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

I was captured in the most recent battle.  I am lucky to still be alive.  I have to escape soon.
Finally they sent someone for me! How long have you been in this cave? For a week at least I would say. Has the troll been feeding you during that week? I have only managed to sneak some scraps using my mouth while he is out of the cave. If we're going to get you out of here, we need a distraction. I don't think you can get out undetected right now. Is he still lurking about? Yes, I can see his red eyes in the dark.
