Probably the ancestors of that surly Bringloidi group from "Up The Long Ladder".Haven't seen this mentioned yet here, but Craft's "enemy" the V'draysh are actually a mispronounciation of "Federation" (verified by Chabon himself on social media here: https://i.imgur.com/hMaCVqr.jpg ).
So apparently the Federation does indeed still exist during this time. I guess Craft is part of some human colony that has broken off from the Federation for whatever reason (or was never part of it to begin with).
(TNG Season 2- Episode#18)
I wouldn't put it past them to have rejected the Federation just to be out on their own and they certainly had very different ways of pronouncing things.
