Perytons are a golden, winged deer with fangs, sharp hooves and poisonous antlers. While perytons can fly, many prefer to do a combination of gliding and leaping when moving quickly.
In Secrets of the Dragon Sanctuary, the team who entered Wyrmroost were escorted by a herd of perytons fleeing the dragon Nafia. One gored Warren, seriously wounding him. Mara also tamed and rode one of them.
