(Cavus Monstrousous) is a rare breed of humanoid monster. It primarily lives in caves where it can use its gigantic ears to detect prey via sonar. Occasionaly one of these pale-skinned, small eyed monsters will blend in with human society. There they steal small children, to drag into their caves to eat or use as child-slaves. They all have colorless, short hair, only located on their head. On the surface most will assume human names such as Sarver, Jim, or Clarence. They are an all male race with no propogative abilities.
The cave monster named Sarver stole into the orphanage to capture young prey.
