Dragons are the oldest race of creatures in the material plane. They were created by Ymir in her image. When you come across them, they are often ancient, having lived thousands of years at a minimum. The eldest are practically ageless.
Elder dragons (or Archdragons) are the oldest and most powerful dragons, commanding reverence and fear wherever they appear. They were born directly from Ymir, before time even started, with Dragon Lord, Placidusax being the first.
A very strong subset of dragons that born shortly after the Elder Dragons. They are almost as old and almost as powerful

Common Dragons
This sub-group of dragons are the most common type of main dragons. They are intelligent creatures but far less powerful than Ancient or Elder dragons. They can often be found flying over the waters around The Dragon Isles and nested in caves and mountains in nearby territories. The older and more powerful of these dragons will venture out and make nests all around the world.
Lesser Dragons
Info
Lesser dragons are creatures that have descended from dragons. There are a whole range of sub-species that range from intelligent to beats.
During 02 - The Second Age, the Dragons slowly lost control of the world as mortal creatures began to rise and spread. The stagnant world of dragons slowly transformed into the changing world of mortals with kingdoms rising and falling. Dragons still held power as these deific creatures that were often worshipped and revered.
Religion
Dragons have no common relationship to religion. They may have been born directly from Ymir, but they do not worship her as creator. For dragons, Ymir is simply both mother and father, creating them in her image. Dragons are often worshipped themselves, however. Often to try and appease these most powerful creatures and sometimes in lieu of worshipping Ymir as the dragons can grant real benefits to their worshippers where Ymir typically does not.
Trivia and Useful Info
