Humans, Gorgons and Hecatites are the main spacefaring races with access to Questing Country. Gorgons are reptilian and really don't like social gatherings - too much sensory input for them to be comfortable. Hecatites are basically walking rocks.

There are a few other races that don't do space travel unless they were kidnapped, since that's the only way anyone's ever gotten to their home planets. That's elves, Spartoi, and... I can't remember the name of the amphibious ones. I think it starts with a V.

I wouldn't expect many Synthetics or Diabolin in Questing Country, but stranger things have happened, I guess. Synthetics are robots, and Diabolin did a lot of the kidnapping of other races. They don't sleep, as a general rule.
