Rock Beast

Little is known of this massive, 20-foot (~ 6.1 m) creature, other than at some point, War Prince Alloran-Semitur-Corrass or Visser Three managed to acquire the DNA of this species.

Biology
It appears to be made entirely of rock. It stands on three thick legs, with two massive arms jutting out from its body, juxtaposed with a head about as big as a Human's. Most likely due to their size and composition, these brutes are incredibly strong, able to jam their fingers into concrete and rip it up.
