' is also sometimes called "DS9". It is set in the late 24th century, at the end of "The Next Generations time line and the start of Voyager's. It is not like "TOS" and "TNG" because it is set on a space station and is not about exploring. This means it has more soap opera elements (lots of stories about the characters). Most of the stories are about the Cardassian race and the war with the Dominion.
