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.
Perhaps I can use this club to defend my captured brother... So many morsels lying around.... What a bold creature, to feast in this lair. How long will the troll be away? One can never tell, he keeps no schedule. How long have you lived here, rat? I cannot really say, I just know there is always an abundance of food here. I simply hide in the walls when he returns.  Do you know when he captured my fellow knight? It was a few days ago I think? My sense of time is a bit off from staying in this cave. Have you seen what he does with his prisoners? Judging by the bones I believe he does eat them, I have never witnessed it though. How do you know you're not feasting on human flesh now? I stick to the cheese, though I suppose I would not know the difference. Meat is meat yes?
