Captain Mathias:
People shouldn't spread false rumors! I've heard them all before... devil worshippers, vampires, blah blah blah... The ravings of drunks! This town is well-protected by our royal guards! Don't worry!
Who is spreading these lies? If you hear anyone saying such rubbish, tell me immediately! I know you wouldn't be so stupid as to do it! The rich people in this town take a very dim view of such groundless fear mongering! If I were you, I'd watch what I say!
