"An adventurer! It's been a long time since I met anyone else down here."
"I was once an adventurer, like yourself, long ago... but Xantan discovered me and cast a magic on me that keeps me from leaving this place. I can't even move from this very spot!"
"You don't know who Xantan is? Then what are you doing in here?! Xantan is a powerful wizard... well, not that powerful, but more powerful than me! He lives at the bottom of this dungeon, and has for hundreds of years at least. That's all I know about him, and most of it I learned from the deeper denizens of this dungeon."
