A Saurus Knight riding a Cold One.

Cold Ones are vicious reptilian beasts ridden by the Saurus Knights of the seraphon. Foul-tempered and vicious, they embody the brute strength of the seraphon as well as their predatory nature. However, without the wit of the skinks or the discipline of the saurus, cold ones summoned by a slann would swiftly revert to their baser instincts. Thus it falls to the saurus to control the beasts and ride them to war, guiding them in the press of combat.

As creatures of Azyr, cold ones have an instinctual hatred for Chaos, and they eagerly rip apart daemonic flesh with their wickedly curved dewclaws and huge fangs. Even though the cold ones have no need for sustenance, they will still tear apart the bodies of their foes, chewing off chunks of meat whilst splattering those nearby with steaming gore and ichor.
