what is the difference between a wyvern and dragon
Wyvern The wyvern has often been confused with the dragon, due to the similarities between them and due to the wyvern being a lesser-known mythical creature. In the Middle Ages, no clear distinction was made between the two. Since the sixteenth century, in English, Scottish, and Irish heraldry, the key distinction has been that a wyvern has two legs, whereas a dragon has four; however, this distinction is not generally observed in the heraldry of other European countries, where two-legged dragons are entirely acceptable.[4]
