Hippogriff

The hippogriff is a powerful animal with the wings, head, and front talons of a bird of prey and the hindquarters of a wild horse. Hippogriffs are fiercely territorial, nesting along cliffs and near to the summits of the mountains. There is a known population in the Blue Mountains and the Tower Mountains of Vestria, and in the southern stretch of the Broken Mountains. Apart from the Fell Kingdoms, the high elves are known to corral hippogriffs from the Grycawr Mountains, where they clash with the larger and fiercer griffons. 
The hippogriffs have been tamed by both men and elves, though with difficulty. The wizards of the Adamant Tower stole hippogriff eggs from their eyries in the Blue Mountains, and it is said that the hippogriffs used by the Palatine Order are descended from the very same clutches. The Palatine Order uses hippogriffs as fierce steeds, stronger than the finest destrier and able to take flight while bearing a fully armored knight. Paragon is the only city in the Realm to hold captive Hippogriffs for ready use as mounts, though in the outer realms the wizards of the Adamant Tower continue to use the majestic beasts.
