"Okay. It would be best if you weren't to audition him yourself though. As I said, he's got brain-damaging stuff. It would be best just to turn him away, but if you're skeptical..."
Zanny twinges a chord on his lyre. Any nearby people listening in on their conversation (besides the Moff himself) now have an annoying buzzing in their ears that makes it very hard to hear what he's saying.
"I'd recommend having some random NPC listen to it. So you don't mess yourself up. You'll tell I'm serious once it starts foaming at the mouth or something."
The buzzing stops once he's done giving potentially-offending advice.
"Anyway, I'll stop by when it begins. Get some great bands to play so I look even better once I overshadow them!"
Zanny's last sentence is said in jest as he walks away. The bard will walk out of sight in any direction, then play a silent chord of magic. Now invisible, he'll wait around for either Pete or Darcy to show up.
