Occidental, meaning characteristic of European countries, is another name for Western Dragons or Dragons of the West.  Western Dragons can be independent or members of a predatory community; sometimes, they can be the servant of a sorcerer or other powerful person. 
So popular was the belief in the prowess and power of the dragon, Ancient to colonial cartography marked unexplored regions on nautical charts and maps with the words "HERE BE DRAGONS."

Western Dragons have four thick, powerful legs and claws with the talons of an eagle.  A Western Dragon has scales covering its body, similar to those of a crocodile,  with a barbed, serpentine tail.  Their wings are membranous, like those of a bat. 
The heads of Western Dragons are large and wedge-shaped like that of a crocodile or monitor lizard with a crest, horns, or antlers.  They have huge fangs and possess particularly noxious poison; in some cases, Western Dragons exhale deadly fumes or even fire.
