- When is Star Trek: Discovery set? 2 answers
I have just finished watching Star Trek: Next Generation and Voyager they seemed to be in the same timeline and fit together.
I have now started on ST:Discovery.
The timeline doesn't make much sense to me because in *Voyager they had insane shield technology that Janeway's future self gave to Voyager before their return.
So my guess is that Discovery is prior in the timeline. Is my confusion because I haven't yet seen Deep Space Nine?
