Thundertusk

Thundertusks are, slow witted, solitary animals. They wonder the World's Edge Mountains blasting apart mountainside with sonic blasts and crunching rock in their strong jaws. Over time these behemoths begin to turn to rock themselves, the oldest and most gargantuan of them barely able to move.
