You Give the Ring Back!
"Oh, thank you, thank you!" Violet exclaims joyfully. "You have no idea what a wonderful thing you have done for me! I can never repay you enough! Let me give you this in return for your kindness!" She hand you a small dagger. The handle is a carved dragon with ruby inlayed eyes and a jeweled scabbard. You begin to protest at such a fine gift, but when you look up the unicorn has vanished from sight.
