A wyvern is a type of dragon that has two legs, two wings, and often a pointed tail which is said to be a venomous stinger. It is a popular creature in European literature, mythology, and folklore, and is often used in fantasy literature and video games. The wyvern is typically smaller and less powerful than "true dragons," but still poses a significant threat in folklore. Some key differences between wyverns and dragons include:

• Physical Appearance: Wyverns have two legs, while dragons have four. The front legs of the wyvern are fused to its wings, making it easier to attack since it cannot move its wings away when it wants to use its front talons to attack back. Wyverns are also smaller than ancient dragons.

• Habitat: Dragons are often found in harsh environments such as mountains or volcanoes, while wyverns are often found in less harsh environments such as rolling hills or open meadows. Wyverns are also more adaptable and can survive in a wider range of habitats than dragons, including forests, deserts, and even swamps.

• Abilities: Dragons have the ability to manipulate magic, control the elements, or shapeshift, while wyverns lack these abilities. However, wyverns possess formidable physical abilities that make them dangerous predators, including sharp claws, strong jaws, and the ability to fly and maneuver through the air with ease. Some species of wyvern also have venomous bites, which they use to subdue prey or defend their territory.

Wyverns are important in heraldry, frequently appearing as a mascot of schools and athletic teams, and are a popular commercial logo or mascot in Wales and what was once the West Country Kingdom of Wessex, but also in Herefordshire and Worcestershire.
