You are a renowned thief. You are hired by King Alexander to go into a cave that is rumored to house treasure that is guarded by a black dragon. It takes you weeks to get to this cave in the mountains. You finally arrive, and using all of your skills, you manage to steal a precious purple looking stone that seems to call to you. You also fill your sack up with gold coins. You are halfway back to the city, sleeping in a cave. You are dreaming of all the things you're going to buy with your loot. Little did you know that the stone you stole is a rare stone that only a dragons mate can find and touch.
