The Burrowing Things

The Burrowing Things, current adversaries of the Dwarves, are a race of bizarre, animalistic underground dwellers. Burrowing Things, are regarded as being the often searched for Earth elementals, but instead of being made of mud and stone, they are made of a bizarre 'living soil', mud that pulses and shifts with the beat of the Thing's single major organ, which is a combination heart and brain.
