"See this tattoo of a devil on your chest? It's an actual devil bound to your flesh observing what you do. If you don't follow my instructions, it will manifest... Not to kill you, but anyone nearby... As well as torturing you. Just a little insurance policy to make sure you don't get any ideas."
Who needs spaceships when you can survive in the vacuum of space and greater teleport at will. Like on to the bridge of the mentioned star destroyer en masse to rip the puny mortals to pieces without needing to breach the hull, first.
OR starships that ARE devils/demons.
Not really our thing. You have to wonder about the kytons, though...
