Was that "half way across the galaxy" an exagerration or can they really travel that far in that amount of time?
Khlyen and Level 6 seem to have access to technology unknown in the Quad, like FTL (quantum/ansible?) communication. Maybe that ship is unusually fast. There is something odd about it, apparently, given the weird image distortion they use on the scenes of Khlyen and Fancy Lee inside the ship.
I was a bit disappointed, because when D'Avin first mentioned his home planet here, I thought I heard him say it was "a Ringworld." That would've been a hell of a thing to see. But it turned out to be just a ringed world. I guess it wouldn't have made a difference, though, if they only had the budget to show the inside of a small cabin.
