamin towards.
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.
