I have met a gnome named Tish Tickers in the top of guard tower number three who seems to be in a bit of financial trouble with a group called the Clockwork Collection Agency. In order to pay off her loan she needs five ancient silver coins. I've volunteered to help her by using the scrying stones she gave me while standing in the 'strange rainbow lights' that sometimes appear out in the wilds to attempt to find the coins among the treasures that can be acquired. She said that if I run out of stones, some merchants have been known to sell them as well.
