The N-Body Problem

I had been expecting many things upon arrival to the nearby city. 

Part of me had expected our bad luck to continue, that the city wouldn't really be a city but would be more like a small town filled with mud huts of primitives who would never be able to help us. 

Part of me had expected some kind of megacity like Prespian City, filled to the brim with thousands of different species. 

What I hadn't expected was another mountain, at the centre gouged out of the rockface itself was a gigantic metal doorway. The entrance to some kind of underground metropolis. 

The predator, which we really had to find a name for at some point, sensed my confusion and sent one back, this time accompanied with some blurry images. Images of death and destruction. Images of burning fire. 

I was starting to get the idea that the orbit of the planet wasn't quite as stable as I had originally believed.
