Wyverns are serpentine relatives of dragons that live in the woods of Mordavia. They have bat-like wings that keep them airborne nearly constantly, as they have no hind legs. Their claws and teeth are razor sharp and venomous, as is the stinger on the end of its tail. They also have powerful breath attacks. All in all, wyverns are deadly more often than they are not.
- "Wyverns are relatives of Dragons. They are smaller and do not have hind legs. Their bodies are long and snake-like, the wings bat-like. They attack with their teeth, claws, and the poisonous sting at the end of their tail. Their poison can quickly weaken even the strongest Hero, so be sure to have a Poison Cure potion on hand." (Excerpt from QfG4)
Wyverns are a random monster in Quest for Glory IV: Shadows of Darkness.
