The large cave is covered along the walls with bright torches.  A large hole has been carved in the ceiling of the cave, right above the ladder that descends into the underground cave.  On good bright days, sunlight directly surround the hole with the gold ornate ladder descending into the underground part of the cave.  On the walls of the cave the torches illuminate many ornate drawings and paintings mainly dealing with the history of Kings of the realm.

I am a miner who works in a dangerous mine. I do not enjoy being dirty. I make sure to get paid fairly for anything I trade.
You should probably turn around. You do not want to do down there. But my good sir, it is so BEAUTIFUL down here.  Do you know who drew these paintings on the wall? It may be beautiful but it is also DANGEROUS! I think the old tales say that prisoners were forced to work down here as slaves. This is what they did. What are you mining for down here? Coal! It is how I make my living. I just wish I didn't get so dirty doing it. For 100 gold pieces will you take me deeper into the mine? Ah you know is would be alot easier to see on a bright day? I am on the King's official business.  He has tasked me with finding new technologies for our kingdom and I believe your mine may hold the key to technologies that the world has never seen. Be it so, then you have more gold pieces to spare. I labor does not come cheap. Take this compass. If you are ever lost in a cave or mine, this will show you the way out or it will MAKE a way out.  It is priceless.  Now take me please? Ah this does seem like a rather nice gesture. You don't look like your kin on dirt. You don't mind if your clothes end up looking like mine do you? I do not mind.  If what I've hear about this mine is true, they will sing songs about you and me one day.
