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
knight
spelunker
I am a spelunker.  I work with a group of fellow spelunkers.  We explore caves in hopes of finding lost treasures once hidden.  We were hired by the king to discover lost royal treasure.  To our misfortune we are now lost.
Ah, brave knight, I thought so at first. But now it appears I am lost. And with all this rotting wildlife here, I am afraid we may become troll food soon.  There, there lad - I used to be a spelunker in my youth.  See these turtles?  Grab on to one, and follow it as it runs.  They will head to the nearest exit as soon as they smell a troll . . .though, admittedly not very quickly. Grab onto a turtle? Have you lost your mind!? They are not fast enough to escape the troll! We will surely be eaten if we follow your plan. Well, do you have any better ideas? Hmmm, let me think. Ah, I think I've got it. Do you see that pile of treasure near those stalagmites on the cave wall? It is dark but . . . yes, I do believe I can just make it out.  I don't suppose the trolls declared that on their income taxes did they? Of course they didn't! Having explored many caves as the king's spelunker, I know they are wicked beasts. But do you want to stand their pondering tax law or do you want to hear my plan? Well, I am bound to serve and enforce the king's laws, but I see your point.  Please, enlighten me. Trolls love treasure more than they love food. So let me take your ring and we will distract him. Then we will run straight out the cave's entrance and escape this awful stinking hell. But that ring was given to me by the King! . . .Fine, but I will need your witness when I talk to the King's tax collectors when they come to collect the King's due. Aye, I shall be your witness. The king trusts me. Now, let's try and get the troll's attention. Ready when you are sirrah!
