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

a rat feasting on leftovers
Mmmmm, leftover banquet food! I'm just a rat so this is amazing! A little meat, a little cheese...how about a little EVERYTHING!
Nibble nibble. Yum this is so tasty.  Tell me rat, do you know where to find the troll? hmmm, I think I saw him go back further into the cave.  He won't be happy to see you here. I better hide his weapon, he will be much less dangerous without this big club to crush me. You have fun with that, I'm going to eat this now. Eww. I bet the troll won't be as disgusting as that.  It's delicious, you can have some if you want.  I cannot waste more time here, I have to kill this troll before he hurts more people. Sounds a fools errand. I am a knight, this is what I have trained for. I must defend the king's castle at all cost. That sounds awful.  What about you, rat? I suppose you come from a noble family of rodents?
