Trolls that spend most of their lives in the caves throughout Brightstone and Greypeak. "Cave Troll" is a common term, though Hyol Droll refers specifically to the subspecies local to northern Tharador. Hyol Droll's are more aggressive and far less reasonable than their cousins found in Tharador's central lands, and because of this Hex Hunters approach these creatures with an "Attack on Sight" mentality.
