Stardate 47391.2: A ship from the Gamma Quadrant comes through the wormhole where the passengers are beamed aboard Deep Space Nine. The communicator at first has trouble dealing with the language of the new guests to the Alpha Quadrant, but it eventually manages to translate the language of the Skrreeans. Having been recently liberated from their overseers by a member of the Gamma Quadrant's Dominion, the Skrreeans have come through the wormhole looking for the planet Kentanna, where they will live peacefully.
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.
