Stardate 46421.5: A Bajoran who had crossed paths with Odo during the Cardassian Occupation has arrived on Deep Space Nine. Odo gives the man a day to vacate the station, but a while later the man is found dead. The only known enemy that the man has on the station is the Constable. Meanwhile, Keiko O'Brien plans a school for the children aboard DS9, but has trouble finding parents willing to allow their children to attend her classes.
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.
