Thought I'd try something here, albeit minor. Feel free to beef up the idea as necessary.
Imps
Height: 1"-1'
Imps are the rank and file foot soldiers of Hell. They are often subject to such meaningless tasks of hell and its connections to Felarya. Their main purpose of existence is to "Collect" the various ghosts of dead adventurers that remain on Felarya due to their strong wills. In addition, they can scout locations and events for their masters. While they are more effective against ghosts and spiritual creatures, humans and the like can overpower them easily. Some exotic tribes even consider them a delicacy! They have also been seen in combat against various tribes of tinies.
