Speaking of caves, I was thinking about having an alien race that builds everything in hollowed out caves, maybe in cliff-sides (like the Puebloans), or in completely underground caves. They probably might even hollow out asteroids, moons, and dwarf planets to make space stations. So imagine going inside a cave and seeing apartments, hotel rooms, restaurants, stores, etc.
