Once they come through to the Prime Plane, they set about clearing the area around them by forming headmarks out of the nearby earth. The headmarks attack everything in sight. Once all living things stop moving, headmarks resume a state of quiet senescence, brooding about the state of the universe. \n'b' Headstones can speak but rarely bother to do so. When they do speak, they speak in halting phrases, often calling the creatures who communicate with them \xe2\x80\x9cdumb.\xe2\x80\x9d Headstones tolerate two things: chewy materials like gum and squids. When they appear underwater, squids will often make their homes in the nostrils or mouth of the headstone. If given anything to chew, the headstone will not attack while it chews the gum. It\xe2\x80\x99s presumed that in the Elemental Plane of Earth, similar creatures live a symbiotic existence with the headstones, performing a service by cleaning out any parasites they might have (parasites that are unknown on the Prime Plane) and that the gummy texture reminds them of a material they eat on their home plane. \n'b' Animated by headstones, headmarks are smaller versions that lack the arms and torso of their progenitor. They are temporarily formed from earth and have just the brooding heads of headstones. Unlike their parent, headmarks can fly and will create a form of wall-like defense around the headstone to defend it. \n'b' Also animated by headstones, blockstones are flying, animated cubes of earth that act as a shield and defense for headstones.'
