We've now been gifted with the knowledge that Starfleet has a second contact team that goes in to do all the paperwork and clear up any questions/mess left from first contact. In fact, a lot of this article might read more like a personal wish list compiled by the crew of the Cerritos, and we'd better get started before Star Trek: Lower Decks beats us to it.
Eventually, even for the seemingly most insignificant of places in Star Trek, what should now be referred to as 'Chaltok's gun' must go off at some point. We can't all do a Picard - forget both planet and person from the beginning because we're improvving our way through a poker game by the end. These planets are just waiting for someone to visit them to see how they've been getting on.
Given the 'planet of the week' approach that Star Trek is, or was, noted for adopting, revisiting strange old worlds often hasn’t been the point. Over the years this has left us with endless questions about what happened to those planets and the people on them after the starships warped away. Rally the troops - for Laris!
10. Cardassia Prime
As Admiral Wong put it, "Nobody wants to go to Cardassia Prime. The Cardassians are creeping everyone out." It's true that the levity of Star Trek: Lower Decks might take the Cerritos off the cards when it comes to sombre and solemn missions, like keeping up with the Cardassians. That said, since the end of Star Trek: Deep Space Nine, no one else (on-screen at least) has had the stomach to go back there either.
In 2375, as the Dominion War was coming to a close, Cardassia Prime was reduced to rubble. Over 800 million of its citizens were killed as a genocidal afterthought of the chief changeling with whom Cardassian leaders had made a Faustian pact to conquer the Alpha Quadrant. We can be fairly sure that the Federation didn't just leave Cardassia alone to get on with things, but it would be good to see confirmation of that in canon.
"Requiem for a Hug," anyone?
In our article '10 Story-arcs Star Trek: Legacy Should Continue,' one of the most enticing themes for a 'New Cardassia' in the beta canon is that Garak is now in charge. Just to see the former (tinker-)tailor-(soldier)spy's face pop up on the viewscreen would be worth the trip.
