"While I appreciate your feelings of safety about this place, the Chan, or Charn as they are called where I am from, were well known to place potent arcane protections on their places, and even my poor skills at matters magical are sufficient to note that many of them are still very much in effect. They also were fond of constructing elaborate tunnels in their works, so it is quite possible that should we delve deeper we will not only find those but find them less benign than the surface. Caution is very much in order. I would also advise you suggest to their friends that warning shots are a bad idea, I rather suspect if anything hostile should come here, they may not have a chance to fire a second arrow, and if they are not hostile, they may well become so. One especially dangerous creature I know of, the Sleeper we call them, can simply move it's self into a fresh corpse, man or animal, and will walk right through a crowded village without harming a soul, but will defend itself furiously after any gesture of hostility. The necromancers of Charn were notorious for using them as trackers and assassins"

Turning to Yrees, "You should warn your friends that should they see such, they would be best to leave it alone, even a fine swordsmen like our friend Draco here might find themselves hard pressed to defeat one, and unless you burn the bodies of those who fell fighting it, it will simply migrate into one of them within hours. Would you also please ask them if they know of any entrance into a lower area? If the object of my quest is near, or even if there are any tangible clues, it is likely to be in the catacombs below."
