It seems like an easy enough task: cleanse the mound of the goblins. Not so fast there, buster brown. These goblins are bat-poop crazy. Maybe from eating all the bat poop. It’s time to take arms against the goblins.
These goblins are… different. They had a decent thing going here with a fortified mound. But then they discovered the slime pools… and the enchanted mushrooms… and then they started consuming bat poop.
It’s a whole thing.
The result is that there is a mound full of crazy, magically jacked-up goblins that live a paranoid and chaotic existence.
