Star Trek: Deep Space Nine

As opposed to the other main series in the Star Trek universe, Star Trek: Deep Space Nine takes place principally at a fixed location rather than on a starship. It is a large space station in a strategic location near the planet Bajor, which, in turn, is near a interdimensional wormhole that allows transit between the Delta and Gamma Quadrants of the galaxy. The planet recently was freed from occupation by the totalitarian Cardassian Empire, which still plays power politics.

Science fiction and religion is a dominant theme in the series. The Cardassians are reasonably well matched to the United Federation of Planets, which operates the station. Potentially much more powerful beings inhabit the wormhole, differentiating it from other, uninhabited wormholes. The denizens of the wormhole "have had a relationship with the Bajorans for centuries, and as they are capable of seeing time in a non-linear manner and exhibit a certain level of power they are, to the Bajorans, gods called The Prophets. To Federation officers like Commander Ben Sisko and Jadzia Dax, they are “wormhole aliens”, extraordinary and powerful, yes, but merely another in a list of powerful species throughout the Universe... There is debate about whether or not they should be referred to as deities. There is debate as to whether or not Sisko should play a role in the religious lives of the Bajorans."
