 * Very clever how you got in here like that, . What? Surprised that I know your name? I'm a demon, that's what we do. I also know your true name, so you'd better buy something expensive.
 * Here for the rod? Or maybe you're simply stocking up on runes? Wait a minute! Are you just trying to offload a whole bunch of junk on me?! Curse my never-ending compulsion to buy, buy, buy!
 * What? No, I don't do armor repairs. Everlook is about a mile to the north, brother. Now buy something, or move along before I summon my warlock to deal with you!
