Dragons, wyvern and wyrm are often confused by adventurers young and old. In between the gigantic wyrm and the smaller dragon are the Wyvern, who are also the most prevalent of the three in Vana'diel. Wyverns tend to be gold in color, and have very good sight; wyverns can see in front of them and from the side for a very long distance. The notable difference between a wyvern and a wyrm is the fact wyverns rarely fly. With a wide wingspan and two primary legs, wyvern are almost birdlike in appearance (compare to the rocs).
Defeated wyverns can leave behind skin, skulls and wings – each of which has their uses by expert crafters. Some of the more notorious wyvern have developed a taste for hoarding treasure akin to their larger wyrm cousins. Defeating these creatures can be almost as rewarding as defeating a wyrm itself.
It should be noted that these wild wyvern are distinctly different from the domesticated pet wyvern, which are smaller and significantly more docile than their wild counterparts.
A wyvern (or wivern) is a winged reptilian legendary creature often found in medieval heraldry. Its usual blazon is statant (standing). The wyvern is similar to a European dragon (wyrm), but it differs in that it has only two legs (thus making it rather bird-like), cannot breathe fire, and has a barbed or snake-like tail. Occasionally, it is said to be smaller than a dragon or to be able to breathe fire. The wyvern is similar to another mythical creature, the cockatrice, which is similar to the basilisk. Its sounds are similar to the tone of a whistle or flute.
