Underground Cavern, Cave

servant
I wait on the royals.  I am very poor.  I clean the galley.
The gems in this cavern are sparkling beautifully tonight. A knight was looking at this one yesterday. Do you want it? Oh my. I am just a lowly servant. I don't deserve something as fine as this.  Yes you do.I fly around at night and see how hard you work. No, I simply cannot accept this! Can't you imagine what the royals would do to me if they find I've acquired a jewel? I am sorry. I forgot about how humans are about this stuff. You are a wonderful person. Thank you. I hate to complain, but the royals are very miserly people. I only receive pennies for my work each day. Here. Take this gold. You can stash it away! Wow! Well, I suppose it's easier to hide gold rather than jewels. I can store it in my shoes for now... Yes! You do deserve this. Please come back if you need more. I know all the hidden areas here. You are a very generous bat. How can I repay you? I am a servant, after all. Will you come and talk to me more?
