One of this Expedition Warden should occasionally say something out of the pool of quotes.

"We are to wait here. They sent others ahead to check the tunnel interior."
"How has the Wyrmcult gained so many followers? Where are they coming from?!"
"What manner of thing would ever serve those sinister Wyrmcult wretches?"
"The Wyrmcult must be using another path. We are still finding them in Ruuan Weald."
