Tales of Tolgard
Chaggrins are strange creatures that look like a mole the size of a hog. They have long, filthy claws and beady, hate filled eyes. They look to be made from clumps of soil and rock in haphazard profusion.
Chaggrins, or earth grues, are magical corruptions of earth and rock. They are vicious and violent creatures that dig and borrow for no other reason than to damage the element that spawned them. They like nothing more than to slake their thirst with the blood of Material Plane creatures.
Earth grues are about five feet long and weigh about 500 pounds. These elementals can borrow through soil, earth, sand, rubble, or other lose material but not through solid stone. Its voice sounds like rocks grinding together; although they speak Terran, they are not very talkative.
