The Promise of Dragons
Wyverns resemble true dragons, but are much smaller, far less intelligent and lack the forelegs of their larger kin. They have sharp talons, and crocodile-like heads with red or orange eyes. Some subspecies feature in their long, flexible tails, a poisonous scorpion stinger. They also have very large wings. Unlike true dragons, wyverns do not have breath weapons.
If flying, Wyverns can also use their teeth and stingers, but prefer to swoop down, and slash at prey with their claws, or even grab them, carry them up into the air, and drop them. Wyverns are careful to be silent when flying, and to keep their shadow unseen. This gives them the benefit of stealth if the foes are unaware of the creature. Wyverns eat the remains of those they kill, and take their valuables if they are treasure-hoarding wyverns.
