Sanctuary

When a ramshackle alien vessel arrives from the Gamma Quadrant, the ship's four passengers are transported to Deep Space Nine. Kira discovers that the groups, who call themselves Skrreeans, need immediate help. With Kira's encouragement, the group's leader communicates that there are three million of her people on the other side of the wormhole who must be brought through, and they claim that Bajor is the legendary planet meant to be their home.
