Grollock
  These twisted monstrosities may have once been human, but now they are the scourge of any who dare venture into the ruins of old places. Though humanoid in shape, their arms, back and legs are covered in small, bony spines. They communicate with their own kind by rubbing these spines together, making a deep, buzzing sound similar to that of an insect. They are strong, with thick, bony hands that they will use to bludgeon their foes to death before feasting upon them; but do not underestimate their intelligence, as that has been the end of many who stumbled across them.
