Stardate 47282.5: Quark meets with a woman on Bajor who wants him to acquire a container. During the Cardassian's occupation of Deep Space Nine, the container was hidden in a wall located in one of the station's recently converted storage facilities. Quark believes that he is working for the woman's interests, but the woman has an accomplice and a history with DS9 that stretches back to Odo's first days as Constable in a case that involved Major Kira Nerys.
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.
