Shudde M'ell is "a great gray thing a mile long chanting and exuding strange acids... charging through the depths of the earth at a fantastic speed, in a dreadful fury... melting basaltic rocks like butter under a blowtorch." Shudde M'ell is the supreme regent of the chthonians, a horrifying race of burrowing creatures, and is probably the largest and most malignant member of his kind. According to some legends, he was once imprisoned beneath G'harne, but now he is free to wander the earth with his kin.
