There ain't a lot of rules on the space station. Just the standard ones-- don't steal shit, don't start fights, don't finish 'em by killing anybody. I'd add in don't fuck with anybody with horns and grey skin, we can be touchy and we can tell what you're feeling to some extent. And don't touch a gorgon's tentacles, they get pissy about it.

As for my universe, that's more complicated.
