Wyvrens are large, scaled, flying creatures, somewhat resembling dragons. Wyvrens stand about fifteen feet tall, and are up to thirty feet long from nose to tail-tip. Wyvrens have hind-legs which they use for walking and perching, and a pair of widely built wings for flight. All wyvrens have long, feather-shaped scales along the top and sides of their neck running down to just above their shoulder. These scales can be flexed to show emotional state. Wyvrens occur in a wide range of colors, including black, silver, red, and purple.
Wyvrens are ridden primarily on the Northern Continent, especially in and around The Gorge.
