The Diamond Cavern

You tell the barman that you aren't in the mood for a drink. He looks at you quizzically. "Then why have you come into my bar?" He asks you. You look him straight in the eye.
"I'm looking for a quest" You say. The barman looks at you for a second.
"Wait here" He says, disappearing into the shadows of the bar. You can tell that he's going to be a while. What would you like to do in the meantime?
