Covered with rotting meat from nearby wildlife, the Troll's lair reeks of death.  If the stench alone wasn't enough to scare off an unfortunate travelers who stumbled upon it, the bones of unlucky spelunkers would be.  The Troll places his spoils near the numerous stalagmites on the damp cave wall, his red eyes patiently scanning the dark cave interior for anything that may disturb his isolation.
The Troll's Lair, Cave

We are Knights of the realm. We serve the king and protect the outer villages. We train everyday for many hours. We have fought many wars to defend the castle and way of life.
Spelunker! What in the king's glory are you doing in this cave. This is no place for an hobbyist explorer! Hobbyist? Why, I was hired by the king to find royal treasures! I ended up a little lost though. *covers nose from horrid smell* Ah, well, um, er - i do apologize. I wasn't aware the king had sent out adventurers at the same time I've been sent to dispatch this foul beast. You mean this lovely troll? *gags* What did he do to deserve such a treatment? Well for one thing, that troll has reduced our beloved Farmer Gentry to this bit of rotting flesh. We can no longer sit idly by as our village is ravaged! Have you seen the beast? Oh dear! I didn't know such a thing. I have not seen him, but I can certainly smell him. I wonder if he has any hidden treasures down here?
