Following a 60 year occupation, the Cardassia Empire has withdrawn from Bajor, leaving behind a planet stripped of many of its natural resources and a population scarred by decades of subjugation and mistreatment. The Federation has agreed to help the planet rebuild, and to this end, it will be sharing command of the abandonded Cardassian space station Terok Nor (now renamed Deep Space Nine) with the Bajorans. Commander Benjamin Sisko will be in charge, but he still has issues from the loss of his wife at the Battle Of Wolf 359, and to make matter worse, he also has to deal with his Bajoran first officer, who is deeply mistrustful of Starfleet and even her own government and the damage done to the station as the Cardassians left.
