 Commander Benjamin Sisko, whose life has changed after his wife was killed in the battle with the Borg at Wolf 359, is to take command of the space station Deep Space Nine near Bajor. The station was built by the Cardassians, but recently taken over by the Bajorans after a very oppressive occupation of their planet was ended. Sisko has one hell of a task before him. The station is in ruins after the Cardassians stripped it, merchants are preparing to leave and its Bajoran commander major Kira Nerys seems to dislike the Federation. When Sisko gets to talk with Kai Opaka, the Bajoran religious leader, she tells him he is the long awaited emissary and shows him a  Tear of the Prophet , a mysterious looking orb that enables him to relive memories. Kai Opaka tells the other orbs were stolen by the Cardassians looking for the Celestial Temple. She urges the DS9 commander to find it before they do. After science officer Jadzia Dax, a Trill, thinks she has found the possible location, she and Sisko make a startling discovery.
