Wyvern

Wyverns are a type of Dragon from European folklore.

General Description
Wyverns are a type of Dragon that are very similar to Classic European Dragons, but, instead of four legs and two wings, they only have four limbs in total — two wings and two legs. They are often depicted as dumber and smaller than "normal" dragons, although, in some settings, all dragons are wyverns.

Inspired
Wyverns (or wyvern-like creatures) in various works of fictions that were inspired by the classic wyvern include:
 * Gwythaints (The Horned King)
 * Fellbeasts (J.R.R. Tolkien's Works)
