Chronicles of the Cosmos

I had this one a looong time ago.

I'm at this Black Market place standing in line. As I look around I notice that it looks like a docking bay for ships but it's also a Black Market for selling and buying illegal things. The place was inside of a mountain or something because it had a definite roof that was made of stone or rocks and a big opening for sea water and ships to come in. I've no idea how I knew it was a Black Market, I just did.
