Orthrus are gigantic hounds, about the size of a bull, with two canine heads in front, and a serpent-headed tail in the rear.  The serpent's bite is poisonous.  Those bitten must Save vs. Poison or die within 1d6 Turns.  Orthrus hounds are sometimes used by Giants as guardians or pets.  Wild Orthrus packs can sometimes be found wandering in wastelands.
