Demon bard makes you their worshipper

You've heard the rumors about bards, haven't you? That we'll completely and utterly mesmerize you, and you'll be made to dance to our tune forever, and yet strangely that doesn't put you off. You think you can outlast, don't you? No matter how provocatively I dress, or how sensually I move my hands up and down my pipe, or how I caress the fipple with my tongue you think you can outlast... Well, you are wrong!
