Stoneborers are blind, subterranean beasts that chew through rock with crystalline teeth.
Description
Resembling massive moles with ridged, gravel-like hides, they vibrate as they dig, leaving behind tunnels that reshape the underground. Though destructive to stonework, their burrows are vital to the breathing of the mountains.
