Is it possible for Chelsie Fox to remain in command of Unity One Starbase well into 2415? (albeit with a flag rank by then) The fourth episode of Star Trek: False Vacuum will have something to do with capturing escapees from Klingon-based pirates, as well as their cargo, containing karpa swords. All that equipment will be brought back to Unity One Starbase.
This is an exceptionally late reply, as I've only just returned to the world of this wiki, but in terms of Unity continuity, it's unlikely that she'd be around in 2415. Unity Starbase itself would still be there though!
