I was just thinking, hmm, you probably could, and I started to rationalise it into something, and I was doing quite well until I came to the ghost part and stopped. I can do the spaceport on a spaceship (it's a very big ship of some kind! some of the travellers there are on their way to do terraforming and have very strange ideas about that, but my brain baulked at the ghost.)

... also FIve and Tegan, do they have the GRavis with them or has he been dropped off already? Because then it is a giant space ship with a spaceport, cult terraformers, a ghost and a giant gravity influencing insect.
