Wyverns are a species of creature found on Medius. They are magical feathered and scaled serpents with wings that fly through the air. The most commonly discussed variety are Wright Wyverns. Wyverns are known to come in many colors.
Wyverns are descended from Wind Dragons and have limited magic powers. Wind Dragons themselves apparently went extinct and were replaced by wyverns. Golden Wyverns, like Crunky, are the rarest and most magically powerful type of wyvern.
- Wyverns are based somewhat on the wyvern of European myth, a draconic creature.
