You say, 'Hail, Bidils the Quickhand, here'
Bidils the Quickhand, here says, 'Hello! Isn't this exciting? I've been plotting this heist for most of my life. All I need from you is to be a [witness] to my greatness. And when we're done, we can all revel in my success and fame! Or, if perhaps you might feel shame in the presence of such a great person as myself, I will allow you to [leave].'
Saying 'leave' makes you leave the instance.
