It is a dark cave that is cold and damp inside. The floor is rocks covered it bat poop. It is damp from the ceiling dripping of water. The cave just goes on what seems to be endlessly into the dark abyss. The only lite you can see is from the distance entrance of the cave.

goblin
The goblin lives deep inside of caves far away from the sunlight. The goblin lives on deep cave algae and small critters and bugs that he can catch on the cave floor. The goblin avoids people as much as he can to stay alive.
Orc...where are you? I am here by the bush, goblin. It's so hard to see in your cave...I almost bumped my head...are you ready to go? Yes, I got my bag, I'm ready. Are you? You bet I am...I've been looking forward to this for weeks.  Ugh...I just stepped in something slimy.  Bat poop, probably. You want some corn? My bag is full of it. Let's save it for the trip...we have a ways to go to get to the field.  Once we are there everyone will put their food together for the feast. Mmm, that's a good point. I'm excited for this feast. Who else do you think will be there? All the goblins and orcs from the surrounding villages...the Goblin King will be there...I am so excited. Maybe some of my friends will let me live with them in their village. My cave is nice, but it's so deep and secluded. And smelly man...how do you live with all of this bat poop???  My cave is damp and very welcoming to goblins. The bats keep me company, and the poop keeps out wild animals. Is your cave also welcoming of orcs?
