The sentient Wyverns of Kalimdor were eager to ally themselves with the Shamanistic Horde. Impressed by the Orcs' commitment to honor and victory, the Wyverns allowed the Orcs to ride them into combat against those who would disturb the tranquility of Kalimdor and its denizens. The Wyverns, who share a common ancestry with both Dragons and Gryphons, use their powerful talons and razor-like fangs against both airborne attackers and ground troops.
