Wyverns are often considered "lesser dragons", and while they are relatives, Wyverns have developed several destinctions and peculiarities over the ages since their common ancestor, the Drake (now extinct). Unlike the Dragon, it has only two legs, is more agile and unintelligent. It is an animal and as such, often referred to as the King og the Animal Kingdom in Amar. Wyverns are often depicted as Anashina's pets. They have no breath weapons.
Wyverns live in strong families - couples with their offsprings (until they are 3-5 years old). They get D6/2 eggs every year with 50% chance for each egg to hatch a live wyvern.
Wyverns are carnivoreous, eating mostly larger animals like pigs, sheep and wild boar.
Strong willed, alert, suspicious but knowing fully that they are on top of the food chain.
