Dragons are large often reptilian like creatures with wings and capable of breathing fire. Different cultures have treated them as either symbols of luck and good fortune, or evil and feared beings. There are many different ways a dragon is portrayed, and they come in a great variety of colors, shapes, sizes, elements, etc.
Western Dragons - Though still vary in shape and size, the most popular version is a combination of a body shaped like a cat, with bat like wings, and covered in scales, among other reptilian features. They are large primarily carnivorous creatures that live primarily in mountain caves often difficult to reach by their sentient residence, humans. Commonly capable of flight, they can attack human settlements for their food, with little retribution. Even an impact from a ballista will cause minimal damage. A common tactic is for them to swoop down and steal live stock, or attack with their fire breathing power.
Eastern Dragons - These dragons are most often depicted as very snake like, wingless, having smaller legs, and having strong innate magical abilities. Though it is considered just about all dragons are capable of magic in some form, Eastern, especially Asian Dragons, are most magically potent. They most commonly live in rivers, and lakes and can control the depth of the water flowing through. They are most often peaceful, and kind to their neighbors. They have been known to grant wishes to some lucky humans. Their diet commonly consists of the fish in the water they live in. This motif was also occasionally used in Central America, specifically for the Sun God, Quetzalcoatl.
Pre Society - This is before major advancements occurred, the time when dragons were as they were normally perceived. Lived in caves, hoards of gold. And, in eastern country, lived in rivers. Many lived in isolation, and no single group was large enough to need a governing body.
Ancient Society - As humans came into existence, dragons soon began forming the first organized placements, made in isolated regions away from human contact. Eventually settlements began to look not unlike medieval Europe. They had teachers, elders, and scholars that would cause rapid growth in all dragon settlements. Parchment written with a fine brush under candle light were common place. A lot of the rituals and practices in magic were strongly prominent in all societies. There were occasional interactions with humans, giving to them simple technologies.
Early Society - Cultures seemed to split at this point. As humans advanced through cultures from the cradle of civilization and out through Africa and Eurasia, the dragons were not particularly stagnant either. Their people spread out over the land and migrated out, both oversea and across the land. And because of this, different cultures arose from different locales. The western dragons tended to be more egotistical, vain, and greedy, ruling for themselves to the cost and detriment of those around them. Those of the east became more benevolent and concerned about their compatriots and subjects alike. This caused different hobbies and interests, language differences, and other minor variations. By the time humans were entering the enlightenment, dragons were already preparing for interstellar travel, but becoming more and more reclusive from non-draconic culture.
Current Society - A melting pot of different world cultures resides right next to each other. They are set up with a Constitutional Monarchy with Aturis and Venuit serving as the king and queen. Though many things have been updated, magical practices are still common place, and even more so, the practice of applying magic and science together has been the cause of most of their advancements. Elders still sharing practices from hundreds of years ago, to the younger generation of dragons growing in to a technologically advanced society. While aesthetically updated, old practices remain prominent and even still influence modern technology with ancient aesthetic design.
