Beastclaw Raiders riding a Thundertusk.
The Thundertusk is a primeval beast associated with the ice and cold. Beastclaw Ogors capture Thundertusks and ride them into battle. They can pound foes with crushing blows of its hooves and tusks, or shatter them with blasts of magical frost-wreathed ice.[1][2] Stardrakes are known to hunt them for food.[3]
