I think there are two ships missing. One is Rhys' ship, which Val Con helps with in the epilogue. However, I think the Bedel as a whole also apparently are expecting a ship.

I got the impression that they had stopped on Surebleak for a while, but not with the intent to be permanent residents. So they probably sent their ship off, expecting it to come back after a while. However...

Maybe a future tale of the Bedel (and Korval?) will help explain where their ship has been? At least, I can hope... got all those fives to fill up, right?
