"As soon as you look at a Wyvern you know that here is a beast built for one purpose only — battle. From the solidly boned, horned head to the great barbed blade of a tail, there is no part of the creature that is not either armour or weapon. It will gore and rip with the horns; bite, chew, and swallow with the fanged maw; slash and rend with its claws; impale with the spiked wing pinions; buffet with the wings; crush with its torso; slap, slice, and stab with the tail. Its head and back are covered with wide thick scales that cannot be hacked through with anything less than a hard and lucky blow from a poleaxe. Its belly scales are softer, but to get to them you must get past all its weapons..."

"I tell you, the comparison with Dragons is a highly misleading one. Wyverns are clearly a different order of beast entirely, being as it were four-limbed rather than six-limbed. Furthermore, Wyverns have none of the redeeming qualities of Dragons. They swap pride for arrogance, and nobility for cruelty. There is probably no creature quite so vicious as a Wyvern, which of course is why they ally themselves to Orcs so frequently."
