Probably around the time that Bajor becomes a member of the federation
I imagine that would be soon after Deep Space Nine ended, since it was only Ben Cisko who stopped them joining in the first place.
This poll is interesting, the rumours were saying that the new series is set after Star Trek 6, but no one voted on that option yet
There's 3 "Other" votes which haven't been commented for, I'd like to know which periods they are, Khan on Earth or other pre Enterprise? Mirror or Negative Universe? Same timeframe as any of the current series? Further into the future where timeships are used? What ever it is please leave a comment.
