I really wish we could have seen more of them. Each has an interesting story. I mean you’ve got:
Tryla Scott, who made captain faster than anyone in Starfleet history.
Captain Rixx, who’s just plain weird (he’s supposed to be a Bolian but the makeup was never like this again)
And Walker Keel, who’s got a past with Picard, Picard owes him something, something big. And then he dies.
