Stonehorns are huge creatures, with massive arms and barrel chests. When they stand, they are some 16 feet high. With grey skin, long arms, and a huge belly, the stonehorn crouches on two long frog-like legs. Beady eyes peer out from beneath a broad head crowned by massive horns. The stonehorn's eyes are hollow pools of gray indifference. Their lipless mouths, lined with thousands of tiny, sharp teeth remain clamped shut unless they feed. The stonehorn prefer to dwell in swamps or marshy areas where their height and strength give them an advantage. Scholars maintain that the beast was born of the toads and frogs to which it bears a slight resemblance.
