Editing Stone Tooth

'''Stone Tooth''' was the second great [[digging machine]]s, built by the [[D'ni (race)|D'ni]] in [[5359 DE]]. It was more powerful and technologically advanced than its predecessor, [[Stone Eater]]. It is described as being almost mantis-like in its appearance, with jaws that bit away at the rock face, pouring debris through vents in its segmented underbelly into hopper cars ready to transport the material away from the work site. By the time it was used to help construct the [[Great Shaft]], the machine was over 4,000 years old, earning it the moniker "Old Stone Tooth".
